Apex Basics & Database

Question 1

As a language, Apex is (9 things):

Answer 1

• Hosted—Apex is saved, compiled, and executed on the server—the Lightning Platform.
  
  • Object oriented—Apex supports classes, interfaces, and inheritance.
  • Strongly typed—Apex validates references to objects at compile time.
  • Multitenant aware—Because Apex runs in a multitenant platform, it guards closely against runaway code by enforcing limits, which prevent code from monopolizing shared resources.
  • Integrated with the database—It is straightforward to access and manipulate records. Apex provides direct access to records and their fields, and provides statements and query languages to manipulate those records.
  • Data focused—Apex provides transactional access to the database, allowing you to roll back operations.
  • Easy to use—Apex is based on familiar Java idioms.
  • Easy to test—Apex provides built-in support for unit test creation, execution, and code coverage. Salesforce ensures that all custom Apex code works as expected by executing all unit tests prior to any platform upgrades.
  • Versioned—Custom Apex code can be saved against different versions of the API.

Question 2

Apex is like other object-oriented programming languages because it supports these language constructs:

Answer 2

• Classes, interfaces, properties, and collections (including arrays).
  
  • Object and array notation.
  • Expressions, variables, and constants.
  • Conditional statements (if-then-else) and control flow statements (for loops and while loops).

Question 3

Apex is NOT like other object-oriented programming languages in that it supports:

Answer 3

• Cloud development as Apex is stored, compiled, and executed in the cloud.
  
  • Triggers, which are similar to triggers in database systems.
  • Database statements that allow you to make direct database calls and query languages to query and search data.
  • Transactions and rollbacks.
  • The global access modifier, which is more permissive than the public modifier and allows access across namespaces and applications.
  • Versioning of custom code.

Question 4

Is Apex case-sensitive or case-sensitive?

Answer 4

case-INsensitive

Question 5

Apex is one data type specific to Salesforce. What is it?

Answer 5

sObject

Question 6

What data types are supported by Apex?

Answer 6

• A primitive, such as an Integer, Double, Long, Date, Datetime, String, ID, Boolean, among others.
  
  • An sObject, either as a generic sObject or as a specific sObject, such as an Account, Contact, or MyCustomObject__c (you’ll learn more about sObjects in a later unit.)
  • A collection, including:
    
    • A list (or array) of primitives, sObjects, user defined objects, objects created from Apex classes, or collections
    • A set of primitives
    • A map from a primitive to a primitive, sObject, or collection
  • A typed list of values, also known as an enum
  • User-defined Apex classes
  • System-supplied Apex classes

Question 7

Why is creating a List easier than creating an Array?

Answer 7

Lists don’t require you to determine ahead of time how many elements you need to allocate.

Question 8

Name a benefit of using Apex classes.

Answer 8

Code reuse. Class methods can be called by triggers and other classes.

Question 9

Why is Anonymous Apex a handy tool?

Answer 9

Allow you to run lines of code on the fly and is a handy way to invoke Apex, especially to test out functionality. Debug logs are generated as with any other Apex execution.

Question 10

Before you can insert a Salesforce record, you must …

Answer 10

…create it in memory first as an sObject.

Ex: Account acct = new Account();

Question 11

How many ways can you add fields to an sObject, and what does the syntax look like?

Answer 11

1. through a constructor
Account acct = new Account(Name='Acme', Phone='(415)555-1212', NumberOfEmployees=100);

2. using dot notation 
Account acct = new Account();
acct.Name = 'Acme';
acct.Phone = '(415)555-1212';
acct.NumberOfEmployees = 100;

Question 12

Is dot notation available when working with a generic sObject?

Answer 12

No, because a generic sObject doesn’t know what it is, so there are no properties accessible.

But, you can cast the generic sObject as a specific sObject to access its properties, e.g.:
// Cast a generic sObject to an Account
Account acct = (Account)myGenericSObject;
// Now, you can use the dot notation to access fields on Account
String name = acct.Name;
String phone = acct.Phone;

Question 13

Describe how creating generic sObjects is different from creating specific sObjects.

Answer 13

Generic sObjects can only be created through the newSObject() method. Also, the fields can only be accessed through the put() and get() methods.

Question 14

To retrieve a record, you have to use what?

Answer 14

SOQL - Salesforce Object Query Language

Question 15

To insert an sObject as a record, you have to use what?

Answer 15

DML - Data Manipulation Language

Question 16

What does DML provide?

Answer 16

Straightforward way to manage records by providing simple statements to insert, update, merge, delete and restore (undelete) records.

Question 17

How is Apex DML different from other programming languages?

Answer 17

Other programming languages require additional setup to connect to data sources, but Apex DML allows quick access to perform operations on SF records because Apex is data focused.

Question 18

What does the “merge” DML statement do?

Answer 18

Merges up to 3 records of the same sObject into one record, Deletes the others, and re-parents any related records.

Question 19

How would you retrieve the ID of a newly created record in Salesforce?

Answer 19

On insert, the ID is automatically returned to the sObject variable used for insert, so it’s immediately accessible.

Question 20

What is the max number of DML statements per Apex transaction?

Answer 20

150

Question 21

If you don’t specify a field when doing an “upsert” statement, what field is used by default?

Answer 21

The sObject’s Id.

Question 22

What fields can be used during an “upsert” statement to identify records?

Answer 22

For custom objects, the Id field or any other field marked as an external ID.
For standard objects, the Id field and any field that has idLookup property set to True. For example, Email on both Contact and User objects has this property set.

upsert sObjectList Account.Fields.MyExternalId;

Question 23

What happens if multiple matching records are found during an “upsert” statement?

Answer 23

An error is generated and the object record is neither inserted or updated.

Question 24

How many days does a deleted record live in the Recycle Bin?

Answer 24

15 days

Question 25

What is returned when a DML operation fails?

Answer 25

An exception of type DMLException. You can catch exceptions in your code to handle error conditions. ``` try { // This causes an exception because // the required Name field is not provided. Account acct = new Account(); // Insert the account insert acct; } catch (DmlException e) { System.debug('A DML exception has occurred: ' + e.getMessage()); } ```

Question 26

What are the available built-in Database class methods?

Answer 26

* Database.insert() * Database.update() * Database.upsert() * Database.delete() * Database.undelete() * Database.merge()

Question 27

How are the Database methods different from their DML counterparts?

Answer 27

Database methods have an optional allOrNone parameter that allows you to specify whether the operation should partially succeed. Also, the Database class contains methods that aren't provided as DML statements. - Transaction control and rollback - Emptying the Recycle Bin - and methods related to SOQL queries

Question 28

What happens if the allOrNone parameter is set to False in a Database method?

Answer 28

If errors occur on a partial set of records, the successful records will be committed and errors will be returned for the failed records. Also, no exceptions will be thrown with the partial success option.

Question 29

What happens if the allOrNone parameter is set to True in a Database method?

Answer 29

An exception will be thrown if a failure is encountered and none of the records will be successfully saved.

Question 30

What is the default value of the allOrNone parameter on Database methods?

Answer 30

True

Question 31

What is returned when using each of the Database methods?

Answer 31

For create and update, Database.SaveResult. For upsert, Database.UpsertResult. For delete, Database,DeleteResult.

Question 32

What is the syntax for saving something to the Debug log?

Answer 32

System.debug('Text to enter into log' + variable);

Question 33

Why would you use DML over a Database method?

Answer 33

If you want any error that occurs during bulk DML processing to be thrown as an Apex exception that immediately interrupts control by using try...catch blocks. This behavior is similar to the way exceptions are handled in most database procedural languages.

Question 34

Why would you use Database methods over DML?

Answer 34

If you want to allow partial success of a bulk DML operation. If you want to inspect the rejected records and possibly retry the operation. If you want to avoid thrown exceptions and instead take action on successes and failures differently and intentionally.

Question 35

Can you insert records related to existing records?

Answer 35

Yes, if a relationship has already been defined between the two objects, such as lookup or master-detail lookup relationship. ``` Account acct = new Account(Name='SFDC Account'); insert acct; // Once the account is inserted, the sObject will be // populated with an ID. // Get this ID. ID acctID = acct.ID; // Add a contact to this account. Contact mario = new Contact( FirstName='Mario', LastName='Ruiz', Phone='415.555.1212', AccountId=acctID); insert mario ```

Question 36

Can you delete a parent object and its children (cascading deletes) automatically in one DML statement operation?

Answer 36

Yes, as long as each child record can be deleted. Account[] queriedAccounts = [SELECT Id FROM Account WHERE Name='SFDC Account']; delete queriedAccounts;

Question 37

DML operations execute within a ____.

Answer 37

transaction

Question 38

What happens when a DML operation fails?

Answer 38

DML operations execute within a transaction, so if an error occurs during one operation, the entire transaction is rolled back and no data is committed to the database.

Question 39

What are the boundaries of a transaction?

Answer 39

A trigger, a class method, an anonymous block of code, an Apex page, or a custom Web service method. For example, if a trigger or class creates two accounts and updates one contact, and the contact update fails because of a validation rule failure, the entire transaction rolls back and none of the accounts are persisted in Salesforce.

Question 40

When SOQL is embedded in Apex, it is referred to as ____.

Answer 40

inline SOQL

Question 41

Can you do a "SELECT *" in SOQL?

Answer 41

No, which is dumb.

Question 42

Do you have to specify the Id field in a SOQL query?

Answer 42

No, if more fields are being retrieved. If Id is the only field you're trying to retrieve, then Yes, you have to specify it.

Question 43

What is the syntax for using a variable within a SOQL statement?

Answer 43

Field=:variable e.g. String targetDepartment = 'Wingo'; Contact[] techContacts = [SELECT FirstName,LastName FROM Contact WHERE Department=:targetDepartment];

Question 44

How can you retrieve child records related to a parent record in a SOQL query?

Answer 44

Use an inner query for the child records. The FROM clause of the inner query runs against the relationship name, rather than a Salesforce object name. e.g. SELECT Name, (SELECT LastName FROM Contacts) FROM Account WHERE Name = 'SFDC Computing' e.g. accessing the related records in Apex: Account[] acctsWithContacts = [SELECT Name, (SELECT FirstName,LastName FROM Contacts) FROM Account WHERE Name = 'SFDC Computing']; // Get child records Contact[] cts = acctsWithContacts[0].Contacts; System.debug('Name of first associated contact: ' + cts[0].FirstName + ', ' + cts[0].LastName);

Question 45

What happens when using SOQL in a "for" loop?

Answer 45

Records are retrieved using efficient chunking with calls to the query and queryMore methods of the SOAP API. By using SOQL for loops, you can avoid hitting the heap size limit. SOQL for loops iterate overall of the sObject records returned by a SOQL query. e.g. The syntax is either: for (variable : [soql_query]) { code_block } OR for (variable_list : [soql_query]) { code_block } Both variable and variable_list must be of the same type as the sObjects that are returned by the soql_query. It is preferable to use the sObject list format of the SOQL for loop as the loop executes once for each batch of 200 sObjects. Doing so enables you to work on batches of records and perform DML operations in batch, which helps avoid reaching governor limits.

Question 46

What is an unordered collection of elements that does not contain duplicates and is therefore often used to store ID values since they are always unique?

Answer 46

Set

Question 47

What is an ordered collection of elements that work similar to a traditional array?

Answer 47

List

Question 48

What is a collection of key-value pairs?

Answer 56

Code that is exposed via SOAP or REST web services.

Question 57

Describe how Email Services are invoked.

Answer 57

Code that is setup to process inbound email.

Question 58

Describe how Visualforce or Lightning Pages are invoked.

Answer 58

Visualforce controllers and Lightning components can execute Apex code automatically or when a user initiates an action, such as clicking a button. Lightning components can also be executed by Lightning processes and flows.

Question 59

When do Triggers execute?

Answer 59

Before or after database actions: - before insert, update or delete - after insert, update, delete or undelete

Question 60

What are the two limits you will probably be most concerned with?

Answer 60

Number of SOQL queries and DML statements.

Question 61

What should always be at the top of test classes?

Answer 61

@isTest

Question 62

What are three reasons to use Asynchronous programming?

Answer 62

1. Processing a very large number of records 2. Making callouts to external web services 3. Creating a better and faster user experience

Question 63

How must future methods be declared?

Answer 63

As static void. They cannot return anything.

Question 64

True or False: You cannot pass objects as arguments into future methods.

Answer 64

True

Question 65

What are three drawbacks to using future methods?

Answer 65

1. You can't track execution because no Apex job ID is returned. 2. Parameters must be primitive data types, arrays of primitive data types, or collections of primitive data types. Future methods can't take objects as arguments. 3. You can't chain future methods and have one call another.

Question 66

What are the different types of Asynchronous Apex?

Answer 66

1. Future Methods 2. Batch or Scheduled Apex 3. Queueable Apex

Question 67

What are three drawbacks to using batch or scheduled apex/the batchable interface?

Answer 67

1. Troubleshooting can be troublesome. 2. Jobs are queued and subject to server availability, which can sometimes take longer than anticipated. 3. Have we talked about limits yet?

Question 68

Queuable Apex provides what benefits to future methods?

Answer 68

1. Non-primitive types. Classes can accept parameter variables of non-primitive data types, such as sObjects or custom Apex types. 2. Monitoring - When you submit your job, a jobId is returned that you can use to identify the job and monitor its progress. 3. Chaining jobs - You can chain one job to another job by starting a second job from a running job. Chaining jobs is useful for sequential processing.

Question 69

What is the Apex Flex Queue?

Answer 69

Eliminated limitation of five concurrent batches in 2015 and allows developers to monitor and manage the order of queued jobs.

Quickly add lots of functionality to a page

Question 82

What do fine-grained components allow you to do?

Answer 82

Give you more control over specific details of a page.

Question 83

What does a Standard List Controller do?

Answer 83

Allows you to create VisualForce pages that can display or act on a set of records. Provides many powerful, automatic behaviors such as querying for records of a specific object and making the records available in a collection variable, as well as filtering and pagination through the results.

Question 84

What are static resources?

Answer 84

Static resources allow you to upload content that you can reference in a Visualforce page. Resources can be archives (such as .zip and .jar files), images, stylesheets, JavaScript, and other files.

What does CDN stand for?

Answer 85

Content Distribution Network

Question 86

What are custom controllers?

Answer 86

Contain custom logic and data manipulation that can be used by a VF page. For example, a custom controller can retrieve a list of items to be displayed, make a callout to an external web service, validate and insert data, and more—and all of these operations will be available to the Visualforce page that uses it as a controller.

Question 87

When would you choose to use a custom controller instead of a standard controller?

Answer 87

When you want to override existing functionality, customize the navigation through an application, use callouts or Web services, or if you need finer control for how information is accessed for your page, Visualforce lets you take the reigns

Question 88

Can you use a custom controller and a standard controller together at the same time?

Answer 88

No

Question 89

Answer 102

English-based searches on Account, Contact, Lead, and User

Question 103

What does the Query Optimizer do?

Answer 103

Evaluates SOQL queries and SOSL searches. It routes queries to the appropriate indexes. Looks at every incoming query and assigns it a cost value for each potential query path that it identifies. Then uses costs to determine which execution plan to use.

Question 104

Fields that are automatically indexed include:

Answer 104

Id, Name, OwnerId, CreatedDate, SystemModStamp, Record Type, Master-Detail Fields, Lookup Fields, Unique Fields, and Exernal Id fields

Answer 106

No, just SOQL

Question 107

Included in Lightning Flow are two point-and-click automation tools: Process Builder, which lets you build processes, and Cloud Flow Designer, which lets you build flows. To sum up the differences:

Answer 107

Lightning Flow is the name of the product. Process Builder and Cloud Flow Designer are the names of the tools. Use Process Builder to make processes; use Cloud Flow Designer to make flows.

Question 108

Use Process Builder when you need to start a behind-the-scenes business process automatically. Processes can start when:

Answer 108

A record is created A record is updated A platform event occurs

Question 109

Use Cloud Flow Designer to:

Answer 109

Automate a guided visual experience. Add more functionality for a behind-the-scenes process than is available in Process Builder. Build the more complex functionality in the Cloud Flow Designer. Then call the resulting flow from the process. Start a behind-the-scenes business process when a user clicks something, like a button.

Question 110

Use Apex when

Answer 110

you need more functionality than is available in Process Builder or Cloud Flow Designer. Build the more complex functionality as invocable Apex methods. Then call the resulting Apex as an Apex action in the process or as an Apex element in the flow.

Question 111

Every process consists of

Answer 111

a trigger, at least one criteria node, and at least one action

Question 112

Process Builder is

Answer 112

a point-and-click tool that lets you easily automate if/then business processes and see a graphical representation of your process as you build.

Question 113

A PB can be triggered by one of 2 events:

Answer 113

Only when a record is created | Anytime a record is created or edited

Question 114

In PB, how many criteria can you set up?

Answer 114

As many as your heart desires

Question 115

In PB, in each criteria node, you can:

Answer 115

Set filter conditions. Enter a custom formula. Like in validation rules, the formula must resolve to true or false. Opt out of criteria and always execute the associated actions.

Question 116

In PB, with scheduled actions, you can schedule actions based on either:

Answer 116

A specific date/time field on the record that started the process. For example, a month before an account's service contract expires. The time that the process ran. For example, 3 days from now.

Question 117

In a scheduled action, at the specified time, Salesforce does what?

Answer 117

makes sure that the associated criteria node still evaluates to True

Question 118

In PB, these are actions you can configure:

Answer 118

Create records. Update the record that started the process or any related record. Submit that record for approval. Update one or more related records. Send emails using a specified email template. Post to a Chatter feed.

Question 119

Process Builder can automate a few kinds of business processes. The main difference is the trigger: when the process starts.

Answer 119

Type Process Starts When Record Change A record is created or edited Invocable It’s called by another process Platform Event A platform event message is received

Question 120

Process Builder can’t:

Answer 120

``` Post to a community feed Submit a related record for approval Delete records Create a bunch of records and associate them with each other Perform complex logic ```

Question 121

Flow variables come in 4 types:

Answer 121

Variable A single value “Hello World”, true, 6 sObject Variable A set of field values for a single record Rating, ID, and Name for an account Collection Variable Multiple values of the same data type [1, 2, 3, 5, 8, 13] sObject Collection Variable A set of field values for multiple records that have the same object Rating, ID, and Name for multiple accounts

Question 122

Triggers are active by default when created.

Answer 122

True

Question 123

To prevent saving records in a trigger,

Answer 123

call the addError() method on the sObject in question.

Question 124

When users enter a term in the search field

Answer 124

(1), the search engine breaks up the search term into tokens (2). It matches those tokens to the record information stored in the search index (3), ranks the associated records by relevance (4), and returns the results that users have access to (5).

Question 125

The search index also provides the opportunity to introduce relevance ranking into the mix. This is our secret sauce to find and rank the records users are looking for. What are the special ingredients?

Answer 125

A dash of search term frequency, order, and uniqueness; a sprinkle of record activity; a spoonful of access permissions; and a handful of other factors.

Question 126

three things about helpers:

Answer 126

A component’s helper is the appropriate place to put code to be shared between several different action handlers. A component’s helper is a great place to put complex processing details, so that the logic of your action handlers remains clear and streamlined. Helper functions can have any function signature. That is, they’re not constrained the way that action handlers in the controller are. (Why is this? Because you are calling the helper function directly from your code. By contrast, the framework calls action handlers via the framework runtime.) It’s a convention and recommended practice to always provide the component as the first parameter to helper functions.

Question 127

What is $A?

Answer 127

It’s a framework global variable that provides a number of important functions and services.

Question 128

What is $A?

Answer 128

It’s a framework global variable that provides a number of important functions and services.

Question 129

There are two types of events,

Answer 129

component and application

Question 130

What is LDS?

Answer 130

Lightning Data Service

Question 131

What is LDS?

Answer 131

Lightning Data Service

Question 132

The Checkpoint Inspector has two tabs: Heap and Symbols.

Answer 132

Heap—Displays all objects present in memory at the line of code where your checkpoint was executed. Symbols—Displays all symbols in memory in tree view.

Question 133

Test methods...

Answer 133

You can save up to 6 MB of Apex code in each org. Test classes annotated with @isTest don’t count toward this limit. Even though test data rolls back, no separate database is used for testing. As a result, for some sObjects that have fields with unique constraints, inserting duplicate sObject records results in an error. Test methods don’t send emails. Test methods can’t make callouts to external services. You can use mock callouts in tests. SOSL searches performed in a test return empty results. To ensure predictable results, use Test.setFixedSearchResults() to define the records to be returned by the search.

Question 134

You’ll typically use Asynchronous Apex for

Answer 134

callouts to external systems, operations that require higher limits, and code that needs to run at a certain time

Question 135

The key benefits of asynchronous processing include:

Answer 135

User efficiency Scalability Higher limits

Question 136

Asynchronous Apex flavors, description and common scenarios, GO:

Answer 136

Future Methods: Run in their own thread, and do not start until resources are available. Web service callout. Batch Apex: Run large jobs that would exceed normal processing limits. Data cleansing or archiving of records. Queueable Apex: Similar to future methods, but provide additional job chaining and allow more complex data types to be used. Performing sequential processing operations with external Web services. Scheduled Apex: Schedule Apex to run at a specified time. Daily or weekly tasks.

Question 137

How are Asynchronous Apex governor limits different?

Answer 137

Number of SOQL queries doubles from 100 to 200 | Total heap size and CPU time are similarly larger

Question 138

To make a Web service callout to an external service or API, you create an Apex class with a future method that is marked with

Answer 138

(callout=true) ``` public class SMSUtils { // Call async from triggers, etc, where callouts are not permitted. @future(callout=true) public static void sendSMSAsync(String fromNbr, String toNbr, String m) { String results = sendSMS(fromNbr, toNbr, m); System.debug(results); } ```

Question 139

Testing future methods is a little different than typical Apex testing. To test future methods,

Answer 139

enclose your test code between the startTest and stopTest test methods. The system collects all asynchronous calls made after the startTest. When stopTest is executed, all these collected asynchronous processes are then run synchronously. You can then assert that the asynchronous call operated properly.

Question 140

Test code cannot actually send callouts to external systems, so you’ll have to ‘mock’ the callout for test coverage

Answer 140

@isTest global class SMSCalloutMock implements HttpCalloutMock { global HttpResponse respond(HttpRequest req) { // Create a fake response HttpResponse res = new HttpResponse(); res.setHeader('Content-Type', 'application/json'); res.setBody('{"status":"success"}'); res.setStatusCode(200); return res; } }

Question 141

True or False: Future methods can’t be used in Visualforce controllers in getMethodName(), setMethodName(), nor in the constructor.

Answer 141

True

Question 142

True or False: You can call a future method from another future method.

Answer 142

False

Question 143

How many future calls can you make per Apex invocation?

Answer 143

50

Question 144

1 Why would a developer use Test. startTest( ) and Test.stopTest( )? A. To avoid Apex code coverage requirements for the code between these lines B. To start and stop anonymous block execution when executing anonymous Apex code C. To indicate test code so that it does not Impact Apex line count governor limits. D. To create an additional set of governor limits during the execution of a single test class.

Answer 144

D. To create an additional set of governor limits during the execution of a single test class.

Question 145

The Limits methods returns what?

Answer 145

the specific limit for the particular governor, such as the number of calls of a method or the amount of heap size remaining. For example, getCallouts returns the number of callouts to an external service that have already been processed in the current context, while getLimitCallouts returns the total number of callouts available in the given context.

Question 146

How many times can startTest() and stopTest() be called per method?

Answer 146

Each test method is allowed to call this method only once.

Answer 152

A. Case Layout | B. Account Layout

Question 153

What is the Metadata API used for?

Answer 153

Use Metadata API to retrieve, deploy, create, update or delete customization information, such as custom object definitions and page layouts, for your organization. This API is intended for managing customizations and for building tools that can manage the metadata model, not the data itself. To create, retrieve, update or delete records, such as accounts or leads, use data SOAP API or REST API.

Question 154

What tools are used to access the functionality of the Metadata API?

Answer 154

Force.com IDE (Eclipse) and the Ant Migration Tool (Ant tools)

Question 155

What permissions are needed to access the Metadata API?

Answer 155

Users with the Modify Metadata permission can update metadata (including Apex) through Metadata API even if they don’t also have the Modify All Data permission. Metadata API is used for deployments using change sets, the Ant Migration Tool, or the Salesforce CLI. Users must have the permission that enables use of the feature supported by the metadata they’re trying to modify. They must also have the permission that enables their deployment tool. The Modify Metadata permission doesn’t impact direct customization of metadata using Setup UI pages, because those pages don’t use Metadata API for updates.

Question 156

The deploy() and retrieve() calls are used primarily for the following development scenarios:

Answer 156

Development of a custom application (or customization) in a sandbox organization. After development and testing is completed, the application or customization is then deployed into a production organization using Metadata API. Team development of an application in a Developer Edition organization. After development and testing is completed, you can then distribute the application via Lightning Platform AppExchange.

Answer 200

A. When a Visualforce page needs to replace the functionality of a standard controller. C. When a Visualforce page should not enforce permissions or field-level security.

Question 201

What is a custom controller?

Answer 201

A custom controller is an Apex class that implements all of the logic for a page without leveraging a standard controller. Use custom controllers when you want your Visualforce page to run entirely in system mode, which does not enforce the permissions and field-level security of the current user.

Question 202

What is a controller extension?

Answer 202

``` A controller extension is an Apex class that extends the functionality of a standard or custom controller. Use controller extensions when: You want to leverage the built-in functionality of a standard controller but override one or more actions, such as edit, view, save, or delete. You want to add new actions. You want to build a Visualforce page that respects user permissions. Although a controller extension class executes in system mode, if a controller extension extends a standard controller, the logic from the standard controller does not execute in system mode. Instead, it executes in user mode, in which permissions, field-level security, and sharing rules of the current user apply. ```

Question 301

Are tests automatically run in non-production orgs?

Answer 301

By default, no tests are run in a deployment to a non-production organization, such as a sandbox or a Developer Edition organization. To specify tests to run in your development environment, set a testLevel deployment option. For example, to run local tests in a deployment and to exclude managed package tests, set testLevel on the DeployOptions object to TestLevel.RunLocalTests. Next, pass this object as an argument to the deploy() call as follows. The RunLocalTests test level is enforced regardless of the contents of the deployment package. In contrast, tests are executed by default in production only if your deployment package contains Apex classes or triggers. You can use RunLocalTests for sandbox and production deployments.

Question 302

What can you use to run unit test methods?

Answer 302

To verify the functionality of your Apex code, execute unit tests. You can run Apex test methods in the Developer Console, in Setup, in the Force.com IDE, or using the API.

Question 303

Testing Best Practices:

Answer 303

Unit tests must cover at least 75% of your Apex code, and all of those tests must complete successfully. Note the following. When deploying Apex to a production organization, each unit test in your organization namespace is executed by default. Calls to System.debug are not counted as part of Apex code coverage. Test methods and test classes are not counted as part of Apex code coverage. While only 75% of your Apex code must be covered by tests, don’t focus on the percentage of code that is covered. Instead, make sure that every use case of your application is covered, including positive and negative cases, as well as bulk and single records. This approach ensures that 75% or more of your code is covered by unit tests. Every trigger must have some test coverage. All classes and triggers must compile successfully. If you are running many tests, consider the following: In the Force.com IDE, increase the Read timeout value for your Apex project. See https://developer.salesforce.com/page/Apex_Toolkit_for_Eclipse for details. In the Salesforce user interface, test the classes in your organization individually, instead of using the Run All Tests button to run them all together.
