UiPath Associate - intro to dev role

Question 1

Business Process parts

Answer 1

Usually diagram
Definition: A process is a set of interrelated or interacting activities that transforms inputs into outputs.
Components of a process:
Inputs - the data that goes in the process;
Process Flows - the sequences of sub-processes or activities undertaken in the process;
Source Applications - the applications or systems used to perform the sub-processes or activities of the process;
Outputs - the result generated by the process;
Things to remember: The outputs of a process can serve as inputs for other processes.

Question 2

Procedure v process

Answer 2

There are a lot of things that are missing from the definition of a standard process, such as time constraints, dependency on other processes, variations and how resources are assigned. This is where procedures come into play.
Usually complex document

A procedure explains:

who is responsible for each part of the process
when each part of the process needs to occur
how to handle exceptions
the specifications applicable to each part of the process.

Question 3

Good candidate for RPA

Answer 3

Rule-based
Automatable and/or repetitive process

Manual & non-repetitive: the process steps are performed by humans and can be different every time the process is executed
Manual & repetitive: the steps in the process are performed by the user, and at least some of them are the same every time
Semi-automated & repetitive: some of the repetitive steps have already been automated (using macros, Outlook rules, and so on)
Automated: there are processes that have been already automated using other technologies than RPA

Standard input
Stable

Question 4

Factors that impact automation conplexity

Answer 4

Number of Screens
Types of Applications
Business Logic Scenarios
Types and Number of Inputs

Question 5

Assessing automation potential

Answer 5

Non rpa Processes where change is frequent, the system environment is volatile, and multiple manual (even non-digital) actions are required
Semi auto Processes that can be broken down into steps that can be clearly automated, and steps that need to stay manual (such as validations or usage of physical security tokens)
High cost rpa Processes that are rather digital and can be automated, but use some technologies that are complex (such as OCR) or require advanced programming skills
0 touch auto Processes that are digital and involve a highly static system and process environment, so that they can be easily broken into instructions and simple triggers can be defined

Question 6

Six stages in RPA implementations

Answer 6

Use photo

Prepare RPA, Solution Design, Build RPA Solution, Test RPA Solution, Stabilize RPA, Constant Improvement.

Question 7

The Academy Ecosystem

Answer 7

offers several platforms to help you succeed as an RPA Developer: Connect!, Marketplace, Community Forum and Academy

Question 8

Automation First.

Answer 8

is a three-pronged approach: A Robot for Every Person, Open and Free Collaboration, Robots Learn Skills

Question 9

Variables

Answer 9

Variables are containers that can hold multiple data entries

Name - specific, Camel convention
Type - int, general, boolean etc. Type usually assigned by default
Default value -
Scope - level of the workflow, local v global

Creating
Properties, designer(ctrl k) and variable panel

Question 10

Arguments

Answer 10

Variables that travel between workflows

In, out, in/out

Question 11

Variable data types

Answer 11

Borrowed from vb.net

Numeric - int, long and double
Boolean - true / false
Date and time - date time / time span
String - text
Collection - aray(same var same size), list(same var dynamic size), dictionary (key, value different data type)
Generic value - text, numbers, dates and arrays

As a good case practice, arrays are used for defined sets of data (for example, the months of the year or a predefined list of files in a folder). Whenever the collection might require size changes, a List is probably the better option.

Question 12

Elements of flow control”

Answer 12

order in which individual statements, instructions or function calls are executed or evaluated in a software project

Sequence - process steps flow in a clear succession. Decision trees are rarely used
Flowchart - Use flowcharts when decision points and branching are needed in order to accommodate complex scenarios, workarounds and decision mechanisms
State Machine
Global Exception Handler

Question 13

The control flow statements

Answer 13

If/else
Loops
Switch

Question 14

If/else

Answer 14

two courses of action that are not arbitrary, an If statement will most likely be used
True = then, false=else, 2 outcomes. If /else sequence = flow switch in flowchart activity

Conditions can be used from VB net

Question 15

Loop

Answer 15

Do while - It executes a specific sequence while a condition is met. The condition is evaluated After each execution of the statements.
While - It executes a specific sequence while a condition is met. The condition is evaluated Before each execution of the statements.
For each - It performs an activity or a series of activities on each element of a collection.

Question 16

String

Answer 16

Strings are the data type corresponding to text. 8 types

Assign can contain many string activities in one string

message. Split(“.”c).First.ToString.Substring(message.LastIndexOf(“author”)):
- v Split(“.”c).First.ToString extracts the first sentence of the String and converts it to a String;
- v Substring(message.LastIndexOf(“author”)) extracts the Substring that is after “author”;

Question 17

Concat (string)

Answer 17

Concatenates the string representations of two specified objects

Expression: String.Concat (VarName1, VarName2)

Question 18

Contains (string)

Answer 18

Checks whether a specified substring occurs within a string. Returns true or false

Expression: VarName.Contains (“text”)

Question 19

Join (string)

Answer 19

Concatenates the elements in a collection and displays them as String

Expression: String.Join(“|”, CollVarName1)

Question 20

IndexOf (string)

Answer 20

Returns the zero-based index of the first occurrence of a character in a String

Expression: VarName1.IndexOf(“a”)

Question 21

Substring (string)

Answer 21

Extracts a substring from a string using the starting index and the length

Expression: VarName1.Substring(startIndex, length)

Question 22

Split (string)

Answer 22

Splits a string into substrings using a given separator

Expression: VarName.Split(“|“c)(index)

Question 23

Replace (string)

Answer 23

Replaces all the occurrences of a substring in a string

Expression: VarName.Replace (“original”, “replaced”)

Question 24

Format (string)

Answer 24

Converts the value of objects to strings (and inserts them into another text)

Expression: String.Format(“{0} is {1}”, VarName1, VarName2)

Question 25

Exists in collection(list)

Answer 25

Indicates whether a given item is present in a given collection by outputting a Boolean as the result. We can use this activity to check whether a list of clients contains a specific name.

Question 26

Clear collection(list)

Answer 26

Clears a specified collection of all items. One possible use is to empty a collection before starting a new phase of a process that will populate it again.

Question 27

Dictionary

Answer 27

Dictionaries (or Dictionary, as you will encounter them) are collections of (key, value) pairs, in which the keys are unique. Think of the Address Book in your mobile phone, where each name has corresponding data (phone number(s), email). 4 methods

The data types for both keys and values have to be chosen when the variable is instantiated. Data types in Dictionaries can be any of the supported variables (including Dictionaries, for example).

The operations that are most often associated with Dictionaries are:
Adding and deleting (key, value) pairs
Retrieving the value associated with a key
Re-assigning new values to existing keys

Question 28

Initialisation of dictionaries and lists

Answer 28

Just like in the example of Lists, Dictionaries have to be initialized. In the following example, the initialization is done inside an ‘Assign’ activity. However, as you may remember from the Lists chapter, it can be done from the Variables Panel.

Question 29

Adding items to dictionaries

Answer 29

VarName.Add(Key, Value) – adds an item to an existing Dictionary. Because Add does not return a value, use the Invoke Code activity.

Question 30

Removing items from dictionar

Answer 30

VarName.Remove(Key) – removes an item from the Dictionary. It can be used in an ‘Assign’ activity.

Question 31

Retrieving items from dictionary

Answer 31

VarName.Item(Key) – returns the Dictionary item by its key
VarName.Count – returns an Int32 value of the number of Dictionary items
VarName.ContainsKey(Key) – checks if the item with the given key exists in the Dictionary and returns a Boolean result
VarName.TryGetValue(Key, Value) – checks if an item with a given key exists in the Dictionary and returns a Boolean result and the value if found

Question 32

RegEx

Answer 32

Regular Expression (REGEX, or regexp) is a specific search pattern that can be used to easily match, locate and manage text. However, creating RegEx expressions may be challenging. 3 methods

UiPath Studio contains a RegEx builder that simplifies the creation of regular expressions.

Typical uses of RegEx include:
Input validation
String parsing
Data scraping
String manipulation

Question 33

Is match (regex)

Answer 33

Indicates whether the specified regular expression finds a match in the specified input string. (Boolean)

Question 34

Matches (regex)

Answer 34

Searches an input string for all occurrences and returns all the successful matches.

Question 35

Replace (regex)

Answer 35

Replaces strings that match a regular expression pattern with a specified replacement string.

Question 36

Enterprise RPA parts

Answer 36

Discovery - SW process (backend) mining, task mining (frontend). Automation hub - idea store, task capture full process chart integrated to automation hub
Build - Studio and StudioX
Run - attended and unattended
Manage - Orchestrator and Cloud platform
Engage - Action Center - robot task handoff to human
Measure - Insights - measurement tool for RPA team and business stakeholders

Question 37

Selectors

Answer 37

A Selector in UiPath Studio is a feature that enables the identification of the User Interface elements through its address and attributes.

Selectors are made of nodes. And each node is made of tags and attributes.

Full selectors - have all window information, useful when switching between windows

Partial selectors - placed in the containers, used on the same window

Wildcards - * replaces several, ? replaces one
Dynamic selectors - ctrl s
Difficult selectors - anchor, relative, visual tree, find children
