Unit 1: Introduction Flashcards
True or False? Verification focuses on if the requirements are meeting customer needs and are what the customer wants.
False
True
False
Verification looks at building the product right given the assumption that the requirements are correct. Validation looks at building the right product to bring value and meet the customer’s requirements.
A team of testers are testing software against a given set of requirements. The requirements have already approved by the customer. Is the testing team performing verification or validation of the software, or neither?
Neither
Validation
Verification
Verification
Verification looks at building the product right given the assumption that the requirements are correct. Validation looks at building the right product to bring value and meet the customer’s requirements.
How often does testing happen in agile development?
Weekly
At least daily
Monthly
At the end of the project
At least daily
Agile testing follows the theme of continuous integration where code is integrated and tested at least daily.
What is the correct phase order in test driven development?
Green, Refactor, Red
Red, Green, Refactor
Green, Red, Refactor
Red, Refactor, Green
Red, Green, Refactor
The red phase is where a small test is written that defines the behavior needed from the code. Then, in the green phase, code is written to ensure the failing test from the previous phase passes. In the refactor phase, the quality of code is improved while all tests are still passing.
What is the objective of system testing?
To test only nonfunctional requirements
To test only functional requirements
To test whether the customer accepts the software
To test both functional and nonfunctional requirements
To test both functional and nonfunctional requirements
System testing is when other components, such as hardware and software integration testing (functional requirements) and aspects such as stress, usability, and performance testing (nonfunctional requirements) are tested.
Question 4
What is the objective of unit level testing?
To verify that an individual developer’s unit is tested properly
To validate that an individual developer’s unit is tested properly
To test whether units of software can work together to perform high level functions and features
To test both functional and nonfunctional requirements
To verify that an individual developer’s unit is tested properly
Which group of people should perform system testing?
An independent test team
Developers
A combination of developers and testers
An integration team
An independent test team
What is(are) the primary objective(s) of system testing?
To find important problems and predict reliability
To find a required number of problems
To predict reliability
To perform an exhaustive search for all the problems
To find important problems and predict reliability
When is a reasonable time to stop testing?
Once it is demonstrated that the important requirements are met
No testing of requirements is needed.
Once it is demonstrated that at least one requirement is met
Once we have met our test objectives.
Once we have met our test objectives.
Why do defects cluster?
Because there are no changes happening to the codebase
Defects are actually distributed evenly across every thousand lines of code.
Because a developer intentionally includes them to be found by testers
Because of the complexity of code, programmer skill, etc.
Because of the complexity of code, programmer skill, etc.
True or False? Reliability is the probability that a software program operates for some given time period without software error.
True
True or False? Testing is the examination of the behavior of the program by executing it on all of the possible data sets.
False
True or False? Model based testing requires modeling the behavior of the system.
True
True or False? Certified software testers should ensure that the deliverables they provide meet the highest professional standards possible.
True
In test driven development, what is the equivalent of gathering requirements during the software development process? Gathering tester's input Gathering test objectives Gathering possible test designs Gathering sample test cases
Gathering test objectives
