Chapter 2 Concepts

Question 1

Describe

Test-Driven Development (TDD)

Answer 1

• Directs the coding through test cases
• Tests are written first, then the code is written to satisfy the tests, and then the tests and code are refactored
• Developers are usually doing this kind of testing

2.1.3

Question 2

Describe

Acceptance Test-Driven Development (ATDD)

Answer 2

• Derives tests from acceptance criteria as part of the system design process
• Tests are written before the part of the application is developed to satisfy the tests

2.1.3

Question 3

Describe

Behavior-Driven Development (BDD)

Answer 3

• Expresses the desired behavior of an application with test cases written in a simple form of natural language
• Easy to understand by stakeholders
• Given/When/Then format
• Test cases are translated into executable tests

2.1.3

Question 4

True/False

Can ATDD/TDD/BDD be automated later?

Answer 4

True

Tests may persist as automated tests to ensure the code quality in future adaptions / refactoring

2.1.3

Question 5

What are 5 ways the choice of SDLC impacts testing?

Answer 5

• Scope and timing of test activities (e.g., test levels and test types)
• Level of detail of test documentation
• Choice of test techniques and approach
• Extent of test automation
• Role and responsibilities of a tester

Question 6

Fill-in-the-blank

For every software development ____, there is a corresponding test ____, so that all development activities are subject to quality control

Answer 6

activity

Question 7

When in the SDLC should test analysis and design begin?

Answer 7

Test analysis and design for a given test level begins during the corresponding development phase of the SDLC, so that testing can adhere to the principle of early testing

Question 8

True/False

Test levels can reuse test objectives throughout the SDLC.

Answer 8

False

Different test levels have specific and different test objectives, which allows for testing to be appropriately comprehensive while avoiding redundancy

Question 9

When should testers get involved with testing?

Answer 9

Testers are involved in reviewing work products as soon as drafts of this documentation are available, so that this earlier testing and defect detection can support the shift-left strategy

Question 10

What are the three different kinds of maintenance?

Answer 10

• Corrective
• Adaptive to changes in the environment
• Improving performance, maintainability, etc

2.3

Question 11

What is the scope of maintenance testing?

(There are three aspects.)

Answer 11

• Degree of risk of the change
• Size of the existing system
• Size of the change

2.3

Question 12

What are the four triggers for maintenance testing?

Answer 12

• Modifications (planned enhancements, etc)
• Upgrades
• Migrations
• Retirement

2.3

Question 13

When should Impact Analysis be done and why?

Answer 13

may be done before a change is made, to help decide if the change should be made, based on the potential consequences in other areas of the system.

2.3

Question 14

Testing the changes to a system in production includes which two aspects?

Answer 14

• Success of the implementation of the change
• Checking for possible regressions in parts of the system that remain unchanged
