3What is defect testing? What is the goal?
- AYou expect the system to perform correctly using a given set of
test cases that reflect the system’s expected use. - BGoal: demonstrate that the software meets its requirements

4[blank_start]Verification[blank_end]:
– "Are we building the [blank_start]product right[blank_end]”.
– The software should conform to its specification.

- AVerdadero
- BFalso
15Test Components
› [blank_start]A setup part[blank_end]
– where you initialize the system with the test case, namely the
inputs and expected outputs. › [blank_start]A call part[blank_end]
– where you call the object or method to be tested. › [blank_start]An assertion part[blank_end]
– where you compare the result of the call with the expected result. If the assertion evaluates to true, the test has been successful if false, then it has failed.- AA setup part
- BA call part
- CAn assertion part
16What are test method components? Notice setup, call, assertion parts.
- AYes
- BNo
17In test driven development tests are written before code and ‘passing’ the tests is the critical driver of development.
- AVerdadero
- BFalso
18What is test driven development?
- ATests are written after code and ‘passing’ the tests is the critical driver of development.
- BAn approach to program development in which you inter- leave testing and code development.
- CYou develop code incrementally, along with a test for that increment. You don’t move on to the next increment until the code that you have developed passes its test.
19What are not benefits of Test Driven Development?
- ACode coverage
- BRegression testing
- CSimplified debugging
- DSystem documentation
- EAnalysis testing
- FRemittance testing
20Match TDD benefits:
› [blank_start]Code coverage[blank_end]
– Every code segment that you write has at least one associated test so
all code written has at least one test. › [blank_start]Regression testing[blank_end]
– A regression test suite is developed incrementally as a program is developed.
› [blank_start]Simplified debugging[blank_end]
– When a test fails, it should be obvious where the problem lies. The
newly written code needs to be checked and modified. › [blank_start]System documentation[blank_end]
– The tests themselves are a form of documentation that describe what the code should be doing.- ARegression testing
- BCode coverage
- CSimplified debugging
- DSystem documentation
21Regression testing is testing the system to check that changes have not ‘broken’ previously working code.
- AVerdadero
- BFalso
22Which of the following are true about release testing?
- ARelease testing has to show that the system delivers its specified functionality, performance and dependability, and that it does not fail during normal use.
- BRelease testing is usually a black-box testing process where tests are only derived from the system specification.
- CRelease testing is the process of testing a particular release of a system that is intended for use outside of the development team.
- DRelease testing is usually a white-box testing process where tests are only derived from the system specification.
23What is true about performance testing?
- APart of release testing may involve testing the emergent properties of a system, such as performance and reliability.
- BTests should reflect the profile of use of the system.
- CPerformance tests usually involve planning a series of tests where the load is steadily increased until the system performance becomes unacceptable.
- DStress testing is a form of performance testing where the system is deliberately overloaded to test its failure behaviour.
24The user’s working environment have a major effect on the reliability, performance, usability and robustness of a system.
- AVerdadero
- BFalso
25User or customer testing is a stage in the testing process in which users or customers provide input and advice on system testing
