1. A defect was found during testing. When the network got disconnected while receiving data from a server, the system crashed. The defect was fixed by correcting the code that checked the network availability during data transfer. The existing test cases covered 100% of all statements of the corresponding module. To verify the fix and ensure more extensive coverage, some new tests were designed and added to the test suite.

They require significant maintenance effort for each release

They are used for one release and are then discarded to keep the test set fresh

When they have been baselined and approved

After the first revision

As soon as a draft is available

When the developers have started coding

13. Which of these statements about functional testing is true?

Structural testing is more important than functional testing as it addresses the code.

Functional testing is useful throughout the life cycle and can be applied by business analysts, testers, developers and users

Functional testing is more powerful than static testing as you actually run the system and see what happens

Inspection is a form of functional testing

14. Which testing level is primarily focused on building confidence rather than finding defects?

Unit Testing

Integration Testing

System Testing

Acceptance Testing

15. For which of the following would maintenance testing be used?

Correction of defects during the development phase

Planned enhancements to an existing operational system

Complaints about system quality during user acceptance testing

Integrating functions during the development of a new system

16. Beta testing is

Performed by customers at their own site

Performed by customers at the software developer’s site

Performed by an independent test team

Useful to test software developed for a specific customer or user

17. If you need to add system integration testing as a test level for a particular project, what testing level should it directly follow?

Component

Component integration

System

Acceptance

18. Which of the following is a true statement regarding the process of fixing emergency changes ?

There is no time to test the change before it goes live, so only the best developers should do this work and should not involve testers as they slow down the process

Only retesting of the defect actually fixed should be performed

Retest the changed area and then use risk assessment to decide on a reasonable subset of the whole regression test to run in case other parts of the system have been adversely affected

Always run a full regression test of the whole system in case other parts of the system have been adversely affected

19. Which of the following is the correct list of the triggers for maintenance testing?

A component in production is modified, migrated or retired

A fix has been received for a product that is in development

regression has been discovered in a set of fixes just received from the developer

A new requirement has been received for the software that is currently under test that may result in an architectural change

20. Consider the following statements about maintenance testing

I It requires both re-test and regression test and may require additional new tests.

II It is testing to show how easy it will be to maintain the system.

III It is difficult to scope and therefore needs careful risk and impact analysis.

IV It need not be done for emergency bug fixes.

Which of the statements are true?

I and III

I and IV

II and III

II and IV

21. Which of the following is most correct regarding when functional tests may be executed?

Unit & Integration

Integration & System

System & Acceptance

All Levels

22. Which of the following comparisons of component testing and system testing is true?

Component testing verifies the functioning of software modules, program objects, and classes that are separately testable, whereas system testing verifies interfaces between components and interactions with different parts of the system

Test cases for component testing are usually derived from component specifications, design specifications, or data models, whereas test cases for system testing are usually derived from requirement specifications, functional specifications or use cases

Component testing focuses on functional characteristics, whereas system testing focuses on functional and non-functional characteristics

Component testing is the responsibility of the technical testers, whereas system testing typically is the responsibility of the users of the system

Acceptance testing is always the final test level to be applied

To ensure the overall system has not regressed

To ensure no unauthorized changes have been applied to the system

To assess the scope of maintenance performed on the system
