Which of the following statements CORRECTLY describes a role of impact analysis in Maintenance Testing?

• Impact analysis is used when deciding if a fix to a maintained system is worthwhile

• Impact analysis is used to identify how data should be migrated into the maintained system

• Impact analysis is used to decide which hot fixes are of most value to the user

• Impact analysis is used to determine the effectiveness of new maintenance test cases

Which of the following statements BEST compares the purposes of confirmation testing and regression testing?

• The purpose of regression testing is to ensure that all previously run tests still work correctly, while the purpose of confirmation testing is to ensure that any fixes made to one part of the system have not adversely affected other parts

• The purpose of confirmation testing is to check that a previously found defect has been fixed, while the purpose of regression testing is to ensure that no other parts of the system have been adversely affected by the fix

• The purpose of regression testing is to ensure that any changes to one part of the system have not caused another part to fail, while the purpose of confirmation testing is to check that all previously run tests still provide the same results as before

• The purpose of confirmation testing is to confirm that changes to the system were made successfully, while the purpose of regression testing is to run tests that previously failed to ensure that they now work correctly

Which of the following statements about test types and test levels is CORRECT?

• Functional and non-functional testing can be performed at system and acceptance test levels, while white-box testing is restricted to component and integration testing

• Functional testing can be performed at any test level, while white-box testing is restricted to component testing

• It is possible to perform functional, non-functional and white-box testing at any test level

• Functional and non-functional testing can be performed at any test level, while Whitebox testing is restricted to component and integration testing

Given that the testing being performed has the following attributes:

· based on interface specifications;

· focused on finding failures in communication;

· the test approach uses both functional and structural test types.

Which of the following test levels is MOST likely being performed?

• Component integration testing

• Acceptance testing

• System testing

• Component testing

Given the following statements about the relationships between software development activities and test activities in the software development lifecycle:

1. Each development activity should have a corresponding testing activity.

2. Reviewing should start as soon as final versions of documents become available.

3. The design and implementation of tests should start during the corresponding development.

activity

4. Testing activities should start in the early stages of the software development lifecycle.

Which of the following CORRECTLY shows which are true and false?

• True – 1, 2; False – 3, 4

• True – 2, 3; False – 1, 2

• True – 1, 2, 4; False – 3

• True – 1, 4; False – 2, 3

Which of the following should NOT be a trigger for maintenance testing?

• Decision to test the maintainability of the software

• Decision to test the system after migration to a new operating platform

• Decision to test if archived data is possible to be retrieved

• Decision to test after “hot fixes”

Which one of the following is the BEST definition of an incremental development model?

• Defining requirements, designing software and testing are done in phases where in each phase a piece of the system is added

• A phase in the development process should begins when the previous phase is complete

• Testing is viewed as a separate phase which takes place after development has been

  completed

• Testing is added to development as an increment

Which one of the following is TRUE?

• The purpose of regression testing is to check if the correction has been successfully implemented, while the purpose of confirmation testing is to confirm that the correction has no side effects

• The purpose of regression testing is to detect unintended side effects, while the purpose of confirmation testing is to check if the system is still working in a new environment

• The purpose of regression testing is to detect unintended side effects, while the purpose of confirmation testing is to check if the original defect has been fixed

• The purpose of regression testing is to check if the new functionality is working, while the purpose of confirmation testing is to check if the original defect has been fixed

Which of the following statements comparing component testing and system testing is TRUE?

• Component testing verifies the functionality of software modules, program objects, and classes that are separately testable, whereas system testing verifies interfaces between

  components and interactions between 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 or use cases

• Component testing only focuses on functional characteristics, whereas system testing

  focuses on functional and non-functional characteristics

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

How can white-box testing be applied during acceptance testing?

• To check if large volumes of data can be transferred between integrated systems

• To check if all code statements and code decision paths have been executed

• To check if all work process flows have been covered

• To cover all web page navigations
