ISTQB - Exam 2

Which statement about testing is true?

• Testing can only be done by an independent test team.

• Testing is started after the code is written so that we have a system with which to work.

• Testing is started as early as possible in the life cycle.

• Testing is most economically done at the end of the life cycle.

The risk of an undetected defect ...

• … does not influence testing in any way.

• … has no influence on the specification of the test cases.

• … has no influence on the prioritization of the tests.

• … has influence on test comprehensiveness and intensity.

During testing, …

• … all parts of the system should be tested with the same intensity, because defects can be everywhere.

• … the user interface should primarily be tested, because failures in it are most annoying for the customer.

• … system parts where failures may cause great risks should be tested most intensively.

• … data base access should be tested intensively, in order to prevent wrong data and inconsistencies an the database.

Which of the following is a true general testing principle?

• Testing can prove that there are no defects.

• If testing shows no defects, then the system is useful.

• Defects are evenly distributed throughout the system.

• Repeating the same test cases over again in new versions of the software finds less and less defects.

Which of the following alternatives describes the fundamental test process?

• Planning, follow up and control, analysis and specification, design and implementation, execution and evaluating exit criteria, reporting and test closure activities.

• Strategic planning, specification, implementation, test environment implementation, execution and checking, follow-up and reporting.

• Planning and control, evaluation, implementation, execution, retest and regression test, test closure activities, evaluating exit criteria and reporting.

• Planning and control, test analysis, test design, test implementation, test execution, test completion

Which of the following statement is true?

• Tests are best designed by the person who wrote the Software Quality Engineering

• Component testing is best done by developer, system testing must be done by a group independent from developers.

• Independence assures effective testing.

• A certain degree of independence is often more effective in finding defects

Which goal is usually not part of component testing?

• Testing correct interactions between component.

• Testing completeness of the component’s functionality.

• Testing correct functionality of the component.

• Testing robustness of the component.

Which of the following is true of the V-model ….

• … it specifies the test techniques to be used

• … it only models the test phase

• … it includes the verification of design

• … it only states that testing against user requirement

Which option best describes objectives for test levels with a life cycle model? …

• Objectives are the same for each test level.

• Each level has objectives specific to that level.

• The objectives of a test level don’t need to be defined in advance.

• Objectives should be generic for any test level.

Testing according to the V-model has the following fundamental principles

• There must a least be the following test levels: Component testing, integration testing, system testing and acceptance testing.

• The model is only useful for large critical software projects where there is one delivery only.

• For every development level, there must be a corresponding test level.

• For every development level, there must be a corresponding test level. For every test level, early test design should be implemented.
