  • 2. 

    Enough testing has been performed when:

    • Time runs out.

    • The required level of confidence has been achieved

    • No more faults are found.

    • The users won’t find any serious faults.

    Correct Answer
    A. The required level of confidence has been achieved
  • 3. 

    In prioritising what to test, the most important objective is to:

    • Find as many faults as possible

    • Test high risk areas.

    • Obtain good test coverage

    • Test whatever is easiest to test.

    Correct Answer
    A. Test high risk areas.
  • 4. 

    We split testing into distinct stages primarily because:

    • Each test stage has a different purpose.

    • It is easier to manage testing in stages.

    • We can run different tests in different environments

    • The more stages we have, the better the testing.

    Correct Answer
    A. Each test stage has a different purpose.
  • 5. 

    How would you estimate the amount of re-testing likely to be required?

    • Metrics from previous similar projects

    • Discussions with the development team

    • Time allocated for regression testing

    • A & b

    Correct Answer
    A. A & b
  • 6. 

    Error guessing:

    • Supplements formal test design techniques.

    • Can only be used in component, integration and system testing.

    • Is only performed in user acceptance testing.

    • Is not repeatable and should not be used.

    Correct Answer
    A. Supplements formal test design techniques.
  • 7. 

    Which of the following characterises the cost of faults?

    • They are cheapest to find in the early development phases and the most expensive to fix in the latest test phases.

    • They are easiest to find during system testing but the most expensive to fix then.

    • Faults are cheapest to find in the early development phases but the most expensive to fix then.

    • Although faults are most expensive to find during early development phases, they are cheapest to fix then.

    Correct Answer
    A. They are cheapest to find in the early development phases and the most expensive to fix in the latest test phases.
  • 8. 

    Which of the following requirements is testable?

    • The response time shall be less than one second for the specified design load.

    • The system shall be built to be portable.

    Correct Answer
    A. The response time shall be less than one second for the specified design load.
  • 9. 

    Analyse the following highly simplified procedure:Ask: “What type of ticket do you require, single or return?”IF the customer wants ‘return’Ask: “What rate, Standard or Cheap-day?”IF the customer replies ‘Cheap-day’Say: “That will be £11:20”ELSESay: “That will be £19:50”ENDIFELSESay: “That will be £9:75”ENDIFNow decide the minimum number of tests that are needed to ensure that allthe questions have been asked, all combinations have occurred and allreplies given.

    Which of the following is false?

    • Incidents should always be fixed.

    • An incident occurs when expected and actual results differ.

    • Incidents can be analysed to assist in test process improvement.

    • An incident can be raised against documentation.

    Correct Answer
    A. Incidents should always be fixed.
  • 11. 

    Which of the following is NOT true of incidents?

    • Incident resolution is the responsibility of the author of the software under test.

    • Incidents may be raised against user requirements.

    • Incidents require investigation and/or correction.

    • Incidents are raised when expected and actual results differ.

    Correct Answer
    A. Incident resolution is the responsibility of the author of the software under test.
  • 12. 

    Which one of the following statements about system testing is NOT true?

    • System tests are often performed by independent teams.

    • Functional testing is used more than structural testing.

    • Faults found during system tests can be very expensive to fix.

    • End-users should be involved in system tests.

    Correct Answer
    A. End-users should be involved in system tests.
  • 13.

  • 14. 

    Which of the following statements is NOT correct?

    • A minimal test set that achieves 100% LCSAJ coverage will also achieve 100% branch coverage

    • A minimal test set that achieves 100% path coverage will also achieve 100% statement coverage.

    • A minimal test set that achieves 100% path coverage will generally detect more faults than one that achieves 100% statement coverage.

    • A minimal test set that achieves 100% statement coverage will generally detect more faults than one that achieves 100% branch coverage.

    Correct Answer
    A. A minimal test set that achieves 100% statement coverage will generally detect more faults than one that achieves 100% branch coverage.
  • 15. 

    Which of the following is false?

    • In a system two different failures may have different severities.

    • A system is necessarily more reliable after debugging for the removal of a fault.

    • A fault need not affect the reliability of a system.

    • Undetected errors may lead to faults and eventually to incorrect behaviour.

    Correct Answer
    A. A system is necessarily more reliable after debugging for the removal of a fault.
  • 16. 

    Which of the following is true of the V-model?
