ISTBQ MCQ Questions


Q. We split testing into distinct stages primarily because:

  1. Each test stage has a different purpose.
  2.  It is easier to manage testing in stages.
  3. We can run different tests in different environments.
  4. The more stages we have, the better the testing.

Show Answer

Ans. 1. Each test stage has a different purpose.

 

Q. Which of the following is likely to benefit most from the use of test tools providing test capture and replay facilities?

  1. Regression testing
  2. Integration testing
  3. System testing
  4. User acceptance testing

Show Answer

Ans. 1. Regression testing 

 

Q.Which of the following statements is NOT correct?

  1. A minimal test set that achieves 100% LCSAJ coverage will also achieve 100% branch coverage.
  2. A minimal test set that achieves 100% path coverage will also achieve 100% statement coverage.
  3. A minimal test set that achieves 100% path coverage will generally detect more faults than one that achieves 100% statement coverage.
  4. A minimal test set that achieves 100% statement coverage will generally detect more faults than one that achieves 100% branch coverage

Show Answer

Ans. 4. A minimal test set that achieves 100% statement coverage will generally detect more faults than one that achieves 100% branch coverage

 

Q. Error guessing:

  1. supplements formal test design techniques.

Q. Which of the following is NOT true of test coverage criteria?

  1. Test coverage criteria can be measured in terms of items exercised by a test suite.
  2. A measure of test coverage criteria is the percentage of user requirements covered
  3. A measure of test coverage criteria is the percentage of faults found
  4. Test coverage criteria are often used when specifying test completion criteria

Show Answer

Ans. 3. A measure of test coverage criteria is the percentage of faults found 

 

Q. In prioritizing what to test the most important objective is to:

  1. find as many faults as possible
  2. test high-risk areas.
  3. obtain good test coverage.
  4. test whatever is easiest to test.

Show Answer

Ans. 2. test high-risk areas. 

 

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

  1. System tests are often performed by independent teams.
  2. Functional testing is used more than structural testing.
  3. Faults found during system tests can be very expensive to fix.
  4. End-users should be involved in system tests.

Show Answer

Ans. 4. End-users should be involved in system tests.

 

Q. Which of the following is false?

  1. Incidents should always be fixed.
  2. An incident occurs when expected and actual results differ.
  3. Incidents can be analyzed to assist in test process improvement.
  4. An incident can be raised against documentation.

Show Answer

Ans 1. Incidents should always be fixed.

 

Q. Enough testing has been performed when:

  1. time runs out.
  2. the required level of confidence has been achieved.
  3. no more faults are found.
  4. the users won’t find any serious faults.

Show Answer

Ans. 2. the required level of confidence has been achieved. 

 

Q. Which of the following is NOT true of incidents?

  1. Incident resolution is the responsibility of the author of the software under test.
  2. Incidents may be raised against user requirements.
  3. Incidents require investigation and/or correction.
  4. Incidents are raised when expected and actual results differ

Show Answer

Ans. 1. Incident resolution is the responsibility of the author of the software under test.

  3. A fault need not affect the reliability of a system.
  4. Undetected errors may lead to faults and eventually to incorrect behavior.

Show Answer

Ans. 2. A system is necessarily more reliable after debugging for the removal of a fault.
