Questions and Answers

1.

We split testing into distinct stages (or test levels) primarily because:
- A.
  
  Each test stage has a different purpose.
- B.
  
  It is easier to manage testing in stages.
- C.
  
  We can run different tests in different environments.
- D.
  
  The more stages we have, the better the testing.
Correct Answer
A. Each test stage has a different purpose.

Explanation
I hope this answer is obvious. B might be true, C isn't relevant, and D is debatable. The reason we have stages like component testing, integration testing, system testing and acceptance testing is because they have different purposes.

- B.
  
  4
- C.
  
  5
- D.
  
  6
Correct Answer
A. 3

Explanation
This looks like a decision coverage question, and I've found that the easiest way to work out decision coverage for a code fragment is to draw a simple flowchart and count the number of paths through it.

3.

Error guessing:
- A.
  
  Supplements formal test design techniques.
- B.
  
  Can only be used in component, integration and system testing.
- C.
  
  Is only performed in user acceptance testing.
- D.
  
  Is not repeatable and should not be used.
Correct Answer
A. Supplements formal test design techniques.

Explanation
Error guessing is clearly a useful technique and by process of elimination, the correct answer should be easy to find.

4.

Which of the following is not true of test coverage criteria?
- A.
  
  Test coverage criteria can be measured in terms of items exercised by a test suite.
- B.
  
  A measure of test coverage criteria is the percentage of user requirements covered.
- C.
  
  A measure of test coverage criteria is the percentage of faults found.
- D.
  
  Test coverage criteria are often used when specifying test completion criteria.
Correct Answer
C. A measure of test coverage criteria is the percentage of faults found.

Explanation
This should be an obvious answer, because "coverage" always relates to how much we have tested (not how many faults we have found).

Rate this question:
5.

Which one of the following statements about system testing is not true?
- A.
  
  System tests are often performed by independent teams.
- B.
  
  Functional testing is used more than structural testing.
- C.
  
  Faults found during system tests can be very expensive to fix.
- D.
  
  End-users should be involved in system tests.
Correct Answer
D. End-users should be involved in system tests.

Explanation
System testing involves testing an integrated system to verify that it meets specified requirements. We don't usually include the end-users in this; they become involved during acceptance testing instead.

Rate this question:
6.

Which of the following is true of the V-model?
- A.
  
  It states that modules are tested against user requirements.
- B.
  
  It only models the testing phase.
- C.
  
  It specifies the test techniques to be used.
- D.
  
  It includes the verification of designs.
Correct Answer
D. It includes the verification of designs.

Explanation
This is a "process of elimination" question.
