Correct Answer: - Each test stage has a different purpose.

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

Correct

Well Done... 🙂

Incorrect

Correct Answer: - Regression testing 

Which of the following statements is NOT correct?

Correct

Well Done.... 🙂

Incorrect

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

Which of the following requirements is testable?

Correct

Well Done... 🙂

Incorrect

Correct Answer: - The response time shall be less than one second for the specified design load.

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”

ELSE

Say: “That will be £19:50”

ENDIF ELSE

Say: “That will be £9:75”

ENDIF

Now decide the minimum number of tests that are needed to ensure that all the questions have been asked, all combinations have occurred and all replies given.
