1)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.

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

Regression testing
Integration testing
System testing
User acceptance testing

3)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

4) Analyze 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
