Mr. Test has been testing software applications on mobile devices for a period of 5 years. He has a wealth of experience in testing mobile applications and achieves better results in a shorter time than others. Over several months, Mr. Test did not modify the existing automated test cases and did not create any new test cases. This leads to fewer and fewer defects being found by executing the tests. What principle of testing did Mr. Test not observe?
a)
Testing depends on the environment
b)
Exhaustive testing is not possible
c)
Repeating of same tests will not find new defects
d)
Defects cluster together
16.
To answer this question, please use the information contained in the image enclosed.
a)
The statement is true. Any single test case provides 100% statement coverage and therefore 50% decision coverage
b)
The statement is true. Any single test case would cause the outcome of the “if” statement to be either true or false
c)
The statement is false. A single test case can only guarantee 25% decision coverage in this case
d)
The statement is false. The statement is too broad. It may be correct or not, depending on the tested software
17.
Which statement about the relationship between statement coverage and decision coverage is true?
a)
100% decision coverage also guarantees 100% statement coverage
