Q

True or False? Testing should be prioritized based on the risk exposure.

A

True - Risk exposure is the probability of an adverse event occurring multiplied by the consequences. If this value is high, it should be tested first.

Q

True or False? Good test cases ideally map back to requirements and have their own identifiers.

A

True

19
Q

True or False? Severity reflects the customer impact of the error.

A

True

20
Q

What is not included in a test incident report description?

Attempts to repeat
Expected results
Priority of the defect
Date and time

A

Priority of the defect - Defect priority is not set by the tester who finds the problem but is a management decision.

Recommendations for improving the testing process
Summary of what was tested
Comprehensive assessments
Evaluation

A

Recommendations for improving the testing process

Q

True or False? Having a list of effort and resources needed to perform tasks is not required when creating a test schedule.

A

False

26
Q

True or False? One should utilize an estimate of POFA (pass of first attempt) to estimate overall system testing time.

A

True

27
Q

True or False? Identifying all of the testing tasks requires thoroughly understanding the requirements.

A

True

28
Q

Which of the following is not a reason for inaccurate estimates?

True
False

A

False

30
Q

Which of the following is not a curve used to analyze software readiness?

Remaining defects in the software
Mean time to failure
Number of failures per unit of time
Failure intensity

A

Remaining defects in the software

31
Q

True or False? High severity errors implies high priority errors.

A

False
