behaviour, this is called an error a fault a failure a defect a mistake.

The difference between re-testing and regression testing is: re-testing is running a test again; regression testing looks for unexpected sideeffects re-testing looks for unexpected sideeffects; regression testing is repeating those tests re-testing is done after faults are fixed; regression testing is done earlier re-testing uses different environments, regression testing uses the same environment re-testing is done by developers, regression testing is done by independent testers.

Documentation Standard? Test items (i.e. software versions) What is not to be tested Test environments Quality plans Schedules and deadlines.
Could reviews or inspections be considered part of testing? no, because they apply to development documentation no, because they are normally applied before testing no, because they do not apply to the test documentation yes, because both help detect faults and improve quality yes, because testing includes all non-constructive
activities.
