Software Testing Glossary

Test is considered to be failed if the actual result does not match the expected result.

Testing by simulating failure modes or actually causing failures in a controlled environment.

Deviation of a component or system performance, operation or resultfrom the expected one.

It is physical or functional manifestation of a failure type.

Systematic approach to determination and analyzing of risks of identification of possible types of failures and attempt to prevent them.

Extension of FMEA; in addition to the basic FMEA it includes an analysis of criticality, which used to display the probability of types of failures with respect to the criticality of their consequences. The result reflects the type of failure with a high probability and criticality of the consequences, allowing corrective action, where they will have the greatest value.

It is the ratio of the number of failures in this category to a given unit of measure.

Test result, which has reported an error, but in fact there is no defect in the object of testing.

Test result, which was unable to determine the presence of a software bug really existing in the object of testing.

Element of a comprehensive test strategy that enables the tester to concentrate on the manner in which the application under test is able to handle exceptions.
