Incremental integration testing
Incremental integration testing is continuous testing of an application as new functionality is recommended. This may require that various aspects of an application's functionality are independent enough to work separately, before all parts of the program are completed, or that test drivers are developed as needed.
Incremental testing may be performed by programmers, software engineers, or test engineers.
Exhaustive Testing
Executing the program with all possible combinations of values for program variables. Feasible only for small, simple programs.
Functional Testing
(1) Testing that ignores the internal mechanism or structure of a system or component and focuses on the outputs generated in response to selected inputs and execution conditions.
(2) Testing conducted to evaluate the compliance of a system or component with specified functional requirements and corresponding predicted results.
(3) Application of test data derived from the specified functional requirements without regard to the final program structure. Also known as black-box testing.
Interface Testing
Testing conducted to evaluate whether systems or components pass data and control correctly to one another. Contrast with testing, unit; testing, system.
Mutation Testing
A testing methodology in which two or more program mutations are executed using the same test cases to evaluate the ability of the test cases to detect differences in the mutations.
Operational Testing
Testing conducted to evaluate a system or component in its operational environment. Contrast with testing, development; testing, acceptance;
Parallel Testing
Testing a new or an altered data processing system with the same source data that is used in another system. The other system is considered as the standard of comparison.
