Software testing can provide objective, independent information about the quality of software and the risk of its failure to a user or sponsor.

Software testability is the degree to which a software artifact (e.g. a software system, module, requirement, or design document) supports testing in a given test context. . If the testability of an artifact is high, then finding faults in the system (if any) by means of testing is easi
Unit testing, a.k.a. component or module testing, is a form of software testing by which isolated source code is tested to validate expected behavior. [1] Unit testing describes tests that are run at the unit-level to contrast testing at the integration or system level.
Metamorphic testing (MT) is a property-based software testing technique, which can be an effective approach for addressing the test oracle problem and test case generation problem. The test oracle problem is the difficulty of determining the expected outcomes of selected test cases or to determine whether the actual outputs agree with the ...
