Explain all the factors of Testability.
Answers
Testability a property applying to empirical hypothesis involves 2 components. The effort and effectiveness of software tests depends on numerous factors including: Properties of the software requirements . Properties of the software itself (such as size complexity and testability)
i think it will help u
Answer:
The test ability of software components (modules, classes) is determined by factors such as:
Controllability: The degree to which it is possible to control the state of the component under test (CUT) as required for testing.
Observability: The degree to which it is possible to observe (intermediate and final) test results.
Isolateability: The degree to which the component under test (CUT) can be tested in isolation.
Separation of concerns: The degree to which the component under test has a single, well defined responsibility.
Understandability: The degree to which the component under test is documented or self-explaining.
Automatability: The degree to which it is possible to automate testing of the component under test.
Heterogeneity: The degree to which the use of diverse technologies requires to use diverse test methods and tools in parallel.
