equivalence partitioning









































equivalence partitioning or equivalence class partitioning (ecp) is a software testing technique that divides the input data of a software unit into partitions of equivalent data from which test cases can be derived. in principle, test cases are designed to cover each partition at least once. this technique tries to define test cases that uncover classes of errors, thereby reducing the total number of test cases that must be developed. an advantage of this approach is reduction in the time required for testing software due to lesser number of test cases.
equivalence partitioning
prioritize the test cases so as to increase a test suite's rate of fault detection. test case prioritization techniques schedule test cases so that the test cases that are higher in priority are executed before the test cases that have a lower priority.

bullet::::- general prioritization – prioritize test cases that will be beneficial on subsequent versions









































bullet::::- version-specific prioritization – prioritize test cases with respect to a particular version of the software.

this technique is a hybrid of regression test selection and test case prioritization.
