Test design


In software engineering, test design is the act of creating and writing test suites for testing a software.

Test design could require all or one of:

Well designed test suites will provide for an efficient testing. The test suite will have just enough test cases to test the system, but no more. This way, there is no time lost in writing redundant test cases that would unnecessarily consume time each time they are executed. In addition, the test suite will not contain brittle or ambiguous test cases.

Entire test suites or test cases exposing real bugs can be automatically generated by software using model checking or symbolic execution. Model checking can ensure all the paths of a simple program are exercised, while symbolic execution can detect bugs and generate a test case that will expose the bug when the software is run using this test case.

However, as good as automatic test design can be, it is not appropriate for all circumstances. If the complexity becomes too high, then human test design must come into play as it is far more flexible and it can concentrate on generating higher level test suites.
