The test matrix shows the interrelationship between functional events and tests. The completed test matrix defines the conditions that must be tested during the test process to verify the proper functioning of the application system. It does not represent the totality of testing because there may be types of tests that verify the structure of the system, such as verifying the correct use of program statements that are not included in the test matrix.
