Orthogonal array testing

The Orthogonal Array (OA) based testing is a systematic, statistical way of testing the software. Orthogonal Arrays could be applied in User Interface testing, System Testing, Regression Testing, Configuration Testing and Performance Testing.

Benefits: 1. Provides uniformly distributed coverage of the test domain. 2. Concise test set with fewer test cases is created. 3. All pair-wise comibnations of test set created. 4. Arrives at complex combinations of all the variables. 5. Simpler to generate and less error prone than test sets created manually. 6. Reduces testing cycle time.
