Orthogonal Array Example. Three two level factors l8. If we have 3 parameters each can have 3 values then the possible number of tests using conventional method is 3 3 27 while the same using oat it boils down to 9 test cases.
Orthogonal array testing helps to maximize test coverage by pairing and combining the inputs and testing the system with comparatively less number of test cases for time saving. 100 orthogonal array testing implies 100 pairwise testing. Due to this the factors can be evaluated independently of each other.
Parameter tested 3 times 9 required runs for this orthogonal array.
The given l9 orthogonal array assess result of test cases as follows. Parameter tested 3 times 9 required runs for this orthogonal array. Eleven two level factors l16. The given l9 orthogonal array assess result of test cases as follows.
