Orthogonal Array Testing. What is orthogonal array testing oats. Orthogonal array testing is a systematic and statistical way of a black box testing technique used when number of inputs to the application under test is small but too complex for an exhaustive testing.
Oat is a systematic and statistical approach to pairwise interactions. Orthogonal array testing is a black box testing technique which is a systematic statistical way of software testing. Orthogonal arrays oa are two dimensional arrays i e factors levels by choosing any two columns in the array provides even distribution of all the pair wise combinations.
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.
What is orthogonal array testing oats. It is done by deriving small sets of test cases from a large number of scenarios and also by giving precedence to factors and levels that appear multiple times in the combinatorial outputs. Orthogonal array testing is a systematic and statistical way of a black box testing technique used when number of inputs to the application under test is small but too complex for an exhaustive testing. It is used when the number of inputs to the system is relatively small but too large to allow for exhaustive testing of every possible input to the systems.
