Why Orthogonal Array Is Used?

Orthogonal array testing is a black box testing technique that is a systematic, statistical way of software 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.

Why orthogonal array is used in Lean?

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. ... In such cases, we can use the Orthogonal Array testing method.

What is meant by orthogonal array?

In mathematics, an orthogonal array is a "table" (array) whose entries come from a fixed finite set of symbols (typically, {1,2,...,n}), arranged in such a way that there is an integer t so that for every selection of t columns of the table, all ordered t-tuples of the symbols, formed by taking the entries in each row ...
