Pairwise testing is a testing technique used to efficiently cover combinations of input values while minimizing the number of test scenarios.

The principle involves selecting pairs of input values so that every possible combination is tested while reducing the overall number of tests. Therefore, it is necessary to choose combinations of input values so that every possible pair is covered. This method leverages the idea that errors associated with interactions between two factors are often critical and will be revealed in tests that examine these combinations.

There are several tools and methodologies that can help implement this technique, one of which is available to you below. More
