Set at least 2 values for each parameter
Pairwise Test Generator is an online tool that efficiently generates combination test cases for multiple parameters. Even when testing all combinations is impractical, the pairwise method (All-Pairs method) covers all 2-way combinations while significantly reducing the number of test cases. Empirically, most bugs occur in combinations of two parameters, enabling highly efficient bug detection.
The pairwise method (All-Pairs method) is a technique that ensures all pairs of parameters (2-way combinations) are included in the test cases. Since most bugs occur in combinations of two factors, it achieves high bug detection rates with fewer test cases.
The reduction rate varies depending on the number of parameters and values, but typically 70-95% reduction is expected. For example, with 4 parameters each having 3 values, full combinations would be 81 cases, but pairwise can reduce this to about 9-12 cases.
2-way coverage means that for any two parameters, all value combinations are included at least once in the test cases. This tool always guarantees 100% 2-way coverage.
Web Testing includes browser, OS, screen size, etc. Mobile Testing includes device, OS, network conditions, etc. API Testing includes HTTP methods, authentication types, response formats, etc. - common parameters for each testing type.
The pairwise method guarantees 2-way combinations only, so specific 3-way or higher combinations are not guaranteed. However, since 3-way+ bugs are statistically rare, 2-way coverage is sufficient in most cases.
