Online Pairwise Test Cases Generation Tool

Pairwise (a.k.a. all-pairs) testing — is an effective test case generation technique that is based on the observation that most faults are caused by interactions of at most two factors. Pairwise-generated test suites cover all combinations of two therefore are much smaller than exhaustive ones yet still very effective in finding defects.

How to use?

  1. Enter comma separated values in textarea on the left side of the screen.
    For example:
    Chrome, Firefox, Safari
    Windows, Linux, MacOS
    latin, кириллица, 상형 문자, نص عربي

  2. Press "Generate pairs" button.

  3. Generated all-pairs will appear.
    For example:
    Chrome, Windows, latin
    Firefox, Linux, latin
    Safari, MacOS, latin
    Safari, Linux, кириллица
    Firefox, Windows, кириллица
    Chrome, MacOS, кириллица
    Chrome, Linux, 상형 문자
    Firefox, MacOS, 상형 문자
    Safari, Windows, 상형 문자
    Safari, Windows, نص عربي
    Firefox, MacOS, نص عربي
    Chrome, Linux, نص عربي

  4. !IMPORTANT! To exclude, for example, pairs of ("Safari" and "Windows") and ("Safari" and "Linux") in results then don't remove them manually from results — it will be incorrect!
    Enter such comma-separated pairs on each line in "exclude" field instead:
    Safari, Windows
    Safari, Linux

  5. And hit "Generate pairs" button.
