--- name: pypict-skill description: "Pairwise test generation" risk: safe source: "https://github.com/omkamal/pypict-claude-skill/blob/main/SKILL.md" date_added: "2026-02-27" --- # Pypict Skill ## Overview Pairwise test generation ## When to Use Design a small test matrix covering every pair of values across discrete factors, when exhaustive combinations are too costly and pairwise coverage is appropriate. ## Procedure 1. Define factors, permitted values and real invalid-combination constraints. 2. Inspect an actual installed pairwise generator and its supported input format; this entrypoint does not bundle a Python package or executable. 3. Generate candidate rows and independently enumerate covered valid value pairs. Missing pairs must remain visible; constraints must not be invented to hide them. 4. Convert rows into tests with expected behavior, not just input combinations. For three binary factors, this illustrative matrix covers all two-factor pairs: ```json [[0,0,0],[0,1,1],[1,0,1],[1,1,0]] ``` Pair coverage is not correctness or coverage of three-way interactions. Add known boundary, authorization and failure cases separately. ## Example **User request:** > Use @pypict-skill for this task: Pairwise test generation. ## Limitations - Use this skill only when the task clearly matches the scope described above. - Do not treat the output as a substitute for environment-specific validation, testing, or expert review. - Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
