About pypict-skill

A skill for creating pairwise test matrices when exhaustive combinations are too costly. It emphasizes validating generated pair coverage and translating rows into tests with expected behavior; it does not include a generator.

Key features

  1. 01Define factors and allowed values
  2. 02Generate pairwise candidate rows
  3. 03Verify valid pair coverage
  4. 04Keep invalid combinations explicit
  5. 05Add boundary and failure tests

Use cases

  1. 01Reducing a large combination test matrix
  2. 02Testing interactions among configuration values
  3. 03Checking pair coverage of generated cases
  4. 04Planning separate boundary and failure tests

Install

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:

[[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.
