Purpose

Generate starter unit tests for a small function or module.

Inputs to request

  • Function signature and expected behavior.
  • Test framework and language.
  • Edge cases or error conditions.

Workflow

  1. Identify core behaviors and failure cases from the function signature.
  2. Propose table-driven cases with inputs and expected outputs.
  3. Highlight one edge case and one negative case.
  4. Show how to run the tests.

Output

  • Test case list with rationale.
  • Sample test code snippet for the project test framework.

Quality bar

  • Keep tests deterministic and isolated.
  • Prefer clear assertions over broad snapshots.
