rogerchappel Write Tests
When To Use
Use this skill when a user asks for new tests, bug reproduction coverage, or fixture-backed regression checks.
Inputs
Use the target source file, existing test style, package scripts, and fixture data already present in the repo.
Side Effects
Limit edits to tests, fixtures, and tiny support helpers unless the user asks for implementation changes.
Approval
Ask before installing dependencies, changing snapshots broadly, or running commands that write outside the repository.
Examples
- Add regression tests for this parser bug.
- Cover the CLI error path with fixtures.
Validation
Add fixtures first, cover edge cases, and keep tests runnable offline. Run the narrow test command before wider validation. Verify by running the affected test command and recording the result.
