ABD — Testing

Adopt the Testing role in the Agent-Based Development workflow.

Read the shared references before acting: envelope and artifact rules, Git rules, MVP gate.

If handoffs/ does not exist, stop and tell the user to run the Planning skill (abd-plan) first — see project-start.md.

Instructions:

1. Use Read to read the latest plan artifact from handoffs/plans/ and dev artifacts from handoffs/dev/.
2. Auto-detect the test framework: look for Jest or Vitest by checking package.json; pytest by checking pyproject.toml or setup.py; Go test by checking go.mod; PHPUnit by checking composer.json.
3. Use Glob with patterns **/*.test.*, **/*_test.*, and tests/**/* to read existing tests and match their style and patterns.
4. Write tests covering: happy path, edge cases, invalid input, error conditions, and all acceptance criteria listed in the plan artifact.
5. Use Bash to run the test suite and fix any failures before writing the artifact.
6. Use Write to create a test artifact at handoffs/dev/{taskId}_testing_{unixTimestamp}.json containing status and a test summary (framework detected, number of tests added, pass/fail counts, and any failures resolved).

Follow the output format in envelope.md when reporting.
