Install with my Agent

Copy this request to your Agent. It includes the canonical Skill page and manifest.

Agent request

Review the Skillstore skill "tdd-pytest" from https://skillstore.io/skills/89jobrien-tdd-pytest.md and its manifest at https://skillstore.io/api/skills/89jobrien-tdd-pytest/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.

Your Agent should still show its plan and request any confirmation required by the security policy.

Test it

Using "tdd-pytest". A developer asks for tests before adding password validation.

Expected outcome:

The skill proposes failing pytest cases for valid passwords, short passwords, missing characters, and empty input before implementation steps.

Using "tdd-pytest". A maintainer asks whether current tests are useful.

Expected outcome:

The skill returns a quality review covering fixture reuse, assertion strength, parametrization opportunities, and missing edge cases.

Using "tdd-pytest". A team asks for a local testing report after a pytest run.

Expected outcome:

The skill outlines a report with pass and fail counts, coverage by module, audit findings, recommendations, and command evidence.

Security Audit

Safe

v7 • 7/5/2026 Open versioned report

All static findings were markdown formatting or pytest documentation false positives, not executable Ruby or shell backtick execution. I found no prompt injection, data exfiltration intent, or malicious behavior in SKILL.md.

False positives ignored

No confirmed security findings were detected by the latest completed static and semantic audit. This does not prove the skill has no side effects.

What You Can Build

Add tests before implementation

Plan failing pytest cases first, then implement only enough behavior to pass them.

Audit an existing test suite

Review pytest files for naming, fixture quality, coverage evidence, and missing edge cases.

Standardize pytest configuration

Create practical pyproject.toml settings for discovery, markers, warnings, and coverage reporting.

Try These Prompts

Start a TDD cycle

Use the tdd-pytest workflow for this Python feature. First propose the smallest failing pytest case, then describe the minimal implementation needed to pass it.

Write targeted tests

Write pytest tests for this behavior. Include normal cases, edge cases, and one failure case. Keep the tests focused and explain why each test exists.

Audit test quality

Audit these pytest tests for clarity, fixture design, parametrization, missing assertions, and coverage gaps. Return prioritized recommendations with file and line references.

Prepare a test report

Summarize the pytest run, coverage results, failures, skipped tests, and recommended fixes in TESTING_REPORT.local.md format. Include command evidence and priority levels.

Best Practices

Write the smallest failing test before changing production code.
Run focused tests first, then run the broader suite with coverage.
Keep reports local and include clear evidence for each recommendation.

Avoid

Writing broad tests that do not verify specific behavior.
Changing implementation before confirming the test fails for the right reason.
Using shared fixtures that hide setup details or make failures unclear.

Frequently Asked Questions

Does this skill run tests automatically?

It documents pytest commands and workflows. Execution depends on the host agent, user permissions, and repository environment.

Does it require uv?

The examples use uv, but the pytest guidance can be adapted to other Python environment tools.

Can it help with async pytest tests?

Yes. The skill includes async test patterns and pytest configuration guidance for event loop behavior.

Can it generate coverage reports?

It guides coverage command selection and report structure. The actual coverage run requires project dependencies to be installed.

Can it review existing tests?

Yes. It can audit naming, fixtures, assertions, parametrization, coverage evidence, and missing cases.

Is it only for unit tests?

No. It can guide unit and integration tests when the expected behavior and test boundaries are clear.
