Python unit testing per-framework wrappers: 4 skills (pytest-tests, unittest-tests, doctest-tests, nose2-tests) plus 1 A2 agent (python-test-author) that authors one unit test per spec by detecting pytest / unittest / doctest / nose2 from pyproject.toml / setup.cfg / tox.ini / existing test files. Per-framework lifecycle (configure / run / mock / coverage / CI).
Configures and runs async Python tests with pytest-asyncio: installs the plugin, selects asyncio_mode (auto vs strict), scopes event loops (function/class/module/session), writes async fixtures with @pytest_asyncio.fixture, mocks coroutines with AsyncMock, and tests FastAPI (httpx.AsyncClient + ASGITransport) and aiohttp (aiohttp_client fixture) applications. Use when a Python project contains async def test_ functions, FastAPI/aiohttp endpoints, or any asyncio-based code that needs pytest integration.
Configures and runs pytest - the de facto Python test framework with fixture-based dependency injection (`@pytest.fixture` with scopes module/session/function), parametrize for table-driven tests (`@pytest.mark.parametrize`), markers (`@pytest.mark.skip` / `xfail` / `slow`), `conftest.py` for shared fixtures, plugin ecosystem (pytest-cov, pytest-asyncio, pytest-mock, pytest-xdist), `--lf`/`--ff` for fail-loop, coverage gating. Use when working with Python and needing the modern test framework.
Configures and runs Python's stdlib unittest - TestCase + setUp/tearDown lifecycle hooks, assertion catalog (assertEqual / assertRaises / assertIn / assertAlmostEqual), unittest.mock module (Mock / MagicMock / patch / patch.object / patch.dict), test discovery via `python -m unittest discover`, subTest for parametrized cases, expectedFailure decorator. Use when constrained to stdlib-only (no pip install) or migrating legacy unittest codebases.
Configures and runs Python''''s stdlib doctest - embeds executable test cases in docstrings using `>>>` Python interactive prompt convention; supports `# doctest: +ELLIPSIS` / `+NORMALIZE_WHITESPACE` / `+SKIP` directives; integrates with pytest via `--doctest-modules` flag; runs as `python -m doctest module.py -v`. Use for self-documenting reference implementations + simple smoke-test coverage embedded in API docs.
Configures and runs nose2 - successor to nose (the original Python test discovery library, end-of-life 2015) and an alternative to pytest's discovery model; supports plugin architecture, layers (per-test-class setUp/tearDown shared across modules), parameterized tests via `nose2.tools.params`, multi-process parallelism via mp plugin. Use when migrating from legacy nose1 codebases or when the team prefers nose2's plugin model over pytest.

A rigorously curated quality-engineering plugin marketplace for Claude Code. 77 plugins, 695 components, every one rating-gated before merge.
d6 floordocs/REVIEWER_TRAINING.mdSee Quality bar and docs/REVIEWER_CHECKLIST.md.
The marketplace ships three kinds of building block:
qa-api-testing, qa-load-testing). You install only the plugins your
stack needs.great-expectations,
oauth-flow-test-author). Claude loads a skill when your request matches
its trigger; you can also ask for it by name.schema-diff-reviewer reviews a migration diff and returns a findings
table). An agent may preload one or more skills to do its work.Installed components stay dormant until a matching task comes up, so adding a plugin doesn't add noise — it adds capability that activates on demand.
/plugin marketplace add testland/qa
/plugin install <plugin-name>@testland-qa
For example:
/plugin install qa-data-quality@testland-qa
/plugin marketplace add https://github.com/testland/qa
git clone https://github.com/testland/qa ~/.claude/marketplaces/testland-qa
Before you install: plugins run inside your Claude Code session and ship agent instructions and tool wrappers. Anthropic doesn't vet marketplace contents — review a plugin's components before installing it into a sensitive project. Every component here is rating-gated (see Quality bar), but you remain in control of what runs.
New to the marketplace? Install one or two plugins for your role rather than everything — components activate on demand, so a focused set keeps things sharp.

Once a plugin is installed, its skills and agents are available to Claude
Code — invoke them by describing the task in plain language. Example with
qa-data-quality:
/plugin install qa-data-quality@testland-qa
great-expectations skill scaffolds an ExpectationSuite + Checkpoint and
wires the results into a CI gate.schema-diff-reviewer agent returns a Critical / Warning / Info findings
table covering breaking-vs-additive changes and downstream impact.Each plugin's README.md lists its skills and agents and what each one does.
