testing

Test-stage discipline: /testing:plan (coverage gaps, test plans), /testing:write (TDD authoring), /testing:run-e2e (live E2E and smoke checks), /testing:diagnose (failing-test root cause, with a fix-until-green workflow across files), /testing:audit (can't-fail test audit with a fail-closed gate), /testing:cleanup (rewrite, quarantine, or delete low-value tests behind a mutation gate), /testing:setup, and an opt-in hook that flags edits that weaken tests.

Plugin testing from marketplace melodic-software in melodic-software/claude-code-plugins. Commands read from the repo's manifest — today.

This plugin runs code on your machine — its hooks fire automatically on events like tool use. The exact commands are listed below; read them before installing.

What it installs

Skills (9)

  • audit

    Find tests that cannot fail or check little: assertion-free, tautological, vacuous, recomputed or mock-only expectations, asserts that never run, snapshot-only oracles, change detectors, retry-masking runner configs (Playwright, pytest, Vitest, Jest), stray `test.only`. JS/TS, Python, C#, Bash, Powe

  • check-visual-parity

    Hold a UI pixel-for-pixel steady through a change: PNG screenshots of the listed states before the first edit (baseline), then again at each green checkpoint, with differing pixels counted against pixel_tolerance (compare). Never edits a baseline. Use when: a plan phase has a Parity contract line, a

  • cleanup

    Clean up low-value tests in one folder, or plan a repo as per-project batches: reads /testing:audit findings, its judge pass's FLAG verdicts and the tests the user names as flaky, has a fresh-context classifier pick quarantine, rewrite, delete, merge or keep per test, rewrites by default, and delete

  • diagnose

    Diagnose and fix failing tests. Failure classification, root-cause analysis (never retry blindly), then the reproduce → isolate → fix → retest → regression loop. Use when: 'why does this fail', 'this test is failing', 'fix the failing tests', 'why is this test flaky', visible test failures, stack tr

  • plan

    Analyze code changes and produce a test plan. Classify changed files by required test type, identify coverage gaps, and prioritize by regression risk. Use when: 'test plan', 'what needs testing', 'where are the coverage gaps', 'what should I test here', after /implementation:implement completes, or

  • run-e2e

    When the bundled run skill resolves in this session, prefer it to launch the app for a quick look; this skill for evidenced verification flows. End-to-end live app verification. Check prerequisites, start the app, drive UI/API flows, and capture evidence (screenshots, responses, logs); includes a no

  • setup

    Configure the testing plugin's can't-fail checks for this repository. check prints the resolved testing config cascade, which test-lint rules the repo's lint config turns on per language (a missing one is a finding), an optional instruction line to paste, and any test glob the shipped test-weaken ho

  • test-value

    What makes a test worth keeping: where each expected value must come from, when call-count and database checks are legitimate, and the can't-fail and change-detector taxonomy keyed to testing:audit rule ids. Use when writing, reviewing or fixing tests, or asking 'is this test worth keeping', 'where

  • write

    Write and place tests across all ecosystems. TDD cadence (Red→Green→Refactor in vertical slices), test naming, test-type selection (including property, characterization and old-versus-new tests), project placement, and fixture patterns. Use when: the user wants tests written or coverage added for co

Subagents (4)

  • green-fixer

    Fixes one group of failing tests for the testing:fix-until-green workflow, editing only the files the workflow assigns, with Read, Edit and a shell. Dispatched by that workflow; not intended for direct ad-hoc use.

  • green-runner

    Runs one test or check command for the testing:fix-until-green workflow and returns its failures as structure, with a shell only: no file reads, and no edits outside the throwaway worktree of its base re-run stage. Dispatched by that workflow; not intended for direct ad-hoc use.

  • green-verifier

    Checks a testing:fix-until-green round's diff for test weakening and, on the final pass, re-runs the command, with Read and a shell: no edits. Dispatched by that workflow; not intended for direct ad-hoc use.

  • test-judge

    Judges where each given test block's expected value came from (FLAG, PASS or UNKNOWN) with quoted evidence and a proposed diff it never applies, with Read, Grep and Glob only. Dispatched by /testing:audit --judge only; not intended for direct ad-hoc use.

claude

Code-review toolkit: nine agents, read-only over the reviewed code, plus orchestration skills for the quality gate and fan-out, a pull-request change digest with an interactive view (/review:explain-change), a merge-risk rating with a demote-only flag (/review:merge-risk), a fan-out sweep workflow (/review:fanout-sweep), and CI lane commands (/review:code-review, /review:security-review) for org reusable workflows.

discovery

claude

Discovery before changes: explore the local codebase, run multi-source external research, and reconstruct why a past decision was made from evidence outside the code. Each dispatches a subagent by default so the reading stays out of the main thread, with source tiers, falsification, recency gates and a coverage ledger, and persists EXPLORE.md / RESEARCH.md / INTENT.md handoff artifacts. A research sweep workflow (/discovery:research-sweep) backs deep research with adversarial claim verification.

planning

claude

Pre-implementation planning pipeline: chart a too-big, foggy effort as a decision map, diverge on candidate approaches, lock product intent and the engineering contract, route resolved domain language to the domain-driven-design glossary steward, explore the design space, stress-test adversarially, and produce a structured implementation plan with an approval gate, with an opt-in multi-angle plan panel workflow (/planning:plan-panel).
