Coverage Py AnalysisAConfigures coverage.py for Python projects - wires `coverage run` (replacing `python` for instrumentation), enables branch coverage via the `--branch` flag or `branch = True` config, manages the `.coverage` data file (single-process and `combine` for parallel pytest-xdist runs), authors `.coveragerc` with `source` / `omit` / `fail_under`, and emits the format the downstream tool needs (`coverage report` for terminal, `coverage xml` for Cobertura, `coverage html` for human review, `coverage lc...testingpythonjavaVotes: 0GitHub stars: 10
Currents IntegrationAWires Currents.dev cross-run test analytics into a Playwright suite: installs `@currents/playwright`, authors `currents.config.ts` (env-sourced `recordKey` + `projectId`), registers `currentsReporter()`, enables trace/video/screenshot artifacts, and runs via `npx pwc` so per-test traces stream to the Currents dashboard with over-time flakiness, slowest-test, and pass-rate trends. Use when a Playwright suite needs hosted cross-run suite-health analytics; for a static per-run report use extentr...testingtypescriptgoVotes: 0GitHub stars: 10
Jacoco AnalysisAConfigures JaCoCo for JVM projects (Java / Kotlin / Scala / Groovy) - wires the runtime agent via `jacoco-maven-plugin` `prepare-agent`, generates per-build reports (HTML / XML / CSV) via the `report` goal, gates the build via the `check` goal with element / limit / minimum rules, parses the six native counters (instructions, branches, lines, methods, classes, cyclomatic complexity), and converts JaCoCo XML to LCOV / Cobertura when downstream tools need a different format. Use when the JVM bu...testinggojavaVotes: 0GitHub stars: 10
Junit Xml AnalysisAExplains CI test numbers that disagree with what the suite actually did - a 'slowest tests' list dominated by the wrong suite, a release gate or dashboard reading only the summary attributes on the suite element and never the cases below them, or a pass rate that quietly counts skipped tests as passes. Parses JUnit-format XML (the interchange format Jenkins, GitHub Actions, GitLab, Buildkite, and CircleCI all ingest) into per-suite and per-case metrics tables - passed / failed / errored / ski...testingpythonrustVotes: 0GitHub stars: 10
Lcov AnalysisAParses both mainstream coverage interchange formats: LCOV `.info` text files (produced by gcov, llvm-cov, Coverage.py via `py2lcov`, JaCoCo via `xml2lcov`, Devel::Cover, Jest via `lcov` reporter, NYC, and most others) and Cobertura XML (coverage-04.dtd - emitted by JaCoCo, coverage.py `--xml`, Jest's `cobertura` reporter, coverlet, gocover-cobertura; full parser in references/cobertura.md). Extracts per-file line / function / branch metrics from the canonical record keywords (TN/SF/FN/FNDA/FN...testingpythonrustVotes: 0GitHub stars: 10
Test Coverage TargeterABuilds a \"what to test next\" recommendation by combining a coverage report (LCOV / Cobertura / coverage.py JSON / Jest JSON / JaCoCo XML) with the PR's `git diff`, ranking uncovered branches by risk × cost - risk weighted by McCabe cyclomatic complexity and code-churn frequency, cost weighted by the unit-test pyramid layer (unit tests cheaper than integration than E2E). Also carries the coverage debt ledger: a weekly per-file drift report over N historical main runs flagging `falling` (line...testingjavascripttypescriptVotes: 0GitHub stars: 10

Test Management SyncASyncs automated test results into test management tools - TestRail (standalone, `add_run` + batched `add_results_for_cases`), Xray for Jira (JWT auth + `/api/v2/import/execution/*`), and Zephyr Scale (Bearer token + `/testexecutions`) - from CI. The body carries the vendor-independent push-results workflow (map tests to case IDs, open a run / execution / cycle per build, batch results back, close on main only, run as an `if: always()` step) with TestRail as the worked example; full vendor spe...testingpythonbashVotes: 0GitHub stars: 10
Test Run Summary AuthorABuild-an-X workflow that turns a structured test-run artifact (JUnit XML, Allure JSON, TestRail / Xray / Zephyr export) plus optional release context (version, build URL, deploy target) into a narrative markdown summary for release notes, an exec status update, or a stand-up Slack post. Distinct from the per-framework parsers junit-xml-analysis / allure-reports / coverage-diff-reporter, which emit structured tabular reports: this skill takes the same data and writes the human-readable narrati...testingrustgoVotes: 0GitHub stars: 10
Object Model PatternsAPure reference catalog of the canonical object-model architecture patterns for test automation frameworks - Page Object Model (Fowler), Screenplay (Marcano/Palmer/Hill), Component Object, App Actions (Cypress idiom), Service Object, Repository, and Screen Object (the desktop/mobile sibling of Page Object covering Windows UIA, macOS XCTest, Linux AT-SPI, Appium / Espresso) - each with its canonical citation, when-to-use rules, refuse-to-mix anti-patterns, and a worked example. This is the arch...testinggojavaVotes: 0GitHub stars: 10
Test Code ConventionsAPure-reference catalog of test-code conventions: AAA structure (Arrange / Act / Assert), per-test single-responsibility, descriptive naming (`{sut}_{scenario}_{expected}`), assertion specificity, mocking rationale (state vs behavior, fake vs mock), fixture-coupling rules, the magic-number / hard-coded-string anti-patterns, and step design (§11: FIRST principles, step granularity, the mechanical → page → business abstraction layers, the rule-of-three extraction heuristic, declarative phrasing)...testingtypescriptgoVotes: 0GitHub stars: 10
Test Design ScorecardAScores test files 1 to 5 on six design axes (AAA phase separation, single-responsibility, naming, fixture coupling, magic literals, setup time) using explicit per-level anchors that settle what separates a 2 from a 4, then turns the scores into growth-framed feedback and a per-author trend report; the per-PR and per-author rollup examples and trend-reporting conventions live in references/. Owns the scoring and the write-up only: the conventions being scored live in a separate conventions cat...testinggoreactVotes: 0GitHub stars: 10
Test Framework Architecture AuditAAudits an existing test automation framework across eight architecture-tier axes and bands each one PASS, WARN, or FAIL: page-object coverage and purity, base-class inheritance depth, fixture scope and coupling, helper sprawl, naming-convention drift, retry and wait consistency, documented-versus-actual convention drift, and CI integration health. Carries the numeric cut behind every band and labels which cuts are practitioner conventions rather than published standards. Measures the framewor...testingtypescriptgoVotes: 0GitHub stars: 10
Test Framework BlueprintABuild-an-X workflow that takes an SDET from no test suite to a complete framework design in seven steps - inventory the SUT, choose runner + language, directory layout + fixture architecture, object-model decision, test data + mocking wiring, reporting + CI integration, conventions doc + review gates - producing a written framework blueprint (directory tree, fixture list, chosen patterns, CI matrix) plus an implementation order. This is the whole-framework design workflow - not the Step 2 run...testingtypescriptpythonVotes: 0GitHub stars: 10
Test Isolation PatternsAPure reference catalog of test-isolation and fixture-lifecycle patterns - the four-phase test pattern (Meszaros), fixture scope (per-test / per-describe / shared / global), the Fresh-Fixture vs Shared-Fixture trade-off (Fowler), parallel-safety patterns, and cleanup discipline (afterEach / afterAll / tagged-cleanup), plus a pattern-selection guide and a worked leaking-state diagnosis. The database-isolation strategies (transaction-rollback / database-per-worker / template-database) and networ...testinggojavaVotes: 0GitHub stars: 10
Test Suite Health AuditAMeasures an existing test suite's current state on four axes: per-file tier classification (unit / integration / E2E, first match wins), pyramid ratio against whatever target the team already committed to, per-layer flake rate, and defects-caught-per-run-minute ROI per tier, then reduces them to one categorical verdict (Healthy, Needs pruning, Needs refactor, Cannot assess). Reports severity against a target ratio but never prescribes one: choosing the target unit:integration:E2E mix and the ...testingrustgoVotes: 0GitHub stars: 10
Dst Transition ReferenceAPure-reference catalog of Daylight Saving Time (DST) transition patterns and their canonical bug classes. Covers the spring-forward (skipped hour: 02:00 → 03:00 local) and fall-back (repeated hour: 02:00 → 01:00 local) transitions, the historical irregularity of DST (different jurisdictions, transitions on different dates, some regions abolish DST or never adopted it), the IANA timezone database (tz / Olson DB) as the canonical source, and the testable behaviors DST creates (duplicate / missi...testingpythongoVotes: 0GitHub stars: 10
Fake Clock TestingAFake clocks / freeze time in tests across every mainstream runtime: freezegun (Python), Jest fake timers + Sinon @sinonjs/fake-timers (JS/TS), timecop (Ruby), java.time.Clock / InstantSource injection (JVM), .NET TimeProvider / FakeTimeProvider, and libfaketime (LD_PRELOAD for any native binary). Covers the language-agnostic discipline - inject or patch the clock, freeze vs tick vs advance vs set-system-time semantics, teardown so fake clocks never leak between tests - plus the shared anti-pa...testingpythonjavaVotes: 0GitHub stars: 10
Timezone Test Matrix BuilderABuilds a timezone, daylight saving time (DST), and leap year / leap second test matrix from wherever a codebase reads or formats dates and times. Finds time-handling code (grep for datetime / Date / Instant / time.time / timezone), sorts each spot into storage, business-logic, display, cron, or billing, picks the edge cases that matter (DST spring-forward / fall-back, ambiguous local time, leap day Feb 29, ISO 8601 / RFC 3339 round-trip, zone-database updates), and emits per-spot test stubs w...testingpythongoVotes: 0GitHub stars: 10
Go Unit TestsAGo unit testing with the stdlib `testing` package - `func TestXxx(t *testing.T)` convention, the table-driven idiom with `t.Run` subtests, `t.Parallel()`, benchmarks (`BenchmarkXxx` + benchstat), examples (`ExampleXxx`), native fuzzing (`FuzzXxx`, Go 1.18+), coverage (`-cover` / `-coverprofile` + threshold gating), build tags, `t.Helper()` / `t.Cleanup`, and `-race` CI.

Includes framework choice (stdlib `#[test]` is the default; rste...testingrustgoVotes: 0GitHub stars: 10
Js Unit TestsASets up and repairs JavaScript / TypeScript unit tests - a suite that cannot resolve the project's path aliases (`@lib/...` declared in jsconfig or tsconfig), a regression that shipped because the tests asserted too little, or a module dependency that needs mocking, spying, or fake timers. Jest and Vitest as co-primary frameworks: install, config (`jest.config.js` / `vite.config.ts` test block), mocking (`jest.fn`/`jest.mock`/`jest.spyOn`, `vi.fn`/`vi.mock`/`vi.spyOn`, `__mocks__/`, fake time...testingjavascripttypescriptVotes: 0GitHub stars: 10
Jvm Unit TestsAJVM unit testing (Java / Kotlin / Scala / Groovy) with JUnit 5 (Jupiter) as the primary framework - annotations (`@Test` / `@ParameterizedTest` / source providers), lifecycle hooks (`@BeforeAll` / `@BeforeEach`), extension model (`@ExtendWith` + Mockito/Spring), display names, conditional execution, parallel-execution config, JaCoCo coverage, and Maven Surefire / Gradle CI. Includes a per-language framework decision table (Java → JUnit 5, Kotlin → Kotest, Groovy → Spock, Scala → ScalaTest, le...testinggojavaVotes: 0GitHub stars: 10
Dotnet Unit TestsA.NET unit testing (C# / F# / VB.NET) with xUnit.net as the primary framework - `[Fact]` single tests, `[Theory]` + `[InlineData]`/`[ClassData]`/`[MemberData]` parametrization, class and collection fixtures (`IClassFixture` / `ICollectionFixture`), parallel-execution config, `ITestOutputHelper` output, skip/traits filtering, and `dotnet test` CI with trx + coverage. Includes framework choice (xUnit for new projects; match an existing NUnit/MSTest convention detected from csproj PackageReferenc...testinggoc#Votes: 0GitHub stars: 10
Pytest Asyncio PatternsAConfigures 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 in...testingpythongoVotes: 0GitHub stars: 10
Python Unit TestsAPython unit testing with pytest as the primary framework - fixtures (`@pytest.fixture` scopes, `conftest.py`), `@pytest.mark.parametrize` table-driven tests, markers (`skip` / `xfail` / custom with `--strict-markers`), `pyproject.toml` config, mocking via pytest-mock, coverage gating with pytest-cov (`--cov-fail-under`), parallel runs with pytest-xdist, and CI wiring - plus stdlib `unittest` (TestCase, unittest.mock, discovery) and `doctest` (docstring examples, directives) as references.

Chart Render TestsAChart-render regression testing across the three chart-library families - Canvas (Chart.js: locator screenshot snapshot + `canvas.toDataURL()` diff with animations disabled), SVG (D3: `outerHTML` structural snapshot with generated-ID normalization + per-element data-binding tests), and declarative specs (Vega / Vega-Lite: JSON Schema validation + Vega-Lite → Vega compile test). Detects the family from package.json imports (chart.js / d3 / vega-lite), then applies the matching recipe; full per...testinggobashVotes: 0GitHub stars: 10
Chromatic Visual Regression TestingAAuthors and runs Chromatic visual tests on Storybook, Playwright, or Cypress projects via the `chromatic` CLI; configures baselines, TurboSnap, UI Review, and CI gating; reads exit codes for change-vs-error classification. Use when the project ships visual regression coverage to Chromatic Cloud.testingbashnodeVotes: 0GitHub stars: 10
Percy Visual Regression TestingAAuthors Percy visual snapshot tests via the @percy/cli + framework SDK (Playwright, Cypress, Selenium, Storybook), runs them with `percy exec -- {test command}`, configures viewports / masking / ignored regions, and reviews diffs in the Percy build UI. Use when the project ships visual regression coverage to BrowserStack Percy.testingjavascriptgoVotes: 0GitHub stars: 10
Playwright SnapshotsAAuthors Playwright `expect(page).toHaveScreenshot()` assertions, configures masks / clips / threshold / maxDiffPixels per test, manages the per-OS / per-browser snapshot directory, and runs the update flow with `--update-snapshots`; references/ carry the responsive-breakpoint viewport matrix (one project per breakpoint, cross-breakpoint matrix report, plus Chromatic / Percy / Storybook test-runner viewport syntax). Use when the project ships self-hosted visual regression coverage in Playwrigh...testingtypescriptgoVotes: 0GitHub stars: 10
Storybook Visual Regression TestingASets up visual regression coverage for a Storybook project - either via the official @chromatic-com/storybook addon (hosted) or via @storybook/test-runner with a postVisit hook that calls Playwright's toHaveScreenshot (self-hosted). Covers test-runner install, lifecycle hooks (setup / preVisit / postVisit), and CI integration. Use when a repo already has a working `.storybook/` config and the team wants per-story visual coverage rather than page-level snapshots.testingtypescriptbashVotes: 0GitHub stars: 10
Visual Baseline ConventionsAReference catalog for visual regression coverage decisions - which Storybook stories or pages get baselines, how to choose breakpoints, when to mask vs adjust threshold, when to add or remove a baseline, and a decision matrix for picking among Percy / Chromatic / Playwright / Storybook test-runner. Use when designing visual coverage for a new project or auditing an existing baseline set.testinggodockerVotes: 0GitHub stars: 10
Visual Baseline GateAConsumes pre-classified visual-diff JSON and a reviewer-signed acceptance log to produce a single go/no-go CI verdict for visual regression. Blocks when intentional baseline changes lack a non-author reviewer sign-off or when regressions are present, and emits the binding gate artifacts - visual-gate.json + visual-gate.md - with fail-closed handling of a missing classifier run and author-cannot-self-approve enforcement, so the pipeline can exit non-zero on BLOCK. Use when the gate's input is ...testingpythonrustVotes: 0GitHub stars: 10
Browser Matrix Strategy ReferenceAPure-reference for designing and reviewing a browser / OS / device test matrix from traffic data - the T1/T2/T3 tier-membership heuristics (T1 >=5% traffic, T2 1-5% or statutory, T3 <1% with customer demand), the traffic-share sources (own analytics, StatCounter, MDN browser-compat-data), a worked matrix template with tier-change log, the matrix review checklist (staleness, T1 oversize, below-threshold T1 entries, missing real-device coverage), how to justify dropping a legacy browser (IE11, ...testinggotestingVotes: 0GitHub stars: 10
Cloud Grid E2eAAuthor and run E2E tests on a cloud browser grid - BrowserStack Automate, Sauce Labs, or LambdaTest. All three follow one pattern: username + access-key env vars, a W3C WebDriver hub URL, a vendor options dict inside the capabilities (bstack:options / sauce:options / LT:Options), a local tunnel binary for internal apps, session pass/fail reporting, and a CI matrix throttled to the plan's parallel-session limit. Worked example uses BrowserStack; per-vendor deltas live in references/. Use for c...testingpythonbashVotes: 0GitHub stars: 10
Cypress TestingAAuthors and improves Cypress E2E tests - installs Cypress, configures `cypress.config.ts`, authors `cy.*` command chains, refactors existing specs (`cy.wait(ms)` sleeps into assertions, repeated flows into `cy.session` custom commands), and debugs with the time-travel GUI; Cypress Cloud for parallel runs and recording. Use for both greenfield test authoring and improving hand-written specs already in the codebase. For automated refactor of raw Cypress Studio recordings specifically, use a ded...testingtypescriptrustVotes: 0GitHub stars: 10
Playwright TestingAAuthors and remediates Playwright E2E tests across Chromium, Firefox, WebKit - `npm init playwright@latest` scaffolding, `playwright.config.ts` browser projects, accessibility-first locators (`getByRole`/`getByLabelText`) to replace brittle CSS selectors, web-first assertions to eliminate `waitForTimeout` flakiness, Page Object pattern, trace viewer debugging, sharded parallel execution with merged HTML reporting, mobile-web emulation via the `devices` catalog (viewport / DPR / touch per-devi...testingjavascripttypescriptVotes: 0GitHub stars: 10
Selenium Grid 4 RunnerAAuthor and operate Selenium Grid 4 - self-hosted distributed WebDriver. Covers the six-component architecture (Router / Distributor / Session Map / Event Bus / New Session Queue / Node), standalone vs hub-and-node modes, the Docker-image stack (selenium/standalone-chrome, selenium/hub, selenium/node-chrome), node registration, session-queue tuning, and observability. Use for self-hosted cross-browser testing when data residency or cost-control require an on-prem grid. This is the self-hosted ...testingpythongoVotes: 0GitHub stars: 10
Selenium TestingAAuthors Selenium WebDriver tests in any of its 6+ supported languages (Java, Python, JavaScript, C#, Ruby, Kotlin, PHP) - picks the appropriate language binding, configures WebDriver per browser, uses `By.*` locators with the team's accessibility-first preference where supported, runs locally + via Selenium Grid for distributed execution, parses results to JUnit XML. Use for legacy Selenium-locked stacks; new projects pick Playwright or Cypress.testingjavascriptpythonVotes: 0GitHub stars: 10
Web E2e OverviewBTeaches web end-to-end testing from first principles: what browser-driven E2E covers and how it differs from unit and integration tests, a decision table for choosing between Playwright, Cypress, Selenium WebDriver, WebdriverIO, Puppeteer, TestCafe and the BrowserStack / Sauce Labs / LambdaTest cloud grids based on files already present in the repo, install and first-run commands for each, and the flakiness traps (fixed sleeps, CSS and XPath selectors, state shared between tests) that sink ne...testingjavascriptpythonVotes: 0GitHub stars: 10
Webdriverio TestingBAuthors WebdriverIO E2E tests - `npm init wdio@latest` scaffolding, services architecture (sauce, browserstack, appium, devtools), reporters (spec, allure, junit), built-in Mocha/Jasmine/Cucumber framework integrations. WebdriverIO sits between Selenium (W3C protocol) and Playwright (modern API) - Selenium-protocol-compatible with rich plugin ecosystem. Use when the team needs WebDriver protocol + service-based device-farm integration.testingjavascripttypescriptVotes: 0GitHub stars: 10
