Kotest — flexible, idiomatic Kotlin testing framework. Multiple specification styles (StringSpec, FunSpec, BehaviorSpec, DescribeSpec, FeatureSpec, FreeSpec), rich matcher library, property-based testing, data-driven tests, coroutine support, KMP-friendly. Drop-in alternative or complement to JUnit. USE WHEN: user mentions "Kotest", "io.kotest", "shouldBe", "StringSpec", "BehaviorSpec", "DescribeSpec", "kotest property testing", "Arb.list", "forAll", "kotest matchers", "kotlin tests" DO NOT USE FOR: JUnit-specific patterns - use junit skill (or framework-specific test skills) DO NOT USE FOR: Flow testing - use `testing/turbine` DO NOT USE FOR: Compose snapshot tests - use `testing/compose-snapshot` DO NOT USE FOR: Mobile E2E - use `testing/maestro`

Generic webapp QA fallback — use only when no project-specific QA skill applies (project-local QA wins; native builds → mobile-emulator-test). Use when "QA the app", "test CRUD", or "smoke test". Monkey / guest vs logged-in → test-exploratory. Dead buttons → plan-stub-checker. Pixel diffs → test-visual-regression.

Applies practical test-first and regression testing to behavior changes, bug fixes, state transitions, and public contracts.

Test C# MCP servers at unit and integration levels using xUnit, Moq, and the MCP client SDK.

Guides test-driven development with a red-green-refactor loop, emphasizing behavior-focused tests and vertical slicing over horizontal test writing.

Generates Playwright-based browser end-to-end tests for Adobe App Builder SPAs and AEM extensions, including configs, test files, and CI workflows.

Close the PDCA loop on this session's diff. Headed playwright-cli, fix as you go. Use when "test my changes", "PDCA this". Pixel diffs → test-visual-regression. Story CRUD → test-qa. Monkey / guest vs logged-in → test-exploratory.

AL App/Test project layout diagnosis for Business Central. Use when the main app compiles test sources, AL0297 appears on test object IDs, Library Assert or Library - Sales is missing, test/app.json is not recognized, or a multi-root workspace with app and test projects needs diagnosis.

Guide for testing code changes in AEM Edge Delivery projects including blocks, scripts, and styles. Use this skill after making code changes and before opening a pull request to validate functionality. Covers unit testing, browser testing with Playwright, and linting.

Generate wrapper interfaces, default implementations, and DI registration code to make hard-to-test static dependencies in C# testable, using built-in abstractions like TimeProvider or custom wrappers.

Write tests before implementation code for new features, bug fixes, and refactoring, following the red-green-refactor cycle.

Write test-driven Laravel applications using PHPUnit, Pest, model factories, HTTP tests, Sanctum authentication testing, mocking, and coverage.

Design rigorous A/B tests with clear hypotheses, controlled variants, appropriate metrics, and sample size calculations.

Guides test-first development with vertical slices, writing one behavior test at a time and refactoring only when green.

Acceptance-test newly added features using browser automation, happy-path flows, screenshots, UX notes, and a written report.

Designs A/B tests with sample size calculation, statistical significance testing, and result interpretation

Test-Driven Development (TDD)

Write Android unit, Compose UI, and Hilt-integrated tests. Use when designing test behavior with MockK or coroutine test utilities; defer database/WorkManager-specific recipes to the owning feature skill.

Create comprehensive test plans with coverage and strategy. TRIGGERS - Use when user needs help with test-plan related tasks.

WelineFramework local testing adapter. Use when working in this repo on how to write module tests, choose validation layers, or run PHPUnit, Pest, Vitest, Playwright, HTTP smoke, Browser smoke, or WLS-backed test flows. Read dev/ai/skills/testing/SKILL.md before acting.

BDD-driven test implementation: red-green loop mechanics, seams, mocking, and test quality under BDD Automation. Use when the user wants to write or improve tests during BDD implementation, needs guidance on test structure, or asks about test seams, mocking, or anti-patterns.

Uses mutation testing to systematically identify gaps in test vector coverage for cryptographic algorithms, then generates new test vectors that close those gaps. Measures effectiveness by comparing mutation kill rates before and after.

Run pytest tests with coverage, discover lines missing coverage, and increase coverage to 100%.

Use only when writing/updating/fixing C++ tests, configuring GoogleTest/CTest, diagnosing failing or flaky tests, or adding coverage/sanitizers.

Upgrades PowerShell Pester test suites across major versions (v3→v4, v4→v5, v5→v6) with structured workflows, reference guides, and safety rules.

Runs a disciplined diagnosis loop for hard bugs and performance regressions, from reproduction through hypothesis testing, instrumentation, fixing, and regression testing.

Write and run unit tests with Vitest, covering mocking, snapshots, coverage, and test filtering.

Generates unit tests for multiple languages and frameworks, including coverage reports and boundary/exception cases.
