Expert blueprint for testing patterns using GUT (Godot Unit Test), integration tests, mock/stub patterns, async testing, and validation techniques. Covers assert patterns, signal testing, and CI/CD integration. Use when implementing tests OR validating game logic. Keywords GUT, unit test, integration test, assert, mock, stub, GutTest, watch_signals, TDD.
Testing Inertia Rails responses with RSpec and Minitest: component assertions, prop matching, flash verification, deferred props, and partial reload helpers. Use when writing controller specs, request specs, or integration tests for Inertia pages. ALWAYS use matchers (render_component, have_props, have_flash), NOT direct access (inertia.component, inertia.props). CRITICAL: after POST/PATCH/DELETE with redirect, MUST call follow_redirect! before asserting flash or props — without it you're asserting against the 302, not the Inertia page. Setup: require 'inertia_rails/rspec'.
Write and run tests for JS/TS projects. Handles unit tests with Vitest and React Testing Library directly. Delegates E2E and browser testing to /webapp-testing. Use when writing tests, adding coverage, debugging test failures, or running test suites.
Tool-based API testing with Postman and Bruno - collections, environments, test assertions, CI integration. Use when: postman, bruno, API testing, test API endpoint, API collection, HTTP request testing, endpoint validation.
Guide users step-by-step through manually testing whatever is currently being worked on. Use when asked to "test this", "verify it works", "let's test", "manual testing", "QA this", "check if it works", or after implementing a feature that needs verification before proceeding.
Write and run Go tests using the built-in testing package with table-driven tests, subtests, and mocking via interfaces. Use when writing Go tests or setting up test infrastructure.
Property-based testing with fast-check (TypeScript/JavaScript) and Hypothesis (Python). Generate test cases automatically, find edge cases, and test mathematical properties. Use when user mentions property-based testing, fast-check, Hypothesis, generating test data, QuickCheck-style testing, or finding edge cases automatically.
Write and evaluate effective Python tests using pytest. Use when writing tests, reviewing test code, debugging test failures, or improving test coverage. Covers test design, fixtures, parameterization, mocking, and async testing.
Visual testing, UI verification, and design comparison using screenshots and Figma integration. Use when the user wants to verify UI appearance, compare with Figma designs, test responsive layouts, check for visual regressions, or validate design implementation.
Unit testing, integration testing, and test-driven development principles. Use when writing tests, reviewing test code, improving test coverage, or setting up testing strategy. Triggers on "write tests", "review tests", "testing best practices", or "TDD".
WCAG 2.2 compliance testing, screen reader validation, and inclusive design verification. Use when ensuring legal compliance (ADA, Section 508), testing for disabilities, or building accessible applications for 1 billion disabled users globally.
Guide for testing workflows and code generation commands in Biome. Use when running tests, managing snapshots, creating changesets, or generating code. Examples:<example>User needs to run snapshot tests for a lint rule</example><example>User wants to create a changeset for a PR</example><example>User needs to regenerate analyzer code after changes</example>
