Enforces rigorous verification evidence before any claims of task completion, preventing false positives, untested deployments, and premature celebration with a structured gate function.
Svelte component testing with @testing-library/svelte, vitest, component rendering, event simulation, store testing, and SvelteKit testing.

Validate error boundary implementations in React and other frameworks ensuring graceful degradation, proper fallback UI rendering, and error recovery flows
Generate and evaluate mutation tests to assess test suite effectiveness by introducing controlled code mutations and verifying test detection rates
by thetestingacademy
Review pull requests for test coverage like a senior SDET, map the diff to required test classes, spot untested branches and missing regression tests, judge test quality not just presence, and write actionable review comments.
Comprehensive testing patterns for Model Context Protocol servers including tool validation, transport testing, schema verification, and end-to-end MCP integration testing with stdio and SSE transports.
Testing patterns for Drizzle ORM covering migration testing, query builder testing, transaction testing, and database integration testing with PostgreSQL, SQLite, and MySQL.
Author effective Cursor rules in .cursor/rules/*.mdc - YAML frontmatter (description, globs, alwaysApply), the four rule types, scoped QA rules, subagents, and structure that actually steers the model.
Go testing with testing package, table-driven tests, subtests, benchmarks, test fixtures, httptest, and testify assertions.
HTTP request mocking with Nock for Node.js testing including request intercepting, response recording, and external API simulation.
Advanced mutation testing using Stryker, PIT, and mutmut to measure test suite quality by introducing controlled mutations and tracking kill rates.
Building hermetic tests that are fully isolated from external dependencies using fakes, containers, and deterministic time/random sources.
Optimizing test suite execution speed with parallelization, test splitting, caching, selective test execution, and test impact analysis.
.NET testing with xUnit, NUnit, MSTest, FluentAssertions, Moq, integration testing with WebApplicationFactory, and Entity Framework testing.
Effective patterns for using GitHub Copilot to generate, refactor, and maintain test code including prompt engineering for test generation, Copilot Chat for debugging, inline suggestions for assertions, and workspace context optimization.
Generate high-signal unit tests for existing code, behavior-first case selection, boundary and error paths, mocking discipline, mutation-tested quality, and framework-idiomatic output for Vitest, Jest, and pytest.
Testing WebAssembly modules including compilation verification, memory management, interop testing, and performance benchmarking of WASM components.
Effective test automation patterns with Cursor AI IDE including Composer for test suite generation, Cmd+K for inline test edits, Chat for test debugging, codebase-aware test generation, and rules configuration for testing conventions.
Generate optimized test combinations using pairwise (all-pairs) testing algorithms to achieve maximum coverage with minimum test cases across multiple input parameters
