Go testing patterns for production-grade code: subtests, test helpers, fixtures, golden files, httptest, testcontainers, property-based testing, and fuzz testing. Covers mocking strategies, test isolation, coverage analysis, and test design philosophy. Use when writing tests, improving coverage, reviewing test quality, setting up test infrastructure, or choosing a testing approach. Trigger examples: "add tests", "improve coverage", "write tests for this", "test helpers", "mock this dependency", "integration test", "fuzz test". Do NOT use for performance benchmarking methodology (use go-performance-review), security testing (use go-security-audit), or table-driven test patterns specifically (use go-test-table-driven).
Write Foundry-based tests and scripts. Trigger phrases - foundry testing, write test, fuzz test, fork test, invariant test, deploy script, gas benchmark, coverage, or when working in tests/ or scripts/ directories.
Fuzzing skill for automated input-driven bug finding in C/C++. Use when setting up libFuzzer or AFL++ fuzz targets, defining fuzz entry points around parsing or I/O boundaries, integrating fuzzing into CI, managing corpora, or combining fuzzing with sanitizers. Activates on queries about libFuzzer, AFL, afl-fuzz, fuzz targets, corpus management, coverage-guided fuzzing, or OSS-Fuzz integration.
Coverage-guided fuzzing workflow for C/C++, Rust, and Go targets. Runs audit-context-building to find suspicious code, writes a targeted harness, builds with sanitizers, runs the fuzzer, and reports crashes.
Designs and writes tests that catch real regressions — placement (unit/integration/E2E), factories and fixtures, behavior-first assertions, characterization tests for legacy code, property/fuzz tests for parsers. Use when asked to 'write tests', 'add test coverage', 'test this module', 'напиши тесты', when a bug fix needs its regression test, or when awesome-bug-fix, awesome-code-review, or awesome-security-audit calls for a failing or regression test. Do not use for judging existing tests in a review — use awesome-code-review; not for diagnosing the bug itself — use awesome-bug-fix.
Enforces test doctrine where shape follows code not the pyramid: pushes logic into Flutter-free packages tested with pure package:test and an injected Clock; asserts invariants with seeded fuzz tests against an independent oracle plus round-trip and rounding goldens; prefers bare-implements fakes over mocktail for code you own; tests the data layer against a real NativeDatabase.memory Drift engine, never a mocked DAO; drives Notifiers headlessly with ProviderContainer overrides; guards one end-to-end acceptance gate and a runtime invariant tripwire; floors coverage on unrecoverable-bug files not a global percentage; and fixes the coverage-lies-upward gap. Use when writing tests under test/ or integration_test/, choosing unit vs widget vs integration, adding a fuzz or round-trip property, wiring a fake or ProviderContainer test, gating coverage, or triaging a flaky-suite failure.
