testing-strategy
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.
Install
With your agent
Install OMGSkills skill "zakariaf/flutter-skills:skills/testing-strategy" into this agent's normal skills directory: call the OMGSkills MCP get_install_plan tool for your agent and run the script it returns (it installs only the pinned commit and verifies SKILL.md), and stop if MCP or the pin is unavailable. Do not overwrite or change existing skills without asking me.
Manual command
git clone https://github.com/zakariaf/Flutter-Skills /tmp/Flutter-Skills && ln -s /tmp/Flutter-Skills/skills/testing-strategy ~/.claude/skills/testing-strategyFrom README
Testing Strategy Tests are the only correctness instrument you control at build time: shape the suite to the code, not to a decades-old ratio, and make each test assert behaviour a build either passes or fails. Applies to every test under test/ and integrationtest/. Read the reference for the task at hand: references/test-layers.md — per-layer harness, imports, teardown, edge tables (pure core, in-memory Drift, headless Notifier, integration). references/property-and-fakes.md — fakes-over-mocks, enum-driven fake state, seeded fuzz, independent oracles, absence-of-a-failure-class tests. references/coverage-and-budget.md — file-level floors, the coverage-lies-upward fix, the suite-time budget, and the manual-pass handoff. Run scripts/checktesthygiene.sh and scripts/runtests.sh before a PR. Golden, RTL, and a11y widget mechanics live in widget-golden-and-a11y-testing; this skill governs everything below the pixel. Non-negotiable rules Shape the suite to the code, not the pyramid.
