Invoke any time a user is writing iOS/Swift tests or asking why tests behave a certain way — including XCTest versus Swift Testing (@Test/#expect) choices, async ViewModel tests with @Observable or @Published, snapshot testing across device sizes, mocking protocols for dependency injection, setUp/tearDown lifecycle issues, tests that fail on CI but pass locally, flaky async tests, testing VIPER/TCA/MVVM architectures, and coverage gaps on error paths. The trigger is user intent: they are…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
> **Approach: F.I.R.S.T-First, Production-Ready Tests** -- Every test produced by this skill must be Fast, Isolated, Repeatable, Self-validating, and Thorough. Architecture changes to production code and improvements to the test suite both follow phased, low-risk PRs tracked in a `refactoring/` directory. # iOS Swift Testing Enterprise-grade testing skill covering 11 areas across all iOS architectures. Opinionated: prescribes Swift Testing (`@Test`/`@Suite`/`#expect`) for all new tests on Xcode 16+, protocol-based mocks with call tracking, F.I.R.S.T compliance checks on every generated test, and architecture-specific patterns for MVVM (UIKit+Combine, SwiftUI+@Observable), VIPER, and TCA. ## Test Distribution Rule Target: 90% unit tests (mocked, milliseconds) | 8% integration (real DB/network stub) | 2% UI (XCUITest). When in doubt, write a unit test. ## F.I.R.S.T Principles | Principle | What it means | Violation signal | |-----------|--------------|-----------------| | **F**ast | Unit tests should run in milliseconds. Avoid unnecessary waits. | Real `URLSession`, `Thread.sleep`, disk I/O | …

How to install
mdr add rusel95/ios-agent-skills/ios-testing@sha256:5517029c9cae2e7fThe line at the top of this page pins the label v2.1.3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
