Analyzes changed files and improves unit test coverage using project-specific testing conventions from .trellis/spec/ unit-test specs. Determines test scope (unit vs integration vs regression), adds or updates tests following existing patterns, and runs validation. Use when code changes need test coverage, after implementing a feature, after fixing a bug, or when test gaps are identified.
Use when choosing a testing strategy, right-sizing test coverage, or understanding test categories. Covers the Test Trophy model, test type tradeoffs, and guidance on balancing static analysis, unit, integration, and end-to-end tests. USE FOR: testing strategy, Test Trophy, test type selection, right-sizing test coverage, balancing test categories, choosing testing tools, test automation architecture DO NOT USE FOR: specific test category implementation (use static-analysis, unit-testing, integration-testing, e2e-testing, etc.), BDD specification authoring (use specs/documentation/gherkin)
Guidance for configuring dependency injection in .NET MAUI apps — service registration in MauiProgram.cs, lifetime selection (Singleton / Transient / Scoped), constructor injection, Shell navigation auto-resolution, platform-specific registrations, and testability patterns. USE FOR: "dependency injection", "DI setup", "AddSingleton", "AddTransient", "AddScoped", "service registration", "constructor injection", "IServiceProvider", "MauiProgram DI", "register services", "BindingContext injection". DO NOT USE FOR: data binding (use maui-data-binding), Shell route configuration (use maui-shell-navigation), unit-test mocking frameworks (use standard xUnit and NSubstitute patterns).
Implement a unit-test runner script (Bash on macOS/Linux, PowerShell on Windows) for an arbitrary programming language, following the same conceptual pattern as the bundled Java reference script in assets/. Use when the user wants to add a testing script for a new language (Python, Node.js, Go, Rust, etc.) to a ***plain project, or wants to regenerate / adapt the existing Java runner.
Bring up I2C sensors on a XIAO ESP32S3 and stream their values to serial: BH1750 ambient light, BME280 temperature/pressure/humidity, and BNO055 9-DOF fused orientation, individually as unit tests or all three together on one bus. Use this skill WHENEVER the task involves I2C sensors on an ESP32S3 — wiring one up, "센서 값 읽어줘", a sensor that answers the scan but reads zeros, unit-testing a module before trusting it, deciding whether a 0x76 part is a BME280 or a BMP280, or a BNO055 whose orientation stays at 0. It carries hardware-verified sketches and the address/clock traps that make a healthy-looking sensor return nothing.
Write comprehensive backend tests including unit tests, integration tests, and API tests. Use when testing REST APIs, database operations, authentication flows, or business logic. Handles Jest, Pytest, Mocha, testing strategies, mocking, and test coverage.
Design comprehensive testing strategies for software quality assurance. Use when planning test coverage, implementing test pyramids, or setting up testing infrastructure. Handles unit testing, integration testing, E2E testing, TDD, and testing best practices.
Implements unit, widget, and integration tests for a Flutter app. Use when ensuring code quality and preventing regressions through automated testing.
Add Flutter unit tests, widget tests, or integration tests
Testing strategy and workflow. Tests run in parallel with isolated data per suite. Prioritize Playwright for UI, integration tests for APIs, unit tests for logic.
Configure unit testing with Bun's built-in test runner. Fast, Jest-compatible syntax, co-located test files, and mocking support.
Use this skill when writing new features, fixing bugs, or refactoring code. Enforces test-driven development with 80%+ coverage including unit, integration, and E2E tests.
