What problem does it solve?
This Skill eliminates the friction of writing reliable, maintainable Kotlin tests by providing standardized, idiomatic patterns for TDD, mocking, coroutine testing, and coverage tracking, removing the guesswork from setting up robust test suites for Kotlin projects.
Core Features & Use Cases
- TDD Workflow Guidance: Step-by-step RED/GREEN/REFACTOR cycle examples for implementing Kotlin functions and classes following test-driven development principles.
- Kotest & MockK Patterns: Ready-to-use examples for all common Kotest spec styles, MockK dependency mocking (including coroutine mocking and argument capture), and custom matcher creation.
- Coverage & CI Integration: Kover configuration templates and GitHub Actions examples to enforce 80%+ test coverage and integrate testing into continuous integration pipelines.
Use case example: If you are building a Kotlin microservice with Ktor, use this Skill to quickly set up testApplication tests for your API routes and mock external payment and database dependencies.
Quick Start
Use the kotlin-testing skill to write a full set of passing unit tests for your new Kotlin data class following TDD principles, including MockK mocks for its repository dependencies and Kover coverage validation.
