What problem does it solve?
This Skill removes the friction of writing inconsistent, hard-to-maintain Kotlin tests by providing standardized, idiomatic patterns for TDD, mocking, coroutine testing, and coverage tracking, eliminating guesswork when setting up robust test suites for Kotlin projects.
Core Features & Use Cases
- TDD Workflow Guidance: Step-by-step RED/GREEN/REFACTOR cycle tailored for Kotlin, with runnable examples for common use cases like validators and service classes.
- Comprehensive Tooling Patterns: Ready-to-use examples for Kotest spec styles, MockK mocking (including coroutine mocking and argument capture), coroutine/flow testing with runTest, and property-based testing.
- Coverage & CI Integration: Kover configuration templates and GitHub Actions workflows to enforce 80%+ coverage thresholds and automate test runs.
Use case example: If you're building a Kotlin microservice with Ktor, use this Skill to quickly set up testApplication tests for your API routes and mock external payment dependencies with MockK.
Quick Start
Use the kotlin-testing skill to write a full set of Kotest tests for your existing Kotlin data class, including MockK mocks for its dependencies and a Kover coverage check to ensure 80%+ test coverage.
