What problem does it solve?
This Skill helps Kotlin developers write dependable tests without fighting inconsistent styles, fragile mocks, or unclear coverage goals. It turns test creation into a guided workflow that supports TDD and maintainable quality checks.
Core Features & Use Cases
- Kotest Spec Selection: Choose the right spec style for unit, integration, or behavior-focused tests.
- MockK Isolation: Mock collaborators cleanly, including suspending dependencies and argument capture.
- Coroutine and Flow Testing: Verify async behavior with controlled dispatchers, delays, and emissions.
- Property-Based Testing: Validate pure functions and data roundtrips across many generated inputs.
- Coverage and CI Guidance: Track and enforce coverage targets with Kover in local and automated builds.
- Use Case: A Kotlin team adding a new service can start with a failing test, mock external dependencies, validate coroutine logic, and confirm coverage before merging.
Quick Start
Use the kotlin-testing skill to design Kotest tests for your Kotlin codebase, mock dependencies with MockK, and verify coroutine behavior and coverage in a TDD workflow.
