SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill eliminates the common pain points of writing inconsistent, hard-to-maintain Kotlin test suites, struggling to follow TDD methodology, and failing to meet code coverage targets for Kotlin projects.

Core Features & Use Cases

  • TDD Workflow Guidance: Walks you through the full RED/GREEN/REFACTOR cycle for Kotlin code, ensuring tests drive implementation.
  • Comprehensive Testing Tooling: Covers Kotest spec styles, MockK mocking for unit and coroutine tests, property-based testing, and Kover coverage configuration.
  • Use Case: Use this Skill to write unit tests for a Kotlin microservice, mock external API dependencies with MockK, and enforce 80%+ code coverage via Kover in your CI pipeline.

Quick Start

Use the kotlin-testing skill to write a complete set of unit tests for your Kotlin user service class following TDD principles, including MockK mocks for repository dependencies and Kover coverage configuration.

Frequently Asked Questions about kotlin-testing

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I write Kotlin unit tests that properly mock coroutine dependencies?▼

Proper coroutine testing in Kotlin utilizes MockK to mock suspending functions and manage asynchronous flows. This ensures maintainable unit tests with consistent dependency mocking for asynchronous code paths.

What is the best way to enforce code coverage thresholds in a Kotlin project?▼

Enforcing code coverage thresholds in Kotlin is achieved by configuring Kover in your CI pipeline. This eliminates low-coverage test suites by failing builds that do not satisfy your enforced coverage targets.

How do I follow a TDD workflow when building a Kotlin microservice?▼

TDD workflows for Kotlin microservices follow the full RED/GREEN/REFACTOR cycle to ensure tests drive implementation. This methodology eliminates inconsistent test suites by standardizing idiomatic testing patterns.

Does Kotest support property-based testing for Kotlin projects?▼

Kotest supports property-based testing to provide comprehensive testing tooling for Kotlin projects. This allows developers to validate code behavior across a wide range of generated inputs using standardized spec styles.

Can I use MockK for mocking external API dependencies in Kotlin unit tests?▼

MockK can be used to mock external API dependencies in Kotlin unit tests. It provides standardized idiomatic mocking patterns that ensure proper dependency isolation and maintainable test suites.
