What problem does it solve?

This Skill guides Kotlin developers in implementing reliable, maintainable, and comprehensive testing strategies to ensure code quality and robustness.

Core Features & Use Cases

  • Testing Workflow: Demonstrates TDD cycle, including writing failing tests, minimal implementation, and refactoring.
  • Test Style Guidance: Explains usage of StringSpec, FunSpec, BehaviorSpec, and DescribeSpec to cover different testing approaches.
  • Mocking and Coroutines: Shows how to mock dependencies with MockK, including coroutine functions, argument capture, and spying.
  • Property-Based Testing: Introduces Kotest property testing for generating diverse inputs and verifying invariants.
  • Integration Testing: Details methods for testing HTTP APIs with testApplication, flow testing, and test dispatcher control.
  • Test Lifecycle & Fixtures: Explains setup, cleanup, and managing test environments for reliability.
  • Coverage & CI/CD: Includes configuration and commands for Kover coverage and continuous integration setup.

Quick Start

To perform a TDD cycle for a Kotlin validation function, define the test first, run to see failure, then implement code to pass, and refactor as needed.

Frequently Asked Questions about kotlin-testing

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

FAQPage Schema
How do I test Kotlin coroutines with MockK?

To test Kotlin coroutines with MockK, you mock coroutine functions using argument capture and spying to verify asynchronous behavior. This Skill demonstrates managing test dispatchers and flow testing to ensure your coroutine logic executes reliably.

What is the best way to structure TDD cycles in Kotlin?

The best way to structure TDD cycles in Kotlin is to write a failing test first, implement the minimal code to pass, and then refactor. This Skill demonstrates this workflow using Kotlin-specific testing specs like StringSpec and BehaviorSpec.

How does property-based testing work in Kotest?

Property-based testing in Kotest works by generating diverse inputs automatically to verify that your code invariants hold true across edge cases. This Skill introduces Kotest property testing to validate logic beyond fixed unit test scenarios.

Can I use Kotest and MockK for integration testing HTTP APIs?

Yes, you can use Kotest and MockK for integration testing HTTP APIs by utilizing testApplication to run endpoints and verify responses. This Skill details methods for testing HTTP APIs, flow testing, and test dispatcher control.

How do I configure Kover coverage for Kotlin CI/CD pipelines?

You configure Kover coverage for Kotlin CI/CD pipelines by integrating coverage tools with your continuous integration setup. This Skill includes configuration commands for Kover to track code quality assurance metrics during automated builds.

What testing style should I choose in Kotest?

You should choose a Kotest testing style based on your domain: StringSpec for simple tests, FunSpec for JUnit-like structure, BehaviorSpec for BDD, and DescribeSpec for nested descriptions. This Skill explains usage across these different testing approaches.
