SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Kotlin projects often struggle to adopt consistent testing practices across Kotest patterns, MockK mocks, coroutine testing, property-based testing, and code coverage tooling, leading to brittle tests and slow feedback.

Core Features & Use Cases

  • Provides structured guidance for using Kotest spec styles (StringSpec, FunSpec, BehaviorSpec, DescribeSpec)
  • Demonstrates effective mocking with MockK, including coroutine mocks and argument capture
  • Covers testing asynchronous code with Kotlin coroutines, runTest, and Flow
  • Includes property-based testing patterns and test-driven development workflows
  • Helps teams achieve solid test coverage with Kover integration and practical examples
  • Use Case: add reliable tests to a Kotlin project to improve maintainability and confidence

Quick Start

Install or load this skill and begin by reviewing the examples to craft a small Kotest test suite using MockK and coroutines.

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 and Flow with runTest?

To test Kotlin coroutines and Flow, use the runTest API to control virtual time and verify asynchronous code behavior. This Skill demonstrates testing asynchronous code with runTest, including handling delays and Flow emissions in a reliable, maintainable way.

What is the best way to mock coroutines using MockK in Kotlin?

Mocking coroutines with MockK involves using coEvery and coVerify to stub and verify suspend functions. This Skill demonstrates effective mocking with MockK, including coroutine mocks and argument capture to isolate dependencies in your Kotlin tests.

How do I choose between Kotest spec styles like FunSpec, BehaviorSpec, and StringSpec?

Kotest spec styles like FunSpec, BehaviorSpec, and StringSpec differ in structure and syntax. This Skill provides structured guidance for using Kotest spec styles to match your testing preferences, whether function-based, behavior-driven, or string-based descriptions.

Can I apply property-based testing and TDD workflows in Kotlin projects?

Yes, you can apply property-based testing and test-driven development workflows in Kotlin projects. This Skill includes property-based testing patterns and practical test-driven steps to improve maintainability and confidence in your codebase.

How do I measure Kotlin test coverage with Kover?

You measure Kotlin test coverage with Kover by integrating the tool into your build process. This Skill helps teams achieve solid test coverage with Kover integration and practical examples to ensure reliable code validation.

Why are my Kotlin tests brittle and how can I make them more maintainable?

Kotlin tests often become brittle due to inconsistent testing practices across tools. This Skill helps you identify and apply Kotlin testing patterns for reliable, maintainable tests using Kotest, MockK, and proper coroutine testing techniques.
