SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Kotlin developers often face brittle tests and maintenance overhead when tests lag behind Kotlin features; this skill provides structured testing patterns using Kotest, MockK, coroutine testing, property-based testing, and Kover coverage to improve test reliability and maintainability.

Core Features & Use Cases

  • Kotest spec styles: StringSpec, FunSpec, BehaviorSpec, DescribeSpec for flexible test organization.
  • MockK-based mocking for suspend functions and coroutine testing to isolate units.
  • TDD workflow with RED/GREEN/REFACTOR examples to guide iterations.
  • Coroutine testing techniques with runTest, delays, and advanced flows.
  • Property-based testing and data-driven testing to validate pure functions and edge cases.
  • Kover coverage configuration guidance to enforce quality gates.

Quick Start

Run the Kotlin testing patterns sample in your project to observe Kotest, MockK, and coroutine testing in action.

Frequently Asked Questions about kotlin-testing

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

FAQPage Schema
How do I test suspend functions and coroutines in Kotlin?▼

Test Kotlin coroutines using the runTest API to control delays and virtual time. This skill provides patterns for isolating suspend functions and testing advanced flows with MockK to ensure reliable asynchronous behavior.

What's the best way to organize Kotlin tests using Kotest?▼

Kotest offers flexible spec styles like StringSpec, FunSpec, BehaviorSpec, and DescribeSpec for organizing Kotlin tests. This skill demonstrates these styles to structure readable tests and enable effective TDD workflows.

How do I mock Kotlin dependencies and validate edge cases?▼

Mock Kotlin dependencies using MockK, and validate edge cases using property-based testing. This skill applies data-driven testing patterns to verify pure functions and isolate units effectively.

How do I enforce test coverage gates in a Kotlin project?▼

Enforce Kotlin test coverage by configuring Kover. This skill provides guidance on setting up Kover to establish quality gates and ensure robust coverage across production codebases.

Can I use this Kotlin testing skill for TDD workflows?▼

Yes, this skill supports TDD workflows with RED/GREEN/REFACTOR examples. It guides iterations for writing idiomatic Kotlin tests at both unit and integration levels.
