Kotlin testing patterns with Kotest, MockK, coroutine testing, property-based testing, and Kover coverage. Follows TDD methodology with idiomatic Kotlin practices.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Kotlin Testing Patterns Comprehensive Kotlin testing patterns for writing reliable, maintainable tests following TDD methodology with Kotest and MockK. ## When to Use - Writing new Kotlin functions or classes - Adding test coverage to existing Kotlin code - Implementing property-based tests - Following TDD workflow in Kotlin projects - Configuring Kover for code coverage ## How It Works 1. **Identify target code** — Find the function, class, or module to test 2. **Write a Kotest spec** — Choose a spec style (StringSpec, FunSpec, BehaviorSpec) matching the test scope 3. **Mock dependencies** — Use MockK to isolate the unit under test 4. **Run tests (RED)** — Verify the test fails with the expected error 5. **Implement code (GREEN)** — Write minimal code to pass the test 6. **Refactor** — Improve the implementation while keeping tests green 7. **Check coverage** — Run `./gradlew koverHtmlReport` and verify 80%+ coverage ## Examples The following sections contain detailed, runnable examples for each testing pattern: ### Quick Reference - **Kotest specs** — StringSpec, FunSpec, BehaviorSpec, DescribeSpec examples in [Kotest Spec Styles](#kotest-spec-styles) …

How to install
mdr add affaan-m/ecc/kotlin-testing@sha256:46f9f7da6a639103The line at the top of this page pins the label git:20260607.4ad5756, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
