The file

We split this kotlin-testing.md into the rules it gives an agent

3 rules. About 0 are common, 2 are distinctive, and 1 is very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈2

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 1

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Distinctive:

    Use Kotest with spec styles (StringSpec, FunSpec, BehaviorSpec) and MockK for mocking.

    line 12
  2. Very specific:

    Use runTest from kotlinx-coroutines-test:

    line 16
  3. Distinctive:

    Use Kover for coverage reporting:

    line 29

≈ “Common” is an estimate: at least 1 in 5 of the 6,668 Cursor rule files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Kotlin Testing

This file extends the common testing rule with Kotlin-specific content.

Framework

Use Kotest with spec styles (StringSpec, FunSpec, BehaviorSpec) and MockK for mocking.

Coroutine Testing

Use runTest from kotlinx-coroutines-test:

test("async operation completes") {
    runTest {
        val result = service.fetchData()
        result.shouldNotBeEmpty()
    }
}

Coverage

Use Kover for coverage reporting:

./gradlew koverHtmlReport
./gradlew koverVerify

Reference

See skill: kotlin-testing for detailed Kotest patterns, MockK usage, and property-based testing.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
