What is run-module-tests?

A guide for choosing and running the correct Gradle test task for a project module based on its source sets and plugin type.

Finding test source sets and running shared, Android host, desktop, or standard JVM tests for a selected module.

It avoids running the wrong tests or missing platform-specific tests in a Kotlin Multiplatform project.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00026	$0.00946
Opus 5.5	$0.00010	$0.00378
Sonnet 5.5	$0.00005	$0.00189
Haiku 4.5	$0.00003	$0.00095

Security

Grade A, and why

run-module-tests scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Run the correct test task(s) for a Gradle module in this KMP project.

Arguments

$ARGUMENTS should be the Gradle module path (e.g., aktual-api, aktual-account:vm, aktual-app:desktop)
- If omitted, infer it from the most recently discussed or edited module in conversation context

Step-by-Step Process

1. Determine what test source sets exist

Check which test source set directories exist for the module under src/:

src/commonTest/     -> shared tests (run by desktopTest, and by testAndroidHostTest if the module has an android target)
src/androidHostTest/ -> Android-specific tests (runs on host JVM, Robolectric where a class opts in)
src/desktopTest/    -> JVM/Desktop-specific tests
src/test/           -> Standard JVM test (JVM-only modules)

Use Glob to check: <module-path>/src/*test*/ and <module-path>/src/*Test*/

The module path on disk uses / separators (e.g., aktual-core/api/src/commonTest), but the Gradle path uses : (e.g., :aktual-api).

2. Determine the module type

Check the module's build.gradle.kts for which convention plugin it uses:

Plugin	Module Type	Available Test Tasks
`aktual.module.kotlin` / `aktual.module.di`	KMP + Android	`allTests`, `testAndroidHostTest`, `desktopTest`
`aktual.module.compose`	KMP + Android + Compose	`allTests`, `testAndroidHostTest`, `desktopTest`
`aktual.module.viewmodel`	KMP + Android + Compose + VM	`allTests`, `testAndroidHostTest`, `desktopTest`
`aktual.module.jvm`	Plain JVM, not KMP	`test`
`aktual.module.android`	Plain Android library, not KMP	`testDebugUnitTest`

3. Choose the right task

For KMP modules:

Source Sets Present	Recommended Task	Why
Only `commonTest`	`testAndroidHostTest`	commonTest is compiled into both androidHostTest and desktopTest; pick one to avoid running twice. androidHostTest is preferred as it includes Robolectric support.
Only `androidHostTest` (with or without `commonTest`)	`testAndroidHostTest`	Runs commonTest + androidHostTest together
Only `desktopTest` (with or without `commonTest`)	`desktopTest`	Runs commonTest + desktopTest together
Both `androidHostTest` and `desktopTest`	`allTests`	Need both targets to cover all tests
`commonTest` + `androidHostTest` + `desktopTest`	`allTests`	Need both targets

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
