Code Review Summary

Status: Approved

Overview

This PR consolidates duplicate test task configuration from 9 individual module build.gradle.kts files into a single centralized block in the root build.gradle.kts under subprojects { }. This is a good maintainability improvement that follows the DRY principle.

Changes Reviewed

File	Changes
build.gradle.kts	Added centralized test configuration in subprojects block
gradle.properties	Added -XX:+HeapDumpOnOutOfMemoryError JVM flag
9 module build files	Removed duplicate test configuration blocks

Key Details

1. Test Configuration Centralization: All common test settings (useJUnitPlatform, forkEvery, maxHeapSize, maxParallelForks, jvmArgs) are now defined once in the root build.gradle.kts.

2. forkEvery Optimization: Increased from 100 to 500 to reduce JVM restarts during test execution, which should improve test performance.

3. maxHeapSize: The 2g heap size setting is preserved in the centralized configuration.

4. Heap Dump Flag: Added -XX:+HeapDumpOnOutOfMemoryError to gradle.properties for better debugging of OOM issues.

5. Module-Specific Config: The ui module correctly retains its test task block containing only the module-specific android.sourceSets configuration.

Verification

• All common test settings are properly centralized
• Module-specific configurations are preserved where needed
• The @Suppress("UselessCallOnNotNull") annotation on jvmArgs.orEmpty() is appropriate

No issues identified.

I have moved the test configs to this singular spot for convenience but there are also some small changes too.

• I have increased the forkEvery count to avoid spinning up so many JVM instances
• I have completely removed the maxHeapSize property to allow the jvm args from the gradle.properties to handle it (-Xmx4g).

Nice! @LRNcardozoWDF this may help the extra resource consumption you were noticing.

[david-livefront]

Required for some warnings coming from the configuration on release builds.

Thoughts on if we should just remove the configuration cache completely?

[SaintPatrck]

Removing the configuration cache completely will probably increase build times, so I'm hesitant to go that route. What are the warnings you are seeing?
