Overriding Kotest Version

All modules support overriding the Kotest version via environment variables. This is useful for CI workflows that need to test against a specific or newly-built Kotest version.

Environment Variables

Variable	Description
KOTEST_VERSION	Overrides the Kotest library dependencies version
KOTEST_GRADLE_PLUGIN_VERSION	Overrides the io.kotest Gradle plugin version

Examples

# Run tests with a specific Kotest library version
cd kotest-jvm
KOTEST_VERSION=6.0.3 ./gradlew test

# Run tests with a specific Gradle plugin version
KOTEST_GRADLE_PLUGIN_VERSION=6.0.3 ./gradlew test

# Override both library and plugin versions (useful when they differ)
KOTEST_VERSION=6.1.0 KOTEST_GRADLE_PLUGIN_VERSION=6.0.3 ./gradlew test

# Or for any other module
cd kotest-multiplatform
KOTEST_VERSION=6.1.0 ./gradlew test

When no override is provided, each module uses the version from its gradle/libs.versions.toml.
