Class ForkedJvmTestRunner

java.lang.Object

groovy.junit6.plugin.ForkedJvmTestRunner

public final class ForkedJvmTestRunner
extends Object

Child-JVM entry point for ForkedJvm-annotated tests.

Invoked by ForkedJvmExtension with the qualified test class name and method name as command-line arguments. Runs exactly that one test method via the JUnit Platform Launcher, then reports outcome to the parent via the file referenced by the system property groovy.junit6.forked.result: empty file on success, serialized Throwable (with text fallback) on failure.

Since:

6.0.0
