Class ExpectedToFailExtension

java.lang.Object

groovy.junit6.plugin.ExpectedToFailExtension

All Implemented Interfaces:

Extension, InvocationInterceptor, TestInstantiationAwareExtension

public class ExpectedToFailExtension
extends Object
implements InvocationInterceptor

JUnit 5 InvocationInterceptor backing the ExpectedToFail annotation. Inverts a test's pass/fail outcome with optional exception-type and message-substring filters.

Composes with ForkedJvm in either declaration order via explicit coordination through ExtensionContext.Store and a child-JVM system property — not via brittle reliance on annotation iteration order.

Since:

6.0.0

Field Details

DEFERRED_TO_PARENT_PROP

public static final String DEFERRED_TO_PARENT_PROP

System property set on the child JVM's command line by ForkedJvmExtension when the parent's @ExpectedToFail has claimed the inversion. The child's @ExpectedToFail interceptor checks this property and passes through honestly so the parent can observe the propagated outcome.
