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.

interceptTestMethod(Invocation<Void> invocation, ReflectiveInvocationContext<Method> invocationContext, ExtensionContext extensionContext) |
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.
