Examples with StepVerifier reactor.test.StepVerifier used on opensource projects

Example 1 with StepVerifier

use of reactor.test.StepVerifier in project reactor-core by reactor.

the class SchedulersTest method handleErrorWithJvmFatalForwardsToUncaughtHandlerSyncInnerCallable.

@Test
public void handleErrorWithJvmFatalForwardsToUncaughtHandlerSyncInnerCallable() {
    AtomicBoolean handlerCaught = new AtomicBoolean();
    Scheduler scheduler = Schedulers.fromExecutorService(Executors.newSingleThreadExecutor(r -> {
        Thread thread = new Thread(r);
        thread.setUncaughtExceptionHandler((t, ex) -> {
            handlerCaught.set(true);
            System.err.println("from uncaught handler: " + ex.toString());
        });
        return thread;
    }));
    final StepVerifier stepVerifier = StepVerifier.create(Flux.just("hi").flatMap(item -> Mono.<String>fromCallable(() -> {
        throw new StackOverflowError("boom");
    }).hide().subscribeOn(scheduler))).expectNoFusionSupport().expectErrorMessage(// ignored
    "boom");
    // the exception is still fatal, so the StepVerifier should time out.
    assertThatExceptionOfType(AssertionError.class).isThrownBy(() -> stepVerifier.verify(Duration.ofMillis(100))).withMessageStartingWith("VerifySubscriber timed out on ");
    // nonetheless, the uncaught exception handler should have been invoked
    assertThat(handlerCaught).as("uncaughtExceptionHandler used").isTrue();
}
