Examples with Exceptions reactor.core.Exceptions used on opensource projects

Example 1 with Exceptions

use of reactor.core.Exceptions in project reactor-core by reactor.

the class MonoDoOnEachTest method consumerBubbleError.

@Test
public void consumerBubbleError() {
    LongAdder state = new LongAdder();
    Throwable err = new Exception("test");
    assertThatThrownBy(() -> StepVerifier.create(Mono.just(1).doOnEach(s -> {
        if (s.isOnNext()) {
            state.increment();
            throw Exceptions.bubble(err);
        }
    })).expectErrorMessage("test").verify()).isInstanceOf(RuntimeException.class).matches(Exceptions::isBubbling, "bubbling").hasCause(// equivalent to unwrap for this case
    err);
    assertThat(state.intValue()).isEqualTo(1);
}

Example 2 with Exceptions

use of reactor.core.Exceptions in project reactor-core by reactor.

the class FluxOnBackpressureBufferTest method onBackpressureBufferMaxCallbackOverflow.

@Test
public void onBackpressureBufferMaxCallbackOverflow() {
    AtomicInteger last = new AtomicInteger();
    StepVerifier.create(Flux.range(1, 100).hide().onBackpressureBuffer(8, last::set, BufferOverflowStrategy.ERROR), 0).thenRequest(7).expectNext(1, 2, 3, 4, 5, 6, 7).then(() -> assertThat(last.get()).isEqualTo(16)).thenRequest(9).expectNextCount(8).verifyErrorMatches(Exceptions::isOverflow);
}

Example 3 with Exceptions

use of reactor.core.Exceptions in project reactor-core by reactor.

the class FluxOnBackpressureBufferTest method onBackpressureBufferMaxCallback.

@Test
public void onBackpressureBufferMaxCallback() {
    AtomicInteger last = new AtomicInteger();
    StepVerifier.create(Flux.range(1, 100).hide().onBackpressureBuffer(8, last::set), 0).thenRequest(7).expectNext(1, 2, 3, 4, 5, 6, 7).then(() -> assertThat(last.get()).isEqualTo(16)).thenRequest(9).expectNextCount(8).verifyErrorMatches(Exceptions::isOverflow);
