Example 11 with CheckedRunnable

use of io.vavr.CheckedRunnable in project resilience4j by resilience4j.

the class EventPublisherTest method shouldReturnAfterTwoAttempts.

@Test
public void shouldReturnAfterTwoAttempts() {
    // Given the HelloWorldService throws an exception
    BDDMockito.willThrow(new WebServiceException("BAM!")).willNothing().given(helloWorldService).sayHelloWorld();
    // Create a Retry with default configuration
    Retry retry = Retry.ofDefaults("id");
    TestSubscriber<RetryEvent.Type> testSubscriber = toFlowable(retry.getEventPublisher()).map(RetryEvent::getEventType).test();
    // Decorate the invocation of the HelloWorldService
    CheckedRunnable retryableRunnable = Retry.decorateCheckedRunnable(retry, helloWorldService::sayHelloWorld);
    // When
    Try<Void> result = Try.run(retryableRunnable);
    // Then the helloWorldService should be invoked 2 times
    BDDMockito.then(helloWorldService).should(Mockito.times(2)).sayHelloWorld();
