the class RunnableRetryTest method shouldReturnAfterOneAttemptAndIgnoreException.

@Test
public void shouldReturnAfterOneAttemptAndIgnoreException() {
    // Given the HelloWorldService throws an exception
    BDDMockito.willThrow(new WebServiceException("BAM!")).given(helloWorldService).sayHelloWorld();
    // Create a Retry with default configuration
    RetryConfig config = RetryConfig.custom().retryOnException(throwable -> Match(throwable).of(Case($(Predicates.instanceOf(WebServiceException.class)), false), Case($(), true))).build();
    Retry retry = Retry.of("id", config);
    // 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 only once, because the exception should be rethrown immediately.
    BDDMockito.then(helloWorldService).should(Mockito.times(1)).sayHelloWorld();
    // and the result should be a failure
    Assertions.assertThat(result.isFailure()).isTrue();
    // and the returned exception should be of type RuntimeException
