### Question:
Part5ResilienceResponsive_Optional { @Complexity(HARD) public static Publisher<Integer> provideSupportOfContinuationWithoutErrorStrategy(Flux<Integer> values, Function<Integer, Integer> mapping) { return values.map(mapping); }  @Complexity(HARD) static Publisher<Integer> provideSupportOfContinuation(Flux<Integer> values); @Complexity(HARD) static Publisher<Integer> provideSupportOfContinuationWithoutErrorStrategy(Flux<Integer> values, Function<Integer, Integer> mapping);  }### Answer:
@Test public void provideSupportOfContinuationWithoutErrorStrategyTest() { Function<Integer, Integer> mapping = i -> 10 / i; Flux<Integer> range = Flux.range(0, 6); StepVerifier.create(provideSupportOfContinuationWithoutErrorStrategy(range, mapping)) .expectSubscription() .expectNextCount(5) .expectComplete() .verifyThenAssertThat() .hasNotDroppedErrors(); }
