### Question:
Part10CryptoPlatform extends LoggerConfigurationTrait { public static Flux<String> handleOutgoingStreamBackpressure(Flux<String> outgoingStream) { return outgoingStream; }  static void main(String[] args); static Flux<Long> handleRequestedAveragePriceIntervalValue(Flux<String> requestedInterval); static Flux<String> handleOutgoingStreamBackpressure(Flux<String> outgoingStream);  }### Answer:
@Test public void verifyOutgoingStreamBackpressure() { DirectProcessor<String> processor = DirectProcessor.create(); StepVerifier .create( Part10CryptoPlatform.handleOutgoingStreamBackpressure(processor), 0 ) .expectSubscription() .then(() -> processor.onNext("A")) .then(() -> processor.onNext("B")) .then(() -> processor.onNext("C")) .then(() -> processor.onNext("D")) .then(() -> processor.onNext("E")) .then(() -> processor.onNext("F")) .expectNoEvent(Duration.ofMillis(300)) .thenRequest(6) .expectNext("A", "B", "C", "D", "E", "F") .thenCancel() .verify(); }
