我正在尝试Mono.delay使用StepVerifier. 我的代码如下：

Mono[Long] mono = Mono.delay(Duration.ofDays(5));

StepVerifier.withVirtualTime(() -> mono)
    .thenAwait(Duration.ofDays(5))
    .expectNextCount(1)
    .expectComplete()
    .verify();

我得到以下堆栈跟踪

expectation "expectNextCount" failed (expected: count = 1; actual: counted = 0; signal: onError(reactor.core.Exceptions$BubblingException:
java.util.concurrent.RejectedExecutionException: Scheduler unavailable))
java.lang.AssertionError: expectation "expectNextCount" failed (expected: count = 1; actual: counted = 0; signal: onError(reactor.core.Exceptions$BubblingException: java.util.concurrent.RejectedExecutionException: Scheduler unavailable))

跟踪源代码后，似乎执行器在方法上被关闭Schedulers.setFactory

我想知道我是否在这里遗漏了什么。

好的，我想我已经找到问题的根源了。

StepVerifier需要Supplier，在我的情况下，我提供了已创建Mono[Long]的现有内容。Mono我应该改为执行以下操作

StepVerifier.withVirtualTime(() -> Mono.delay(Duration.ofDays(5)))
    .thenAwait(Duration.ofDays(5))
    .expectNextCount(1)
    .expectComplete()
    .verify();

这样Mono提供的将不会首先创建，并且执行器不会被关闭。
