单元测试无限重复 Flux

Question

给定一个永远重复的 Flux，我们如何对其进行单元测试？假设我想断言第一组元素 [1,2,3,4,5]

 StepVerifier.
                withVirtualTime(() -> Flux.just(1,2,3,4,5).repeatWhen(c -> c.delayElements(Duration.ofSeconds(1)).log()))
                .thenAwait(Duration.ofSeconds(1))
                .expectNext(1)
                .thenAwait(Duration.ofSeconds(4))
                .expectNext(2,3,4,5)

                .thenConsumeWhile(x -> true)   // what is the right behaviour to be added here ? 
    ```

Answer 1

对于“无限”通量，您唯一的选择可能是 thenCancel().verify()
