TestScheduler RxTest 4.2 RxSwift 4.2

如何正确地创建TestScheduler并向其传递在所有事件执行后终止调度器的事件?

下面的代码在启动测试调度器时进入无限循环。因为它保持同步循环,所以我没有机会阻止调度器进行测试

    var testScheduler: TestScheduler = TestScheduler(initialClock: 0)

    let stateObserver = testScheduler.createObserver(Bool.self)
    subject.outputRelay.bind(to: stateObserver).disposed(by: bag)

    let events = [next(1,true), next(10,false)]
    let hotObservable = testScheduler.createHotObservable(events)

    //direct events to the given relay
    hotObservable.bind(to: subject.inputRelay).disposed(by: bag)

    testScheduler.start() //infinite loop

//do not get called
    XCTAssertEqual(stateObserver.events, [next(0, InterfaceState.started)])
    testScheduler.stop()

我已经将发布的范围缩小到了 测试调度器

 func findNext() -> VirtualSchedulerItem<VirtualTime>? {
        while let front = _schedulerQueue.peek() {
            if front.isDisposed {
                //this never gets called
                _schedulerQueue.remove(front)
                continue
            }

            return front
        }

        return nil
    }
