Question

我们最近升级到Angular 6.0.3，RxJs 6.2.0和jest 23.1.0（从RxJS 5和Angular 4升级）。

Jest＆RxJs似乎存在问题，因为在subscribe-Block中失败的期望语句不会将测试标记为失败。这是一个最小的示例：

    it("should fail", () => {

        const obs = Observable.create((observer) => {
            observer.next(false);
        });

        obs.subscribe((value) => {
            console.log(value); // => false
            expect(value).toBeTruthy();
        });

    });

expect-Statement被执行，但是测试仍然通过。在以前的RxJs版本和Jest中，我们没有观察到这种行为。
