Current behavior

I'm trying to do some polling-like logic with a test, so I use a fakeAsync with tick() in the Jasmine test. But calling tick() does not resolve all asynchronous functions that is created during passage tick time.

Expected/desired behavior

tick() function should also resolve all the asynchronous functions that is created and should be executed during that time.

Reproduction of the problem

Here is the sample test:

it('tick should behave correctly', fakeAsync(() => {
    let counter = 0;
    const runner = () => {
        counter++;
        if (counter < 10) {
            setTimeout(() => runner(), 10);
        }
    };
    runner();
    tick(10000);
    expect(counter).toEqual(10);
}));

The test failed with 2 errors:

• Expected 2 to equal 10.
• Error: 1 timer(s) still in the queue.

What is the expected behavior?

The test should passes.

Current workaround for me is to use

for (let i = 0; i < 10000; i++) tick(1);

instead, which seems weird to me.
