Initial value test with BehaviorSubject fails

Hi,

I have been trying to use jasmine-marbles in an Angular project but the following test is failing:

it('works', () => {
  const foo = new BehaviorSubject(1);
  const expected = cold('a', { a: 1 });
  
  expect(foo).toBeObservable(expected);
});

The error is as follows:

Error:
    Expected: a,
    Received: ?,

    Expected:
    [{"frame":0,"notification":{"kind":"N","value":1,"hasValue":true}}]

    Received:
    [{"frame":0,"notification":{"kind":"N","value":1}}],

The same test using TestScheduler as follows works:

const foo = new BehaviorSubject(1);

scheduler.run((helpers) => {
  helpers.expectObservable(foo).toBe('a', { a: 1 });
});

Any suggestions?

@qdelettre My bad, I confirm this works fine when downgrading to 0.8.3.

0.2.0 supports RxJS 5.x => 0.3.* supports RxJS 6.x => 0.9.0 supports RxJS 7.x

You cannot use 0.9.0 with rxjs < 7
