Inability to use mocks with rxjs

[Raziel]

Hello,

Very nice library, which works well in a lot of cases, except..

Most of my code involves RxJS observables and I can't do something as simple as

const x = mock<T>();
await lastValueFrom(of(x));

It ends with a timeout due to the implementation of of in RxJS.

It seems to boil down to RxJS looking for a schedule property/method on the object passed to of(), and when that property is present RxJS goes down the "wrong" path thinking a scheduler was passed.

There is already a quick fix for promises in the proxy used by jest-mock-extended: https://github.com/marchaos/jest-mock-extended/blob/master/src/Mock.ts#L91

I don't know if it's feasible to add a similar condition for schedule, as it might be a legit property/method in code tested by current users...

Hey - I added a way to add configure global ignores - You can try it on this branch - https://github.com/marchaos/jest-mock-extended/tree/global-config-ignore-props

In your global setup file, you can add

import { JestMockExtended } from 'jest-mock-extended';

JestMockExtended.configure({ ignoreProps: 'schedule '});

You could do that in the test file itself (in the beforeEach, and the do JestMockExtended .configure(JestMockExtended.DEFAULT_CONFIG); in the afterEach

Let me know that helps.

Hello there,

Sorry it took forever, I thought this issue was closed: this solution works just fine 😅
