Do no reset every mock, when calling resetSpyMsal()

[anotherHoffmann]

When calling resetSpyMsal(), every mock of the test-runner is reset, which causes issues when one is also mocking other functionality than MSAL.

resetSpyMsal() {
    this._testRunner.resetAllMocks();
    this.accounts = [];
    this.activeAccount = null;
    this._eventCallbacks = [];
}

Is there a possibility to only reset mocks related to MSAL?

No Idea, maybe some options in the testRunner ?

Any time this._testRunner.spyOn() is called, the spy return value should be stored in some sort of instance cache, then resetSpyMsal() loops through this cache and calls .mockReset() on each spy present. Many calls to spyOn() are already cached in "private" instance properties, so the bulk of the work would be figuring out the best caching approach (this._spies = new Map<string, jest.Spied<unknown>>(), a private _createSpy(obj, methodName): jest.Spied<typeof obj[methodName]> method that could do the Map bookkeeping, _getSpy(methodName): jest.Spied<unknown> to simplify retrieval inside various assertions, and so on).

Sounds interesting
Thanks a lot @evocateur
