Testing component injected with mobx store

[tag6071]

Hi, I appreciate the awesome work done to birth this package.

I have been trying to test an angular component which has a mobx store injected into it but I can't seem to get a way to mock the mobx store such that I can dynamically change the values returned by some methods in the store. with ng-redux I can do something like MockNgRedux.getSelectorStub(selectorComponent) to stub out the selector.

So i'll like to know if there is a way this can be done when testing a component which makes use of mobx-angular

Hi,
Thanks for the kind words :)
This sounds like a general Angular question. A store is just a regular Injectable, so you can mock it anyway you'd like. I don't see how it's specific to MobX / mobx-angular.

So depending on which testing library you use, Jeft/Jasmine etc. - you can use stubs/spies to create a mock store, and configure it in Angular's TestBed:
