Hi so this might not work for every scenario, but in this case I was overthinking it. I was able to get the tests I needed by just setting the global state to my test values right in the beginning of my test. It's a "set" not a "mock" but it works.

@k-patton I have exposed the getGlobalState
and getState
at the window
level - so I can actually call window.getGlobalState()
(for example) and see a console log of things. You could use those to create your own dev
panel in your application as well. Kent Dodds has some interesting examples of using his testing-library
for doing things like that... https://kentcdodds.com/blog/make-your-own-dev-tools/

Hi, I have same problem, and found the way to resolve it.
In my Code...
// AComponent.tsx
...
export const { dispatch, useGlobalState } = createStore(reducer, initialState);
// BComponent.tsx
import { useGlobalState } from './AComponent';
...
{
const [test, setTest] = useGlobalState('test')
}
So, my solution is like that,
mock that import module
const initialState: MyState = {
test: {}
};
const { setGlobalState, useGlobalState } = createGlobalState(initialState);
jest.mock('./AComponent', () => {
return {
useGlobalState: jest.fn().mockImplementation((args) => useGlobalState(args))
};
})
within the test code, we can modify that state with setGlobalState
...
test('test', () => {
...
setGlobalState('test', {value: true});
const wrapper = mount(<BComponent>);
// then check the component itself.
I want this will help you, @k-patton

Hi, that's a good question. I'm not super experienced with mocking, so I wish someone else would jump in this topic.
What I would imagine is to a) mock the hook at module level, or b) use another createGlobalState for testing.

On another testing note, has anyone heard of a way to see the current state of the store? Kind of like redux dev tools?
from react-hooks-global-state.
It does support redux devtools with createStore
.
It should work for basic functionality.
Speaking of devtools, I maintain another library zustand which is similar to react-hooks-global-state, but more flexible (because I made react-hooks-global-state to provide api that will never be misused, it's limited in a sense.) Just yesterday, I fixed the devtools module in zustand, which should be more stable. It's not released yet, but you might want to have a look.

also - we have just taken a similar approach in our Jest testing.
We actually wrap a lot of functions in an "api" - including the useGlobalState
- so we can initialise the global state with anything we want in our tests (including using all our default state).

v2 is released and closing this.
