How to test the components that uses vuex with injection key

[tomocrafter]

since useStore function of vuex accpets injection key for typing the store, but vue-test-utils-next only accepts plugins.
Is there any way to specify injection key for store?

(If I call useStore in component's setup on test, it will return undefined because injection key is not registered correctly. it works if not in test though)

I completely overlooked that https://next.vue-test-utils.vuejs.org/api/#global plugins options accepts arguments if passed it with array.

I usually use provide when I mount the component to register a fake store (or the real one) with the correct key:

const wrapper = mount(AppWithVuex, { global: { provide: { [myStoreKey]: store } } });
