TypeError: Cannot read property 'getters' of undefined

Hi,

I’m facing an issue here with TypeScript when I want to unit test my module.

My index.ts for my store:

import { StoreOptions } from 'vuex';
import { EndUsersModule } from './end-user-module';

const store: StoreOptions<{}> = {
  modules: {
    endUsers: EndUsersModule,
  },
};

My end-user-module.ts:

import { Action, Module, Mutation, VuexModule } from 'vuex-module-decorators';
import { EndUser } from './models';
import store from '@/shared/store'

@Module({
  dynamic: true,
  name: 'endUsers',
  store,
})
export class EndUsersModule extends VuexModule {
  private users: EndUser[] = [];
  
  public get endUsers() {
    return this.users;
  }
  
  @Action
  public async createEndUser(user: EndUser) {
    this.context.commit('createUserStart');
    
    try {
      await api.createUser(user);
      this.context.commit('createUserSuccess', user);
    } catch (err) {
      this.context.commit('createUserFail', err);
    }
  }
  
  @Mutation
  public createEndUserFail(err: any)         { /* implementation */ }
  @Mutation
  public createEndUserStart()                { /* implementation */ }
  @Mutation
  public createEndUserSuccess(user: EndUser) { /* implementation */ }
}

Now, I want to test the action createEndUser, but my problem is that when I do this at the top of my file:

import { EndUsersModule } from './end-user-module';
import { createModule } from 'vuex-module-decorators';

const endUsers = getModule(EndUsersModule);

describe('...', () => {
  // ...
});

And run my tests, I see the following error message:

TypeError: Cannot read property 'getters' of undefined

Can you please tell me how I can unit test my actions, or the whole module for that matter?

I was also trying to do it with vuex-class, but that also has its complications for actions. Then, I found your library, and I thought everything should be fine now, but that’s not the case 😦

I just ran into this as well. Seems like there is no example on the internet on how to successfully unit test while using vuex-module-decorators.

I mean these my friend,

These are actual projects

These example repos even don’t have real tests scenario, my friend. Take a look yourself.
