Mocking this.$q.notify results in TypeError: this.$q.notify is not a function

Open khteh opened this issue 3 years ago • 1 comments

I am trying to mock the this.$q.notify but have not had any luck. I have asked in Discord but no response.

beforeEach(() => {
    wrapper = mount(CartView, {
      global: { plugins: [Store], provide: qLayoutInjections() },
      mocks: {
        $q: {
          notify: jest.fn()
       },
      }
    });
});

And get this error during test:

          this.$q.notify({
                  ^

TypeError: this.$q.notify is not a function

How can I successfully mock this.$q.notify? Thanks.

I make some changes w.r.t https://test-utils.vuejs.org/migration/#mocks-and-stubs-are-now-in-global

    wrapper = mount(CartView, {
      global: { 
        plugins: [Store], 
        provide: qLayoutInjections(),
        mocks: {
          $q: {
            notify: jest.fn()
          }
        }
      }
    });

and the test crashes:

Still doesn't work for Quasar 2.11.5, Vitest 0.27.1 and "@quasar/quasar-app-extension-testing-unit-vitest": "^0.1.2". I added injections from here and did this:

it('mock a dummy call', async () => {
    const wrap = mount(Dummy, {
      global: {
        provide: qLayoutInjections(),
        mocks: {
          $q: {
            notify: vi.fn(),
          },
        },
      },
    });

    expect(wrap.html()).toContain('Dummy');
    await formInput = wrap.get('[data-test=form-top]').trigger('submit');
    console.log(wrap.emitted());
  });
});

Getting the same error:

 FAIL  test/sfc/dummy.spec.ts > Dummy Component > mock a dummy call

Please provide a repro, I don't have the time to reproduce the problem by trial and errors Also, the issue author was apparently referring to a Jest problem (can't be sure, he didn't mention it), while your is a Vitest problem

I solved this problem by mocking $q stuff and forgot about it long ago. Sorry, can't reproduce it anymore :smile_cat:

drev74 avatar Mar 01 '23 11:03 drev74

Thanks for the update! Closing this one then Can you share how you mocked $q stuff successfully?

@IlCallo i did it like this in our nuxt project setup file

installQuasarPlugin({ plugins: { Notify } });

test file:

  const notify = vitest.fn();

  const wrapper = shallowMount(MyComponent, {
    global: {
      provide: {
        _q_: { notify },
      },
    },
  });
// Trigger notify somehow
expect(notify).toHaveBeenCalled();

I am currently looking for a clean solution to test Quasar components in a Nuxt 3 project. How have you integrated quasar-testing into your Nuxt code base?

I would appreciate a short feedback.

Best
