I'm getting the same error when mounting a component with v-date-picker in it.
For me a __dirty__ temporary workaround was to use global Vue. No idea why, but it works. It seems to be an issue on vuetify's side.

Interesting......

Can you give me an example or link to see how to use a global vue for the dirty workaround, please?

Just updated your test:

import { mount, createLocalVue } from "@vue/test-utils";
import Vue from "vue";
import Vuetify from "vuetify";
import TestComponent from "./TestComponent.vue";

Vue.use(Vuetify);

describe("TestComponent", () => {
  beforeEach(() => {
  });

  it("Mount", () => {
    const wrapper = mount(TestComponent);
    expect(wrapper.contains(".v-input.v-text-field")).toBeTruthy();
  });

  it("THEN should have a label", () => {
    const wrapper = mount(TestComponent);
    expect(wrapper.props().label).toBeDefined();
  });
});

This is an issue with Vuetify not being able to be installed on multiple Vue constructors, which means you can't use the localVue pattern. I believe this will be changed in Vuetify 2.0. Closing this since I don't think we can fix this issue on our end.
