Unit testing a component with QPageSticky

[arfarf]

I’m trying to write a test using jest for a component that looks like this:

<template>
  <q-page-sticky
    position="top"
    expand
    class="bg-secondary text-base"
  >
    <q-toolbar dense>
      <q-btn
        v-if="hasBackBtn"
        flat
        round
        dense
        icon="chevron_left"
      />
      ...
    </q-toolbar>
  </q-page-sticky>
</template>

Mounting this component in test logs out QPageSticky needs to be child of QLayout error in console.

describe('Foo.vue', () => {
  const localVue = createLocalVue();
  localVue.use(Quasar, { components });
  // error in mount
  const wrapper = mount(Foo, {
    localVue,
    propsData: {
      hasBackBtn: false,
      title: 'Title',
    },
  });
  const { vm } = wrapper;
  ...

Making a temporary component and passing it to parentComponent field in mount() still didn’t work.

const parentQLayout = {
  name: 'parentQLayout',
  template: '<q-layout></q-layout>',
};

describe('Foo.vue', () => {
  const localVue = createLocalVue();
  localVue.use(Quasar, { components });

  const wrapper = mount(Foo, {
    localVue,
    parentComponent: parentQLayout,
    propsData: {
      hasBackBtn: false,
      title: 'Title',
    },
  });
  const { vm } = wrapper;

This component is used inside parent component that has QLayout in actual source code btw. Is there any way to test a component with QPageSticky independently given its QLayout restriction?
