`moxios.wait` never executes when testing VueJS with Jest, Vue Test Utils and Moxios - vue.js

Question

I'm trying to write my first unit test for a VueJS component that grabs some data from an API endpoint when it renders:
My VueJS component:
import axios from 'axios';
export default {
props: {
userIndexUrl: {
required: true
}
},
data() {
userList: [],
tableIsLoading: true
},
created() {
const url = this.userIndexUrl;
axios.get(url)
.then(response => {
this.userList = response.data.data;
this.tableIsLoading = false;
})
},
}
and my test:
import { mount } from 'vue-test-utils'
import moxios from 'moxios'
import UsersAddRemove from 'users_add_remove.vue'
describe('UsersAddRemove', () => {
const PROPS_DATA = {
userIndexUrl: '/users.json'
}
beforeEach(() => {
moxios.install();
moxios.stubRequest('/users1.json', {
status: 200,
response: {
"count": 1,
"data": [
{ "id" : 1,
"email" : "brayan#schaeferkshlerin.net",
"first_name" : "Kenneth",
"last_name" : "Connelly"
}
]
}
});
});
afterEach(() => {
moxios.uninstall();
});
it('loads users from remote JSON endpoint and renders table', () => {
const wrapper = mount(UsersAddRemove, { propsData: PROPS_DATA });
moxios.wait(() => {
expect(wrapper.html()).toContain('<td class="">brayan#schaeferkshlerin1.net</td>');
done();
});
});
});
So what I expect to happen is the component gets instantiated, after which it does an API call, which is caught by Moxios, after which it should execute moxios.wait, which isn't happening. The tests seem to ignore moxios.wait, and it passes successfully even when it shouldn't.
What am I missing here?

Try adding the done as argument:
it('loads users from remote JSON endpoint and renders table', (done) => {
// -----------------------------------------------------------^^^^^^
const wrapper = mount(UsersAddRemove, { propsData: PROPS_DATA });
moxios.wait(() => {
expect(wrapper.html()).toContain('<td class="">brayan#schaeferkshlerin1.net</td>');
done();
});
});
Waiting for the Ajax
Change as follows:
// remove the stubRequest of beforeEach()
beforeEach(() => {
moxios.install();
});
// afterEach stays the same
it('loads users from remote JSON endpoint and renders table', (done) => {
const wrapper = mount(UsersAddRemove, { propsData: PROPS_DATA });
moxios.wait(() => {
let request = moxios.requests.mostRecent();
request.respondWith({
status: 200,
response: {
"count": 1,
"data": [{
"id": 1,
"email": "brayan#schaeferkshlerin.net",
"first_name": "Kenneth",
"last_name": "Connelly"
}]
}
}).then(function() {
expect(wrapper.html()).toContain('<td class="">brayan#schaeferkshlerin1.net</td>');
done();
});
});
});
