我正在尝试为 VueJS 组件编写我的第一个单元测试,该组件在呈现时从 API 端点获取一些数据:
我的 VueJS 组件:
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;
})
},
}
和我的测试:
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" : "[email protected]",
"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="">[email protected]</td>');
done();
});
});
});
所以我期望发生的是组件被实例化,然后它执行一个 API 调用,它被 Moxios 捕获,之后它应该执行
moxios.wait
,这没有发生。测试似乎忽略了 moxios.wait
,即使它不应该成功通过。我在这里缺少什么?
最佳答案
尝试添加 done
作为参数:
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="">[email protected]</td>');
done();
});
});
等待 Ajax
更改如下:
// 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": "[email protected]",
"first_name": "Kenneth",
"last_name": "Connelly"
}]
}
}).then(function() {
expect(wrapper.html()).toContain('<td class="">[email protected]</td>');
done();
});
});
});
关于vue.js - `moxios.wait` 在使用 Jest、Vue Test Utils 和 Moxios 测试 VueJS 时从不执行,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/49130579/
