Jest“测试完成后无法登录。您忘记在测试中等待异步的东西了吗？”
提问于 2021-07-23 19:04:56
我正在用jest与Vue框架，编写联合测试。我的示例测试正在通过，但是我记录请求时出错了。我该如何解决这个问题？我是不是在开玩笑中不正确地使用异步？下面是测试的副本，下面是错误。
测试
describe('Home', () => {
test('Example Test', async () => {
// Arrange - Mounts the component so we can test it. And chooses what we are going to test in the component
const wrapper = mount(Home2)
// Act - Does something to the component
// Assert - Checks to see if what we did to the component matches what we want it to do
expect(wrapper.html()).toContain(0)
})
})错误与测试通过

我不能百分之百确定原因。但是切换到shallowMount修复了错误。
从vue测试实用程序中添加shallowMount：
import {mount, shallowMount} from '@vue/test-utils';
import Home2 from '@/views/Home2';然后将mount更改为shallowMount
describe('Home', () => {
test('Example Test', async () => {
// Arrange - Mounts the component so we can test it. And chooses what we are going to test in the component
const wrapper = shallowMount(Home2)
// Act - Does something to the component
// Assert - Checks to see if what we did to the component matches what we want it to do
expect(wrapper.html()).toContain(0)
})
})您也可以通过运行--silent来关闭日志记录。因此，使用命令yarn:test --silent运行您的测试
