我在 Vue 框架中使用 jest 来编写联合测试。我的示例测试通过了，但我在记录请求时遇到错误。我该如何解决这个问题？我是在开 Jest 不正确地使用异步吗？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)
    })
})

测试通过时出错

Test Suites: 1 passed, 1 total
Tests:       1 passed, 1 total
Snapshots:   0 total
Time:        1.324 s
Ran all test suites.

  ●  Cannot log after tests are done. Did you forget to wait for something async in your test?

最佳答案

我不是 100% 确定为什么。但切换到 shallowMount 修复了错误。

从 vue 测试工具添加 shallowMount:

import {mount, shallowMount} from '@vue/test-utils';
import Home2 from '@/views/Home2';

然后将mount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 关闭日志记录。所以使用命令 yarn:test --silent
