您的测试套件必须至少包含一项测试

本文介绍了您的测试套件必须至少包含一项测试的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我今天在我的项目中更新了一些依赖项，但它进行得非常顺利.现在，当我要推动它时，我开始了我的测试.和繁荣.他们都扔了:

I have updated some of the dependencies today in my project, but it went through really smoothly. Now, when I'm about to push it, I started my tests. And boom. All of them throw:

您的测试套件必须至少包含一个测试.

我的包裹:

"jest": "23.1.0",
"jest-enzyme": "^6.0.1",
"jest-webpack-alias": "^3.3.3",
"jsdom": "^11.2.0",
"jsdom-global": "^3.0.2",
"enzyme": "3.3.0",
"enzyme-adapter-react-16": "^1.1.0",
"enzyme-to-json": "3.3.4",

这就是我的示例测试文件的样子:

And that is how my sample test file looks like:

/shared/components/App/MyRoute/__tests__/MyRoute.test.js

/* eslint-disable import/no-extraneous-dependencies */
import React from 'react';
import { shallow } from 'enzyme';
import { ContactsRoute } from '../Route';

describe('<ContactsRoute />', () => {
  test('renders', () => {
    const wrapper = shallow(<ContactsRoute t={key => key} />);
    expect(wrapper).toMatchSnapshot();
  });
});

我不知道他们为什么突然停止跑步?

I have no idea why they stopped running so suddenly?

编辑 - 添加我的笑话配置

  "jest": {
"collectCoverageFrom": [
  "shared/**/*.{js,jsx}"
],
"globals": {
  "JWT_SECRET": "local",
  "IS_TEST": "true"
},
"snapshotSerializers": [
  "<rootDir>/node_modules/enzyme-to-json/serializer"
],
"testPathIgnorePatterns": [
  "<rootDir>/(build|internal|node_modules|flow-typed|public|shared/services)/"
],
"moduleNameMapper": {
  "\.(jpg|jpeg|png|gif|eot|otf|webp|svg|ttf|woff|woff2|mp4|webm|wav|mp3|m4a|aac|oga)$": "<rootDir>/_test_config_/mocks/fileMock.js"
},
"testURL": "http://localhost:3005",
"transform": {
  ".": "<rootDir>/_test_config_/preprocessors/webpackAlias.js",
  "^.+\.css$": "<rootDir>/_test_config_/preprocessors/cssTransform.js",
  "^(?!.*\.(js|jsx|css|json)$)": "<rootDir>/_test_config_/preprocessors/fileTransform.js"
},
"setupFiles": [
  "<rootDir>/_test_config_/preprocessors/polyfills.js"
],
"setupTestFrameworkScriptFile": "./node_modules/jest-enzyme/lib/index.js"
},

确保未导入 describe/it/expect 变量

就我而言，IDE(VSCode)会自动从另一个库中导入变量 describe.
