我有一个ES6项目,我使用webpack将客户端代码转换为ES5.该项目在客户端使用ReactJS,因此,单元测试自然会使用React TestUtils.在最新的更新(0.14)中,React 更改了几个模块的导入方式(包括TestUtils).我想更新,但我无法弄清楚如何在更改导入后使单元测试工作.
当我尝试运行测试时,我收到以下消息:
04 12 2015 12:40:48.038:ERROR [karma]: { [Error: no such file or directory] code: 'ENOENT', errno: 34, message: 'no such file or directory', path: '/_karma_webpack_/public/test/main.js' } Error: no such file or directory at MemoryFileSystem.readFileSync (/node_modules/karma-webpack/node_modules/webpack-dev-middleware/node_modules/memory-fs/lib/MemoryFileSystem.js:107:10) at MemoryFileSystem.readFile ( /node_modules/karma-webpack/node_modules/webpack-dev-middleware/node_modules/memory-fs/lib/MemoryFileSystem.js:297:21) at doRead ( /node_modules/karma-webpack/index.js:156:26) at Plugin.readFile ( /node_modules/karma-webpack/index.js:160:3) at doNTCallback0 (node.js:419:9) at process._tickCallback (node.js:348:13) Hash: dee787e2bee8303745db Version: webpack 1.12.9 Time: 3657ms Asset Size Chunks Chunk Names public/test/main.js 1.71 MB 0 public/test/main.js 5044d04bf14a5de57d08.hot-update.json 35 bytes chunk {0} public/test/main.js (public/test/main.js) 1.6 MB [rendered] [0] ./public/test/main.js 176 bytes {0} [built] [1] ...

在我的tests_auth.jsx和test_modal.jsx文件中,我开始以下导入:
import React from 'react'; import ReactDOM from 'react-dom'; import TestUtils from 'react-addons-test-utils';
我的package.json中的测试脚本是:
PHANTOMJS_BIN=./node_modules/.bin/phantomjs && ./node_modules/karma/bin/karma start karma.config.js
我的相关依赖是:
"devDependencies": { "chai": "^3.4.1", "chai-as-promised": "^5.1.0", "coveralls": "^2.11.4", "karma": "^0.13.9", "karma-chai": "^0.1.0", "karma-chai-as-promised": "^0.1.2", "karma-chai-plugins": "^0.6.1", "karma-coverage": "^0.5.2", "karma-mocha": "^0.2.0", "karma-phantomjs-launcher": "^0.2.1", "karma-sinon-chai": "^1.0.0", "karma-webpack": "^1.7.0", "mocha": "^2.3.3", "phantomjs": "^1.9.18", "react-hot-loader": "^1.3.0", "webpack-dev-server": "^1.10.1" }, "dependencies": { "react": "0.14.3", "react-dom": "0.14.3", "webpack": "^1.12.1" }
我的karma.config.js是:
var webpack = require('webpack'); module.exports = function(config) { 'use strict'; config.set({ files: [ './public/test/polyfill.js', './public/test/main.js' ], preprocessors: { './public/test/main.js': [ 'webpack' ] }, browsers: [ 'PhantomJS' ], frameworks: [ 'mocha', 'sinon-chai', 'chai-as-promised', 'chai' ], reporters: [ 'progress', 'coverage' ], coverageReporter: { dir: 'coverage/', reporters: [ { type: 'lcovonly', subdir: '.', file: 'lcov.info' }, { type: 'html', subdir: 'html' } ] }, webpack: { plugins: [ new webpack.HotModuleReplacementPlugin(), new webpack.NoErrorsPlugin() ], module: { loaders: [ { test: /\.jsx?$/, exclude: /node_modules/, loader: 'babel-loader?stage=0' } ] }, resolve: { extensions: [ '', '.js', '.jsx' ], modulesDirectories: [ 'node_modules', 'public/src', 'public/test' ] } }, webpackMiddleware: { noInfo: true }, singleRun: true, plugins: [ 'karma-mocha', 'karma-webpack', 'karma-coverage', 'karma-sinon-chai', 'karma-chai', 'karma-chai-plugins', 'karma-chai-as-promised', 'karma-phantomjs-launcher' ] }); };
最后,我的文件结构如下所示:
karma.config.js package.json node_modules/ public/ app.js index.html src/ main.jsx test/ main.js polyfill.js pages/ test_auth.jsx common/ test_modal.jsx
我显然有一些配置错误,但我在弄清楚它是什么时遇到了很多麻烦.有谁遇到过类似的问题?更熟悉Karma,Webpack或React 0.14的人是否知道我错了什么?
我现在觉得很蠢.我忘了在我的package.json中添加'react-addons-test-utils'.
