我试图学习测试一些JavaScript文件。在webpack中使用mocha和chai。单元测试Javascript - 对象不是构造函数
这是我test/karma.conf.js
var webpack = require('webpack');
module.exports = function (config) {
config.set({
browsers: [ 'PhantomJS' ],
singleRun: true,
frameworks: [ 'mocha' ],
files: [
'tests.webpack.js'
],
preprocessors: {
'tests.webpack.js': [ 'webpack', 'sourcemap' ]
},
reporters: [ 'spec' ],
webpack: {
devtool: 'inline-source-map',
module: {
loaders: [
{ test: /\.js$/, loader: 'babel-loader' }
]
}
},
webpackServer: {
noInfo: true
}
});
};
这是我的人缘配置使用test/test.webpack.js
:
import chai from 'chai'
global.chai = chai
global.expect = chai.expect
global.should = chai.should()
var context = require.context('../src', true, /spec\.js$/);
context.keys().forEach(context);
我的测试是非常基本的,只是为了测试它是否工作src/index.spec.js
:
describe("A test suite", function() {
beforeEach(function() { });
afterEach(function() { });
it('should fail', function() { expect(true).to.be.true; });
});
当我尝试运行测试时,我得到了这个错误
./node_modules/karma/bin/karma start test/karma.conf.js

不应该'global.should = chai.should()'是'global.should = chai.should'? – henry700
@ henry700不应该是正确的 – tyler
错误消息指出您的webpack配置有错误。你也可以发布吗? – Charminbear
