Question

每当我运行单元测试时，我都会收到错误：

browser is not defined.

我的配置文件在下面 - 任何人都可以提出问题

module.exports = function (config) {
config.set({
    // base path that will be used to resolve all patterns (eg. files, exclude)
    basePath: './',


    // frameworks to use
    // available frameworks: https://npmjs.org/browse/keyword/karma-adapter
    frameworks: ['jasmine'],


    // list of files / patterns to load in the browser
    files: [

    autoWatch: true,


    // start these browsers
    // available browser launchers: https://npmjs.org/browse/keyword/karma-launcher
    browsers: ['Chrome', 'Firefox', 'IE'],


    // Continuous Integration mode
    // if true, Karma captures browsers, runs the tests and exits
    singleRun: false,

    // Concurrency level
    // how many browser should be started simultaneous
    concurrency: Infinity

要实际打开浏览器实例，Karma需要一个浏览器启动器，它以插件的形式出现。

来自Karma's browser docs：

注意：大多数浏览器启动器都需要作为插件加载。

您是否安装了正确的启动器插件？

使用Karma / Jasmine进行角度单元测试 - 未定义浏览器
