javascript - Karma/Chrome 的警告和错误

Question

现在正在通过 O'Reilly 的《AngularJS Up and Running》一书学习 AngularJS。 进入了有关 Karma 和 Jasmine 单元测试的章节，但无法使其正常工作

编辑:将 logLevel 更改为 config.LOG_DEBUG 现在可以正确匹配文件模式。但最后我仍然遇到最终的“适配器”错误。

运行“karma start”命令会给出以下内容:

因此，首先它会警告查找文件，但所有这些文件确实存在于该位置。

我的 karma.conf.js 文件如下所示:

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

    // testing framework to use (jasmine/mocha/qunit/...)
    frameworks: ['jasmine'],

    // list of files / patterns to load in the browser
    files: [
      'angular.min.js',
      'angular-mocks.js',
      'controller.js',
      'simpleSpec.js',
      'controllerSpec.js'
    ],

    // list of files / patterns to exclude
    exclude: [],

    // web server port
    port: 8080,

    // level of logging
    // possible values: LOG_DISABLE || LOG_ERROR ||
    //                  LOG_WARN || LOG_INFO || LOG_DEBUG
    logLevel: config.LOG_DEBUG,


    // enable / disable watching file and executing tests
    // whenever any file changes
    autoWatch: true,

    // Start these browsers, currently available:
    // - Chrome
    // - ChromeCanary
    // - Firefox
    // - Opera
    // - Safari (only Mac)
    // - PhantomJS
    // - IE (only Windows)
    browsers: ['Chrome'],


    // Continuous Integration mode
    // if true, it capture browsers, run tests and exit
    singleRun: false
  });
};

karma 安装在我的项目文件夹中(karma.conf.js 所在的位置)

我真的不知道出了什么问题，也找不到联系这本书的作者的方法。谢谢!

我也面临着同样的问题，我的思绪快要爆炸了。我在任何地方都找不到任何东西，所有配置都正常，似乎没有任何问题。你的问题是我能找到的最接近的问题。

我意识到你的项目文件路径和我的项目文件路径都包含方括号(.../[lab]/... 在你的项目文件路径中)，这可能是原因。众所周知，特殊角色有时会很麻烦。

我从文件路径中删除了方括号，所有测试都完美运行。

如果你注意调试行，jasmine.js 和adapter.js 没有被解析。

希望这能对您有所帮助。
