angularjs - Karma 测试运行器和闭包库 "NOT SERVED FILE"

Question

我们在共享代码的几个不同项目中使用闭包库。我们现在正在其中一个项目中启动 AngularJS，并尝试让 Karma 运行器正常工作。

我已遵循这篇文章的建议，但无法让它完全正常工作。 How to configure karma-runner (also known as testacular) to work with closure-library

它正在工作 goog.require('my.namespaced.file') 但当 my/namespaced/file.js 有 goog.require('goog.dom') 或闭包库中的某些内容时，Karma 运行程序吐出这个...

这是我的 karma.conf.js 文件

basePath = '../../../../';

// frameworks to use
frameworks = ['jasmine', 'closure'];

// list of files / patterns to load in the browser
files = [
 // closure base
 {pattern: 'closure-library/closure/goog/base.js', watched: false, included: true, served: true},
 {pattern: 'ne-js/src/main/js/ne-js.deps.js', watched: false, included: true, served: true},

 {pattern: 'webapp/src/main/js/**/*.js', watched: true, included: false, served: true},
 {pattern: 'webapp/src/test/js/**/*.js', watched: true, included: true, served: true},
];

preprocessors = {
 'webapp/src/test/js/**/*.js': ['closure', 'closure-iit'],
 'webapp/src/main/js/**/*.js': ['closure'],
};

autoWatch = true;
browsers = ['Chrome'];

// plugins to load
plugins = [
 'testacular-closure',
 'karma-jasmine',
 'karma-chrome-launcher',
 'karma-phantomjs-launcher',
];

tl；博士；您需要将 {pattern: 'lib/goog/deps.js',included: false,served: false} 添加到您的文件列表，其中 lib/goog/deps.js 是您的 Closure-library 版本中 deps.js 文件的路径。

好吧，所以我深入研究了 Karma Web 服务器和 Karma 关闭插件并发现了问题。

问题出现在 web-server.js 的第 103 行，原因是缺少文件依赖项。目前，karma-closure 插件在缺少依赖项时不会报告错误，而是添加路径为 undefined 的文件指针，最终导致 web-server.js 文件崩溃(这就是您所看到的)。

就我而言，我错过了对所有文件进行预处理，因此我的项目依赖项之一没有被映射，导致它崩溃。在您的情况下，您似乎缺少关闭 deps.js 文件。如果您注意到 the demo conf file您需要手动包含闭包库 deps.js 文件。如果没有此文件，则不会映射闭包提供的 namespace (goog.dom 等)。

我还添加了 pull request在 GitHub 上添加缺少依赖项的错误消息，而不是让 web-server.js 崩溃。
