在Cordova项目上运行Karma时执行0 0 ERROR

标签： cordova requirejs karma-runner

我有一个apache cordova项目设置，我第一次尝试使用Karma。我这样开始了这个项目：

karma start test/karma.conf.js --verbose

但我得到的只是：

INFO [karma]: Karma v0.12.36 server started at http://localhost:9876/
INFO [launcher]: Starting browser Chrome
WARN [web-server]: 404: /favicon.ico
INFO [Chrome 43.0.2357 (Windows 8.1 0.0.0)]: Connected on socket 0_IDnS6qvPg4OhGd7oq4 with id 66015767
Chrome 43.0.2357 (Windows 8.1 0.0.0): Executed 0 of 0 ERROR (0.002 secs / 0 secs)

我已经仔细检查了我对the docs for configuring requirejs for karma做了什么。

karma.conf.js 

module.exports = function(config) {
  config.set({
    basePath: '..',
    frameworks: ['jasmine', 'requirejs'],
    files: [
      {pattern: 'www/lib/ionic/js/*.min.js', included: false},
      {pattern: 'www/lib/ionic/js/angular/*.min.js', included: false},
      {pattern: 'www/lib/ionic/js/angular-ui/*.min.js', included: false},
      {pattern: 'www/js/**/*.js', included: false},
      {pattern: 'test/specs/*Spec.js', included: false},
      {pattern: 'test/test-app.js', included: true}
    ],
    exclude: [
      'www/js/app.js'
    ],
    preprocessors: {
    },
    reporters: ['progress'],
    port: 9876,
    colors: true,
    logLevel: config.LOG_INFO,
    autoWatch: true,
    browsers: ['Chrome'],
    singleRun: false
  });
};

测试app.js 

var tests = [];
for(var file in window.__karma__.files) {
    if(window.__karma__.files.hasOwnProperty(file)) {
        if(/Spec\.js$/.test(file)) {
            tests.push(file);
        }
    }
}

requirejs.config({
    baseUrl: 'www',
    paths: {
        'angular': 'lib/ionic/js/angular'
        ,'angular-ui': 'lib/ionic/js/angular-ui'
    },
    shim: {
        'angular': {exports: 'angular'},
        'www/js/controllers': { deps: ['angular']}
    },
    deps: tests,
    callback: window.__karma__.start
})

helloSpec.js 

define('helloTests', ['angular'], function() {
        describe('UnitTest: Hello', function() {
            it('is defined', function() {
                expect([1,2,3].length).toEqual(3);
            });
        });
    });

这是由此产生的 debug.html ：

我假设服务文档列表是requirejs引入的所有内容，脚本标记是karma添加的内容。

控制台输出是：

Skipped 0 tests

所以看起来它只是看不到测试定义。但是，当我逐步完成调试并在requirejs.config中设置断点时，我可以看到“tests”数组包含我的测试文件：

/base/test/specs/helloSpec.js

通过查看Chrome的网络面板，我也可以看到它已被加载。哪个列表：

debug.html
boot.js
jasmine.js
adapter.js
require.js
test-app.js
adapter.js
helloSpec.js

1 个答案:

答案 0 :(得分：24)

早些时候我收到了错误：

Mismatched anonymous define() module: ...

所以我改变了

的define函数调用 
define(['angular'], function(angular) {
    ....
});

到

define('helloTests', ['angular'], function(angular) {
    ....
});

摆脱了错误细节，但没有解决任何问题。事实证明它也没有帮助，因为我再也看不到错误消息了。发布后，我试着随心所欲地删除它，因为我看不到它在其他任何地方被使用。然后错误消息更改为：

Chrome 43.0.2357 (Windows 8.1 0.0.0) ERROR: 'There is no timestamp for www/lib/ionic/js/angular.js!'

WARN [web-server]: 404: /www/lib/ionic/js/angular.js
Chrome 43.0.2357 (Windows 8.1 0.0.0) ERROR
  Uncaught Error: Script error for: angular
  http://requirejs.org/docs/errors.html#scripterror
  at c:/Users/Mark/AppData/Roaming/npm/node_modules/requirejs/require.js:141

由于我使用的是min文件（通过在文件模式中包含“* .min.js”，更容易过滤出调试版本），我更改了我的requirejs.config路径并附加了“.min”，如下所示：

requirejs.config({
    baseUrl: 'www',
    paths: {
        'angular': 'lib/ionic/js/angular/angular.min'
        ,'angular-ui': 'lib/ionic/js/angular-ui/angular-ui.min'
    },
    ...
})

此时，错误消息仅更改为表示angular.min.js没有时间戳。在这一点上，我注意到路径是相对的，并以“base / wwww”开头。就在那时我终于发现了一些我错过的东西in the docs。所以我更改了requirejs.config中的“baseUrl”参数以添加“base /”：

requirejs.config({
    baseUrl: 'base/www',
    ...
})

现在错误消失了，测试正在运行：

Chrome 43.0.2357 (Windows 8.1 0.0.0): Executed 1 of 1 SUCCESS (0.015 secs / 0 secs)

编辑：还有一件事，测试开始运行，但我没有注意到我仍然收到“没有时间戳”的消息。将requirejs.config baseUrl参数从relative更改为绝对（将“/”添加到开头）修复它。 

requirejs.config({
    baseUrl: '/base/www',
    ...
})

现在我已经开始运作了。
