我有一个 apache cordova 项目设置，我是第一次尝试使用 Karma。我是这样开始这个项目的:
karma start test/karma.conf.js --verbose
但我得到的是:
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)
我已经根据 the docs for configuring requirejs for karma 仔细检查了我所做的事情.
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
});
};
test-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);
});
});
});
这是生成的debug.html:

},

return;

var msg = result.success ? 'SUCCESS ' : 'FAILED ';

我假设所提供的文档列表是由 requirejs 拉入的所有内容，而脚本标签是由 karma 添加的内容。
控制台输出为:
Skipped 0 tests
所以看起来它只是没有看到测试定义。但是当我单步调试并在 requirejs.config 处设置断点时，我可以看到“tests”数组包含我的测试文件:
/base/test/specs/helloSpec.js
我还可以通过查看 Chrome 的网络面板来看到它已加载。其中列出:
debug.html
boot.js
jasmine.js
adapter.js
require.js
test-app.js
adapter.js
helloSpec.js
最佳答案
早些时候我收到了错误:
Mismatched anonymous define() module: ...
所以我改变了定义函数调用
define(['angular'], function(angular) {
....
});
至
define('helloTests', ['angular'], function(angular) {
....
});
这消除了错误详细信息，但没有修复任何问题。事实证明它也没有帮助，因为我再也看不到错误消息的变化。发布后，我一时兴起尝试将其删除，因为我看不到它在其他地方使用。然后错误信息变为:
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
由于我使用了 min 文件(通过在文件模式中包含“*.min.js”更容易过滤掉调试版本)，我更改了 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 angular.min.js 没有时间戳。此时我注意到路径是相对的并以“base/wwww”开头。就在那时，我终于注意到了我错过的一些东西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”消息。将我的 requirejs.config baseUrl 参数从相对更改为绝对(在开头添加“/”)修复了它。
requirejs.config({
baseUrl: '/base/www',
...
})
现在我已经启动并运行了。
