我正在尝试为我的控制器运行单元测试用例，我尝试了以下但是得到以下错误，请让我知道成功运行此测试。提前谢谢。
spec.js：
describe('MainCtrl', function() {
beforeEach(module('app-module'));
var $controller;
beforeEach(inject(function(_$controller_){
$controller = _$controller_;
}));
describe('$scope.titleofapp', function() {
var $scope, controller;
beforeEach(function() {
$scope = {};
controller = $controller('MainCtrl', { $scope: $scope });
});
it('sets the title of app to "app-module" module', function() {
$scope.titleofapp();
expect($scope.title).toEqual('My Test App !');
});
});
});
app.js：
define(['angular', './app-module'], function(angular, appModule) {
'use strict';
return appModule.controller('MainCtrl', ['$http', '$q', 'appService', '$stateParams', function($http, $q, $stateParams, appService){
$scope.titleofapp = function(){
$scope.title = 'My Test App !';}
}]);
});
下面是我的karma.conf.js文件配置：
karma.conf.js：
module.exports = function(config) {
config.set({
basePath: '',
frameworks: ['jasmine','requirejs'],
files: [
'node_modules/requirejs/require.js',
'node_modules/karma-requirejs/lib/adapter.js',
'node_modules/angular/angular.js',
'node_modules/angular-mocks/angular-mocks.js',
'public/app/app.js',
'public/tests/spec.js'
],
exclude: [
],
plugins: [
'karma-requirejs',
'karma-chrome-launcher',
'karma-jasmine'
],
preprocessors: {
},
reporters: ['progress'],
port: 9876,
colors: true,
logLevel: config.LOG_INFO,
autoWatch: true,
browsers: ['Chrome'],
singleRun: false,
concurrency: Infinity
})
}
我已经配置了上面的requirejs并且现在得到以下错误： 错误：
Uncaught Error: Mismatched anonymous define() module: function (angular, appModule) {
'use strict';
return appModule.controller('MainCtrl', ['$http', '$q', 'appService', '$stateParams', function($http, $q, $stateParams, appService){
$scope.titleofapp = function(){
$scope.title = 'My Test App !';}
}]);
}

答案 0 :(得分：0)
以下是我编辑的karma.conf.js文件，可以使用RequireJS进行运行。样式为//的评论 - 大多数（除了尾随时）我注释掉的内容，并设置为/* */ - 是关于特定行存在或不存在的目的的真实评论。我希望所有评论都有助于理解正在发生的事情。
module.exports = function(config) {
config.set({
basePath: '',
frameworks: ['jasmine','requirejs'],
files: [
/* not needed because you've told to use requirejs higher in frameworks */
// 'node_modules/requirejs/require.js',
/* i assume this one in no need in your case but could be yes */
// 'node_modules/karma-requirejs/lib/adapter.js',
/* as far as i understand angular.js is amd loadable so don't load it directly */
// 'node_modules/angular/angular.js',
/* i am not sure about this one and how it should be launched so commented it out for now */
// 'node_modules/angular-mocks/angular-mocks.js',
/* will be loaded by tests*/
// 'public/app/app.js',
/* tests should not be loaded directly eigther */
// 'public/tests/spec.js'
/* now configure karma with what will be servable */
{pattern: 'node_modules/**/*.js', included: false}, // all stuff from what npm installed
{pattern: 'src/**/*.js', included: false}, // your source filed
{pattern: 'tests/**/*Test.js', included: false}, // your tests or specs
/* this is the only file to be loaded directly */
'tests/test-main.js' // karma will load this file and it will do all the stuff
],
exclude: [
],
/* karma will load all sibling npm modules with name karma-* so these lines not needed i believe */
// plugins: [
// 'karma-requirejs',
// 'karma-chrome-launcher',
// 'karma-jasmine'
// ],
preprocessors: {
},
reporters: ['progress'],
port: 9876,
colors: true,
logLevel: config.LOG_INFO,
autoWatch: true,
browsers: ['Chrome'],
singleRun: false,
concurrency: Infinity
})
}
然后我在这里为main-test.js文件制作了示例代码。
var allTestFiles = [];
var TEST_REGEXP = /base\/tests\/.*(spec|test)\.js$/i;
// Get a list of all the test files to include
/* as far as i remember window.__karma__.files contains array of all servable files */
Object.keys(window.__karma__.files).forEach(function (file) {
//console.log('original path', file);
if (TEST_REGEXP.test(file)) {
/* below i commented out file path modification suggested at http://karma-runner.github.io/1.0/plus/requirejs.html
* personally i never needed that. Your case might be different so you can play around with this part
*/
var normalizedTestModule = file;//'/base/' + file.replace(/^\/base\/|\.js$/g, '')
//console.log('normalized path', normalizedTestModule);
allTestFiles.push(normalizedTestModule);
}
});
//console.log(allTestFiles); // list all test filed that will be run
/* now confifure requirejs so it could do the job
* for more details please visit http://requirejs.org/docs/api.html#config
*/
require.config({
// Karma serves files under /base, which is the basePath from your config file
/* i prefer this to be default */
baseUrl: '/base/src',
paths: {
/* could be this to do stuff like
* define(['node_modules/cool-module/module.js], function(Module){
*
* });
*/
node_modules: '/base/node_modules',
/* below is just examples that what it could be if you needed those */
// jquery: '/base/node_modules/jquery/dist/jquery',
// underscore: '/base/node_modules/underscore/underscore',
// backbone: '/base/node_modules/backbone/backbone',
// text: '/base/node_modules/requirejs-text/text',
// templates: '/base/src/templates'
},
/* Dynamically load all test files
* An array of dependencies to load. Useful when require is defined as a
* config object before require.js is loaded, and you want to specify
* dependencies to load as soon as require() is defined. Using deps
* is just like doing a require([]) call, but done as soon as the loader
* has processed the configuration. It does not block any other require()

* (http://requirejs.org/docs/api.html#config-deps)
*/
deps: allTestFiles,
/* A function to execute after deps have been loaded. Useful when require
* is defined as a config object before require.js is loaded, and you want
* to specify a function to require after the configuration's deps array
* has been loaded.

* Could be as simple as
* callback: window.__karma__.start
* but i do it via additional wrapper so i can require something specific

*/
callback: startTestWithJasmineJquery
});
function startTestWithJasmineJquery(){
require(['node_modules/jasmine-jquery/lib/jasmine-jquery'], function(){
/* now jasmine-jquery is loaded and its features are available
* so we can window.__karma__.start -- it will actually run tests
*/
window.__karma__.start();
});
}
请注意，所有配置选项都假设文件夹和一些特定文件结构为：
node_modules/
src/
tests/
test-main.js
karma-conf.js
请再次注意，这是我提供的非常基本的配置，可能有一些与angular相关的特定内容或您的项目逻辑和需求，因此可能会有一些（或许多）更改要做。
