没有“beforeEach”的测试通过，但注入失败

Question

我创建了一个网络应用程序并尝试使用 Karma & Jasmine 测试我的 JavaScript。我的测试如下所示：

'use strict';

describe('Controller: LoginController', function () {

   // load the controller's module
   beforeEach(module('login'));

   var MainCtrl,
       scope;

   // Initialize the controller and a mock scope
   beforeEach(inject(function ($controller, $rootScope) {
       scope = $rootScope.$new();
       MainCtrl = $controller('LoginController', {
           $scope: scope
       });
   }));

   it('true is of course true', function () {
       expect(true).toBe(true);
   });
});

我将以下内容放在我的 karma.conf.js 文件中：

module.exports = function(config) {
config.set({

// base path that will be used to resolve all patterns (eg. files, exclude)
basePath: '',


// frameworks to use
// available frameworks: https://npmjs.org/browse/keyword/karma-adapter
frameworks: ['jasmine'],


// list of files / patterns to load in the browser
files: [
  './node_modules/angular/angular.js',
  './node_modules/angular-mocks/angular-mocks.js',
  './node_modules/angular-route/angular-route.js',
  './app.js',
  './login/LoginController.js',
  './tests/*.js',
],


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


// preprocess matching files before serving them to the browser
// available preprocessors: https://npmjs.org/browse/keyword/karma-preprocessor
preprocessors: {
},


// test results reporter to use
// possible values: 'dots', 'progress'
// available reporters: https://npmjs.org/browse/keyword/karma-reporter
reporters: ['progress'],


// web server port
port: 9876,


// enable / disable colors in the output (reporters and logs)
colors: true,


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


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


// start these browsers
// available browser launchers: https://npmjs.org/browse/keyword/karma-launcher
browsers: ['Safari'],

plugins: [
  'karma-jasmine',
    'karma-safari-launcher'
],


// Continuous Integration mode
// if true, Karma captures browsers, runs the tests and exits
singleRun: true,

// Concurrency level
// how many browser should be started simultaneous
concurrency: Infinity
})
}

当我在没有从 //load 控制器模块到“it”案例的情况下运行我的测试时，它通过了。但是有了它，我的终端中出现错误和以下内容： node_modules/angular/angular.js:68:32 node_modules/angular/angular.js:4640:30 forEach@node_modules/angular/angular.js:321:24 loadModules@node_modules/angular/angular.js:4601:12 createInjector@node_modules/angular/angular.js:4523:30 workFn@node_modules/angular-mocks/angular-mocks.js:3074:60 loaded@http://localhost:9877/context.js:151:17

我不熟悉 angular、jasmine 和 karma，并试图通过其他问题搜索我的方式，但没有任何效果。有什么想法可以帮助吗？

好吧，我没有看到您告诉 karma 包含您的登录模块所依赖的模块。这可能是当 Angular 尝试在 beforeEach 中初始化您的模块时测试失败的原因。
