Angular 运行 Karma 测试时未加载(遵循教程)
Angular not loading when running Karma tests (following a tutorial)
我正在尝试了解如何在编写 Angular 应用程序时采用测试驱动开发方法;我一直在关注 Introduction to Angular Test Driven Development 教程。
在我编写任何测试之前,我在第一个障碍上失败了。
当我从 tutorial/
目录 运行 karma start
时,出现错误:
Karma v 6.3.2 - connected; test: karma_error An error was thrown in afterAll Uncaught ReferenceError: angular is not defined ReferenceError: angular is not defined at http://localhost:9876/base/app/app.js
如何加载 Angular?
我目前的理解是 angular
应该自动加载,因为 karma.conf.js
中的 files: []
行并且 app.js
应该可以访问它。目前,我的 app.js
正在创建一个基本控制器,仅此而已,据我所知,我的代码与本阶段教程中的代码相匹配。该教程有一个 Git Hub repository.
根据教程,我的目录结构如下:
tutorial/
|-app/
|---app.js
|-karma.conf.js
|-node_modules/ [Only listing relevant files]
|---angular/
|------angular.js
|---angular-mocks/
|------angular-mocks.js
|-package.json
|-tests/
|--[empty dir]
这是我的全部app/app.js
:
angular.module('ItemsApp', [])
.controller('MainCtrl', function($scope) {
$scope.title = 'Items App Title'
});
这是我的 karma.conf.js
:
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: [
'app/**.js',
'tests/**.js',
'node_modules/angular/angular.js',
'node_modules/angular-mocks/angular-mocks.js'
],
// list of files / patterns 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: ['Chrome'],
// Continuous Integration mode
// if true, Karma captures browsers, runs the tests and exits
singleRun: false,
// Concurrency level
// how many browser should be started simultaneous
concurrency: Infinity
})
}
当 运行 karma init
.
时,本教程建议您以错误的顺序提供应用程序的路径
由于app/app.js
依赖于node_modules/angular/angular.js
,后者应该先声明。要解决此问题,请更新 karma.conf.js
以声明:
files: [
'node_modules/angular/angular.js',
'node_modules/angular-mocks/angular-mocks.js',
'app/**.js',
'tests/**.js'
],
这是教程示例文件中显示的顺序,但不是我按照 运行 karma init
教程中的说明生成的(在我的系统上)顺序。
