gulp-jasmine 窗口未定义错误

Question

我正在使用 gulp / gulp-jasmine / angular 来运行我的单元测试。但是，我在运行 Gulp 目标时遇到以下错误：

C:\Projects\website2>gulp test
[01:53:10] Using gulpfile C:\Projects\website2\gulpfile.js
[01:53:10] Starting 'test'...
[01:53:11] Version: webpack 1.4.13
         Asset     Size  Chunks             Chunk Names
test.bundle.js  1051728       0  [emitted]  test
F

Failures:
1) Exception loading: C:\Projects\website2\scripts\dist\test.bundle.js Error
1.1) ReferenceError: window is not defined

1 spec, 1 failure
Finished in 0.015 seconds
[01:53:11] 'test' errored after 916 ms
[01:53:11] Error in plugin 'gulp-jasmine'
Message:
    Tests failed

我相信 gulp-jasmine 使用 PhantomJS（没有触发浏览器窗口）。有人可以帮我解决我做错的事情吗？是否有我缺少的配置设置？

这是我的 gulpfile.js：

var gulp = require('gulp');
var path = require('path');
var webpack = require('gulp-webpack');
var webpackConfig = require('./webpack.config');
var testWebpackConfig = require('./test.webpack.config');
var jasmine = require('gulp-jasmine');

gulp.task('default', ['build'], function() {

});

gulp.task('build', function() {
    return gulp.src(['scripts/app/**/*.js', '!scripts/app/**/*.tests.js'])
       .pipe(webpack(webpackConfig))
       .pipe(gulp.dest('scripts/dist'));
});

gulp.task('test', function() {
    return gulp.src(['scripts/app/**/*.tests.js'])
       .pipe(webpack(testWebpackConfig))
       .pipe(gulp.dest('scripts/dist'))       
       .pipe(jasmine());
});

gulp-jasmine 通过 Node.js 运行测试，因此不适合客户端测试，请参阅 https://github.com/sindresorhus/gulp-jasmine/issues/46

对于客户端测试，如果您想使用 Jasmine（而不是 Karma 或并行），您可以编写一个 SpecRunner.html 文件（名称无关紧要）并在浏览器中运行：

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <title>Jasmine Spec Runner</title>

    <!-- You need to specify package 'jasmine-core' in your Node.js package.json -->

    <link rel="shortcut icon" href="node_modules/jasmine-core/images/jasmine_favicon.png">
    <link rel="stylesheet" href="node_modules/jasmine-core/lib/jasmine-core/jasmine.css">

    <script src="node_modules/jasmine-core/lib/jasmine-core/jasmine.js"></script>
    <script src="node_modules/jasmine-core/lib/jasmine-core/jasmine-html.js"></script>
    <script src="node_modules/jasmine-core/lib/jasmine-core/boot.js"></script>

    <!-- Source and Spec dependencies -->
    <script src="node_modules/underscore/underscore.js"></script>
    <script src="node_modules/angular/angular.js"></script>
    <script src="node_modules/angular-mocks/angular-mocks.js"></script>

    <!-- Source files -->
    <script src="app/MySourceCode1.js"></script>
    <script src="app/MySourceCode2.js"></script>

    <!-- Spec files -->
    <script src="test/MySourceCode1.spec.js"></script>
    <script src="test/MySourceCode2.spec.js"></script>
  </head>
  <body>
  </body>
</html>

或者使用gulp-jasmine-browser:

var gulp = require('gulp');
var $ = require('gulp-load-plugins')();

// You need to specify packages 'jasmine-core' and 'gulp-jasmine-browser'
// in your Node.js package.json

gulp.task('jasmine', function() {
  return gulp.src([
    'node_modules/underscore/underscore.js',
    'node_modules/angular/angular.js',
    'node_modules/angular-mocks/angular-mocks.js',

    'app/MySourceCode1.js',
    'app/MySourceCode2.js',
    'test/MySourceCode1.spec.js',
    'test/MySourceCode2.spec.js',
  ])
    .pipe($.jasmineBrowser.specRunner())
    .pipe($.jasmineBrowser.server());
});

或使用Karma :)

我能够以另一种方式解决这个问题，将 PhantomJS 用于无头浏览器，将 karma 用于命令行测试运行器，将 jasmine 用于测试框架，并将 gulp 用于任务运行器。

karma.conf.js

module.exports = function(config) {
    config.set({
        basePath: './',

        files: [
            'node_modules/angular/angular.js',
            'node_modules/angular-mocks/angular-mocks.js',
            'index-controller.js',
            'index-controller.tests.js'
        ],

        exclude: [
        ],

        autoWatch: true,

        frameworks: ['jasmine'],

        browsers: ['PhantomJS'],

        plugins: [
            'karma-jasmine',
            'karma-junit-reporter',
            'karma-chrome-launcher',
            'karma-firefox-launcher',
            'karma-phantomjs-launcher'
        ],

        junitReporter: {
            outputFile: 'unit.xml',
            suite: 'unit'
        }

    })
}

安装必要的 npm 模块：

npm install angular
npm install angular-mocks
npm install -g gulp
npm install gulp
npm install karma
npm install -g karma-cli
npm install karma-jasmine
npm install karma-junit-reporter
npm install karma-chrome-launcher
npm install karma-firefox-launcher
npm install karma-phantomjs-launcher
npm install phantomjs

更新您的 gulpfile.js 并提供两个任务：运行单元测试一次的默认任务，监视文件系统并在任何文件更改时运行测试的 TDD 任务：

gulpfile.js

var gulp = require('gulp');
var karma = require('karma').server;
gulp.task('default', function(done) {
  karma.start({      
    configFile: __dirname + '/karma.conf.js', 
        singleRun: true 
   }, done); 

});

gulp.task('tdd', function (done) { 
   karma.start({ 
     configFile: __dirname + '/karma.conf.js' 
   }, done); 
}); 

触发：

gulp default
gulp tdd

为了完整起见，这是我的索引控制器和相关测试：

index-controller.js

var app = angular.module('app', []);
app.controller('ctrl', function($scope) { 
    $scope.name = 'mickey mouse';
});

index-controller.tests.js

describe('index-controller', function() {
    beforeEach(module('app'));
    var $controller;

    beforeEach(inject(function(_$controller_){
        // The injector unwraps the underscores (_) from around the 
        // parameter names when matching
        $controller = _$controller_;
    }));

    describe('$scope.name', function() {
        it('should be mickey mouse', function() {
            var $scope = {};
            var controller = $controller('ctrl', { $scope: $scope });

            expect($scope.name).toEqual('mickey mouse');
        });

  });
});
