Chaivariables不是由Karma / Grunt加载的
我不能让chai在业力/咕噜声中承诺。
运行grunt test或karma test/karma.conf.js时，出现以下错误：
PhantomJS 1.9.8 (Mac OS X 0.0.0) ERROR ReferenceError: Can't find variable: chai at /Users/isaac/Sites/ChessGame/node_modules/chai-as-promised/lib/chai-as-promised.js:19
这看起来和这个问题类似，但是我正在承担起这个问题，而不是sin-cha。的。 我已经validation了node_modules/chai/chai.js存在。
这是我的package.json文件：
{ "name": "chessgame", "private": true, "devDependencies": { "angular-mocks": "^1.4.3", "chai": "^3.2.0", "chai-as-promised": "^5.1.0", "chai-things": "^0.2.0", "grunt": "^0.4.5", "grunt-angular-templates": "^0.5.7", "grunt-autoprefixer": "^2.0.0", "grunt-concurrent": "^1.0.0", "grunt-contrib-clean": "^0.6.0", "grunt-contrib-compass": "^1.0.0", "grunt-contrib-concat": "^0.5.0", "grunt-contrib-connect": "^0.9.0", "grunt-contrib-copy": "^0.7.0", "grunt-contrib-cssmin": "^0.12.0", "grunt-contrib-htmlmin": "^0.4.0", "grunt-contrib-imagemin": "^0.9.2", "grunt-contrib-jshint": "^0.11.0", "grunt-contrib-uglify": "^0.7.0", "grunt-contrib-watch": "^0.6.1", "grunt-filerev": "^2.1.2", "grunt-google-cdn": "^0.4.3", "grunt-karma": "*", "grunt-mocha": "^0.4.13", "grunt-newer": "^1.1.0", "grunt-ng-annotate": "^0.9.2", "grunt-svgmin": "^2.0.0", "grunt-usemin": "^3.0.0", "grunt-wiredep": "^2.0.0", "jit-grunt": "^0.9.1", "jshint-stylish": "^1.0.0", "karma-browserify": "^4.2.1", "karma-chai": "^0.1.0", "karma-chai-as-promised": "^0.1.2", "karma-chai-things": "^0.1.4", "karma-coverage": "^0.4.2", "karma-jasmine": "*", "karma-mocha": "^0.2.0", "karma-mocha-reporter": "^1.0.3", "karma-phantomjs-launcher": "*", "karma-requirejs": "^0.2.2", "karma-sinon": "^1.0.4", "karma-sinon-chai": "^1.0.0", "mocha": "^2.2.5", "mockfirebase": "^0.11.0", "requirejs": "^2.1.19", "sinon": "^1.15.4", "sinon-chai": "^2.8.0", "time-grunt": "^1.0.0" }, "engines": { "node": ">=0.10.0" }, "scripts": { "test": "grunt test" } }
和test/karma.conf.js文件：
module.exports = function(config) { 'use strict'; config.set({ autoWatch: true, basePath: '../', frameworks: [ "mocha", "chai", "sinon-chai", "chai-as-promised" ], files: [ // bower:js 'bower_components/jquery/dist/jquery.js', 'bower_components/angular/angular.js', 'bower_components/bootstrap-sass-official/assets/javascripts/bootstrap.js', 'bower_components/angular-animate/angular-animate.js', 'bower_components/angular-cookies/angular-cookies.js', 'bower_components/angular-messages/angular-messages.js', 'bower_components/angular-resource/angular-resource.js', 'bower_components/angular-route/angular-route.js', 'bower_components/angular-sanitize/angular-sanitize.js', 'bower_components/angular-touch/angular-touch.js', 'bower_components/firebase/firebase.js', 'bower_components/angularfire/dist/angularfire.js', 'bower_components/angular-mocks/angular-mocks.js', 'bower_components/mocha/mocha.js', 'bower_components/chai/chai.js', 'bower_components/mockfirebase/browser/mockfirebase.js', // endbower 'node_modules/sinon/pkg/sinon.js', 'node_modules/chai/chai.js', 'node_modules/sinon-chai/lib/sinon-chai.js', "app/scripts/**/*.js", "test/mock/**/*.js", "test/spec/**/*.js" ], exclude: [ ], port: 8080, browsers: [ "PhantomJS" ], reporters: ['mocha','coverage'], // preprocessors: { 'app/scripts/controllers/*.js': ['coverage'], 'app/scripts/directives/*.js': ['coverage'], 'app/scripts/app.js': ['coverage'] }, coverageReporter: { type : 'text', dir: 'test-results/coverage/' }, singleRun: false, colors: true, logLevel: config.LOG_INFO, }); };
不幸的是，这是Karma的一个怪癖。 frameworks关键字必须是相反的顺序，所以你必须在加载chai之前加载每个chai插件。 现在你有
frameworks: [ "mocha", "chai", "sinon-chai", "chai-as-promised" ],
如果你改变
frameworks: [ "mocha", "sinon-chai", "chai-as-promised", "chai" ],
那么一切都应该运作良好！ 一些业力插件logging了这一点 ，虽然它肯定会更加突出
