我正在尝试使用单元测试来设置Angular2项目。 我正在使用本手册：http://twofuckingdevelopers.com/2016/01/testing-angular-2-with-karma-and-jasmine/ 它显然已经过时了，因为现在默认的Angular2 npm包是@angular / *
所述示例不起作用，因为angular2包不同。 所以我将所有内容重新映射到@angular包。
我的package.json包含以下依赖项：
"dependencies": {
"@angular/common": "^2.0.0-rc.5",
"@angular/compiler": "^2.0.0-rc.5",
"@angular/core": "^2.0.0-rc.5",
"@angular/http": "^2.0.0-rc.5",
"@angular/platform-browser": "^2.0.0-rc.5",
"@angular/platform-browser-dynamic": "^2.0.0-rc.5",
"@angular/router": "^3.0.0-rc.1",
"@angular/router-deprecated": "^2.0.0-rc.2",
"@angular/upgrade": "^2.0.0-rc.5",
"es6-promise": "^3.2.1",
"es6-shim": "^0.35.1",
"reflect-metadata": "^0.1.2",
"rxjs": "5.0.0-beta.6",
"zone.js": "^0.6.17"
},
"devDependencies": {
"@angular/testing": "^0.0.0-0",
"concurrently": "^2.0.0",
"eslint": "^3.3.1",
"eslint-config-google": "^0.6.0",
"eslint-config-standard": "^6.0.0",
"eslint-plugin-promise": "^2.0.1",
"eslint-plugin-standard": "^2.0.0",
"jasmine-core": "2.4.1",
"karma": "^1.2.0",
"karma-chrome-launcher": "^2.0.0",
"karma-coverage": "^1.1.1",
"karma-jasmine": "^1.0.2",
"lite-server": "^2.2.0",
"remap-istanbul": "^0.6.4",
"typescript": "^1.8.10",
"typings": "^1.0.4"
}
我删除了所有node_packages文件夹，从干净的平板开始。
运行＆＃34; npm install＆＃34;时，我看到以下输出：
$ npm install

我应该怎样做才能让它发挥作用？ 或者您可以建议涵盖单元测试的教程，该教程适用于最新的Angular2版本吗？

我相信你应该在angular.io网站上遵循这个指南，它告诉你关于jasmine-core以及如何用npm安装它。 使用该库，您应该能够进行您尝试设置的测试。

我发现使用karma-webpack运行测试更容易。
请参阅此提交，了解我如何为angular2 lib https://github.com/tb/ng2-api/commit/ef73d95b516579d7aaa9b8b55c906d140abcf3ab

使用以下命令
更新npmnpm install npm -g
答案 3 :(得分：0)
Angular2 CLI解决了一个问题： https://cli.angular.io
它完成了所有测试。
