-Anything compatible with a module-based build system will work, but if you're looking for a specific recommendation, 使用 [Karma](http://karma-runner.github.io) 进行自动化测试. It has a lot of community plugins, including support for [Webpack](https://github.com/webpack/karma-webpack) and [Browserify](https://github.com/Nikku/karma-browserify). For detailed setup, please refer to each project's respective documentation, though these example Karma configurations for [Webpack](https://github.com/vuejs/vue-loader-example/blob/master/build/karma.conf.js) and [Browserify](https://github.com/vuejs/vueify-example/blob/master/karma.conf.js) may help you get started.
