 ## 配置和工具
 
-Anything compatible with a module-based build system will work, but if you're looking for a specific recommendation, try the [Karma](http://karma-runner.github.io) test runner. 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.
+任何兼容基于模块的构建系统都可以正常使用，但如果你需要一个具体的建议，可以使用[Karma](http://karma-runner.github.io)进行自动化测试。它有很多社区版的插件，包括对[Webpack](https://github.com/webpack/karma-webpack)和[Browserify](https://github.com/Nikku/karma-browserify)的支持。更多详细的安装步骤，请参考各项目的安装文档，通过这些Karma配置的例子可以快速帮助你上手（[Webpack](https://github.com/vuejs/vue-loader-example/blob/master/build/karma.conf.js)配置，[Browserify](https://github.com/vuejs/vueify-example/blob/master/karma.conf.js)配置）。

 ## 编写可被测试的组件
 
-A lot of components' render output are primarily determined by the props they receive. In fact, if a component's render output solely depends on its props, it becomes quite straightforward to test, similar to asserting the return value of a pure function with different arguments. Take an contrived example:
