-Mutations are very straightforward to test, because they are just functions that completely rely on their arguments. Actions can be a bit more tricky because they may call out to external APIs. When testing actions, we usually need to do some level of mocking - for example, we can abstract the API calls into a service and mock that service inside our tests. In order to easily mock dependencies, we can use Webpack and [inject-loader](https://github.com/plasticine/inject-loader) to bundle our test files.
+Mutations 很容易测试，因为它仅仅是一个带参数的函数。相反测试 Actions 就比较难，因为 actions 会调用其它的一些 APIs. 测试 actions 的时候我们需要做一定的 mocking —— 比如说把 API 调用抽象成一个 service，然后测试的时候用另一个 mock 的 service. 为了方便地 mock，我们可以使用 Webpack 和 [inject-loader](https://github.com/plasticine/inject-loader) 打包测试文件。
 
 If your mutations and actions are written properly, the tests should have no direct dependency on Browser APIs after proper mocking. Thus you can simply bundle the tests with Webpack and run it directly in Node. Alternatively, you can use `mocha-loader` or Karma + `karma-webpack` to run the tests in real browsers.
