 React Router Testing With Jest
 ====================
-Testing has become much easier since React Router version 1.x. For Testing prior React Router versions, see   [Old testing docs](https://github.com/rackt/react-router/blob/57543eb41ce45b994a29792d77c86cc10b51eac9/docs/guides/testing.md)

 Updating from testing setup from React-Router 0.x to 1.x
 ----------------------------------------------
 Firstly, ensure you are using at least the following versions of each package.
-- "react": "^0.14.0"
-- "react-dom": "^0.14.0"
-- "react-router": "^1.0.0"
-- "react-addons-test-utils": "^0.14.0"
-- "jest-cli": "^0.5.10"
-- "babel-jest": "^5.3.0"

+- `"react-router": "^1.0.0"`
+- `"react-addons-test-utils": "^0.14.0"`
+- `"jest-cli": "^0.5.10"`
+- `"babel-jest": "^5.3.0"`
 
 Also, make sure you are using node 4.x
 
 In prior setups, react-tools was needed. This is not longer the case. You will need to remove it from your package.json and environment.
 
-```
+```json
 "react-tools": "~0.13.3",
 ```
 
 Lastly, anywhere you have the following, needs to be replaced with this:
 
-```
-var React              = require('react/addons');
-var TestUtils          = React.addons.TestUtils;
+```js
+var React = require('react/addons');
+var TestUtils = React.addons.TestUtils;
 ```
 
 with this:
 
-```
-var TestUtils          = require('react-addons-test-utils');
-var ReactDOM           = require('react-dom');
-var React              = require('react');
+```js
+var TestUtils  = require('react-addons-test-utils');
+var ReactDOM = require('react-dom');
+var React = require('react');
 ```
 
 Make sure you do an npm clean, install, etc. and make sure you add react-addons-test-utils and react-dom to your unmocked paths.
