+Selenium example
+================
+
+[![Build Status](https://travis-ci.org/leutloff/selenium-example.png?branch=master)](https://travis-ci.org/leutloff/selenium-example)
+[![Dependencies](https://gemnasium.com/leutloff/selenium-example.png)](https://gemnasium.com/leutloff/selenium-example)
+
+
+This project provides two complete simple examples written in JavaScript ([node.js](http://nodejs.org/)) 
+using the Web Application Test Framework [Selenium](http://docs.seleniumhq.org/projects/webdriver/). 
+A complete description is provided from the initial author [Nathan Oehlman](https://github.com/nathanoehlman) at 
+[http://unexpectedliteral.com/2012/05/09/automated-functional-testing-with-javascript-using-mocha-and-selenium-part-2/](http://unexpectedliteral.com/2012/05/09/automated-functional-testing-with-javascript-using-mocha-and-selenium-part-2/).
+
+The used test runner is [Mocha](http://visionmedia.github.io/mocha/). 
+Two styles of result checking TDD and BDD are shown. Both styles are provided by the [Chai](http://chaijs.com/) Library. 
+
+
+Install the prerequisites
+========================
+
+For locally running tests:
+
+- Check that node.js and npm are installed, e.g. execute `node --version` and `npm --version`.
+  If this is not the case install them, e.g.
+        sudo apt-get install nodejs -y
+        curl https://npmjs.org/install.sh > install-npm.sh && sudo sh install-npm.sh
+- Install the chromedriver for your system, e.g. for Linux
+        curl https://chromedriver.storage.googleapis.com/2.21/chromedriver_linux64.zip > chromedriver_linux64.zip 
+        unzip chromedriver_linux64.zip 
+        sudo mv chromedriver /usr/local/bin
+        sudo chmod +rx /usr/local/bin/chromedriver
+- Install Mocha globally:
+        sudo npm install -g mocha
+- To install the other Javascript related parts just execute 
+        sudo npm install
+- Then exceute
+        make 
+  or install and launch selenium server, e.g.
+        curl -O https://selenium-release.storage.googleapis.com/2.50/selenium-server-standalone-2.50.1.jar
+        java -jar selenium-server-standalone-2.50.1.jar &
+  and start the tests with npm
+        npm test
+
+
+Executing the examples
+======================
+
+Just call `mocha`. Mocha will then execute all the scripts in the directory named test.
+
+
+Troubleshooting
+===============
+
+1) The test 'simple internet' fails and there is this message shown:
+   Only local connections are allowed.
+
+Ensure that the chromedriver is matching the selenium-server, e.g. try 
+upgrade both to the latest releases.
