One way we can achieve this is by using git update-index with the --assume-unchanged flag.

After following this guide, you will have a Vagrant box equiped with Selenium server including all tools needed to execute web tests on a headless VM. No more fighting with configurations. Once setup, you can share the box with your team and if anything goes wrong you can easily replicate this box. Running headless stops Selenium from taking over your machine by poping up browsers so you can focus on other tasks while your tests run in the background.

To use Vagrant on windows 7, first download and install the following on your host machine:

Some common types of web tests you could start with are content, links, function and dynamic element tests. The easiest would be content testing and hardest would be functional testing. Which type of testing to perform first could vary depending on a variety of factors including project budget, user expectation and update frequency.

Selenium WebDriver is a tool for automating web testing. It automates testing by making direct calls to the browser allowing you to compare expected against actual results. It makes direct calls to the browser using javascript.
