Visualization of PHPUnit Development
According to svn.php.net, I committed the first PHPUnit code to cvs.php.net/ on November 27th 2001 and the first release, PHPUnit 0.1, was made on December 1st 2001.
I started using svn.phpunit.de for the development of PHPUnit on June 29th 2006. I did not import any history from CVS into Subversion.
On December 26th 2009, I moved the development of PHPUnit from svn.phpunit.de to GitHub. I imported the history from Subversion into Git. As you can see in the video, moving to GitHub lead to an increased number of contributions to PHPUnit.
