## The PHPUnit Initiative ## __The PHPUnit Initiative__
As part of the PHPUnit initiative __a considerable part of Simpletests will be converted to PHPUnit based browser tests on February 21st 2017__. A backwards compatibility layer has been implemented so that many Simpletests can be converted by just using the new BrowserTestBase base class and moving the test file. There is also a script to automatically convert test files in the conversion issue.
