The development group behind the Laravel framework have introduced a new tool that aims to make it easier to report bugs with the framework (not the applications built with them): Laravel Liferaft.
To encourage active collaboration, Laravel currently only accepts pull requests, not bug reports. "Bug reports" may be sent in the form of a pull request containing a failing unit test. [...] A failing unit test or sandbox application provides the development team "proof" that the bug exists, and, after the development team addresses the bug, serves as a reliable indicator that the bug remains fixed.
Following along with this method, Liferaft provides a simple way to download a clean copy of the framework, make the needed changes for the pull request and automatically submit it via GitHub back to the project for handling. In this video on Laracasts Taylor Otwell walks you through a simple example of using it to submit an issue back (and what happens behind the scenes).
