Git Commit Tester
The git commit tester is an autotester that automatically compiles and runs the dmd, druntime, and phobos unittests on all officially-supported platforms. The autotester also automatically runs when a pull request is submitted on GitHub and found on the Pulls page. The test results are incrementally posted to the pull request page on GitHub.
Generally, pull requests will not be accepted if they fail one or more autotests.
