Running a Pre-Release Test
Prereleases for Indigo and all subsequent distributions are done with Docker containers. This allows you to run the prerelease locally, but without complicated setup or with fear of your system being changed or affecting the prerelease test.
Setup your computer for prerelease test (needed only one time)
To run a prerelease, first setup your system to run prereleases by following the instructions here:
Running prerelease test

For more in depth, see regression_tests#Running_prerelease_test
If the prerelease fails you can check the troubleshooting section on this page:
Note: Pre-releases are only supported for maintained ROS distributions.
