With all the Vim forks and reinventions of Vim, I thought readers might find it interesting to learn about vim-ci, created by the vim-jp community.
This repository includes a fork of Vim as a submodule and includes a build script so a continuous integration server like Travis can easily handle the output. The build script triggers
make && make test so it's easy to run the tests.
I found this through a thread on vim dev where Marslo Jiao was asking about how to adapt Vim to help maintain a Windows Vim build.
