General Note about CI Services in use for Building Whonix ™
Since all Continuous Integration (CI) services we know of run Ubuntu and Whonix ™ is based on Debian.
Even if a Whonix ™ Ubuntu based build would exist and CI build pass, that would not necessarily mean, that a Debian based build would have passed as well. Therefore the usefulness of the results would be limited anyhow. Nevertheless, compatibility with CI environments is a very useful "stress test" for the build script. It helps early spotting most bugs, which break the build.
Since there are no free CI services supporting mount (device-mapper), there is unfortunately no CI service which could be used for building Whonix ™ Virtual Machine images.
