One of the issues in developing an Emacs Lisp package was configuring a test suite. You could set up a Travis CI for an Emacs Lisp project using Cask, but it was not very elegant. You had to specify dependencies both in the library header and the Cask file, which was redundant. Recently, a utility named EMake has been released. I developed a solution for running package lint before, but EMake can run package-lint, byte-compile, and ERT/buttercup tests and does not depend on Cask.
