In the courses I’m taking we were given a .travis.yml and a makefile to help us automate our project deployment. By default even thought the makefile would notice missing files, the TravisCi testing would pass. So I ended up modifying the makefile to have it fail and force the TravisCI announce the broken build. I also added a new step which on an succesful deployment would automatically merge the Dev and Master branches.

check:
	@for i in $(FILES);                                         \
        do                                                          \
        if [ -e $$i ]; then echo "$$i found" ; else touch .failed && echo "$$i NOT FOUND" ; fi \
        done ; \
        if [ -e .failed ]; then exit 1; else echo "Found all"; fi

Make push merges the dev and master branches, this will be invoked after the make check command in the .travis.yml

push:
ifeq ($(TRAVIS_BRANCH),dev)
	git config --global user.email "marek.bejda@gmail.com"
	git config --global user.name "Marek5050"
	git remote set-branches --add origin master
	git fetch
	git reset --hard
	git checkout master --force 
	git merge --no-ff --no-edit dev
	git push origin master
endif

    - make collatz-tests
