In this case, a JavaScript front-end that had no unit tests previously. I also wasn't able to get NPM through the firewall, so I used Jasmine standalone and kept its files and copies of our third-party framework files in a "Frameworks" folder within a separate "Test" folder

The pushback I received was that keeping the framework code in Source Control would result in it being caught in the JS build/minification script, as well as my spec files. The individual that pushed back was also concerned about JS exceptions since we were up against a release, which speaks to a need for training about how unit test files work. Ultimately I .gitignored the framework folder but wouldn't budge on leaving the test files in, since .gitignoring unit tests defeats the purpose. Then I learned that the build script wouldn't grab those files anyway. :)
