Hi Louis, Here are the 2 versions of the test.

gistfile1.js

  // this works as expected
  describe("github test", function() {
    var res;
    res = {};
    before(function(done) {
      chai.request(githubReqObj.url).get('').req(function(req) {
        req.set({
          'Accept': 'application/vnd.github.beta+json',
          'User-Agent': 'A test application for homebrew cask dotfile'
        });
      }).res(function(response) {
        res = response;
        done();
      });
    });
    it("should connect with a 200 status", function() {
      expect(res).to.have.status(200);
    });
  });
