Selection based testing not working

[andyrichardson]

The main reason I got this package was to run tests independently. This isn't working however as ctrl-alt-m just runs all tests within the file.

  describe("Slot Responses", function(){
    it("respond to friends slot", function(){
      const data = {
        accessToken: user1AccessToken,
        username: user2.username
      };

      return api.getUserAuthenticated(data)
      .then(function(data){
        console.log(data);
      })
    });
  });

Having the cursor on the describe or it line has no effect; nor does highlighting the selection. Is this due to using vanilla javascript rather than coffeescript?
