We have some internal proxies for all of the Jasmine functions, as well as some other helpers. This code hasn't been touched in more than 5 years, it can lead to confusion and it isn't really necessary since the same can be achieved using Jasmine. These changes remove most of the code and clean up our existing unit tests. PR Close #42177
