Seemed pretty simple, basically, I created a sub domain of "test" which in turn created a folder structure like "/home/test/" and then I installed wordpress to it and that was it. the current site is stored at www.juliegracestudio.com
and the test site is stored at test.juliegracestudio.com/test/ which is technically www.juliegracestudio.com/home/test/
but somehow it auto redirects or something. so what I have is basically a copy of the whole site wordpress and all in a child folder.
