Creating a Test Site

I’ll soon be installing WP and will want to set up a test site on my server to get things half way decent before I open it up to the world. Eventually I’ll want it to my root but for the test I’ll put it in /test. Are there things I should be aware of at the start to make the final move easier? Is the best way to move it here?
