Title: Output test files to test directory

Currently `d_do_test` outputs temporary files into the root directory `test`, and if for any reason you decide to stop the tester in the middle of a run you will be left with temporary files, which will show up when you run `git status`.

I've changed it to output the temp files to the temporary directory of the OS.
