If a test fails (or breaks in some way) and the temp-file has been
created, it remains in the `temporary-file-directory' (the test system
uses the standard Emacs make-temp-file mechanism). The file is
referenced in the ert failure backtrace, and may be viewed in Emacs (press `b' on
the failure in ert), although there is usually enough information in the
backtrace / test-case to point to the failure.

Emacs takes care of removing the old tmp files over time.
