#9883: resolve path to temporary directory to ensure that 'assert_equal' tests also work when $TMPDIR is a symlink
If `$TMPDIR` is a symlink (e.g. `TMPDIR=/local` with `/local` -> `/tmp`), one of the tests fails with the error below due to a hard string comparison of paths using `assert_equals` (see below)
this patch fixes the problem by resolving the path returned by `tempfile.mkdtemp()`
