Description: Change dotexport test to use tmpdir to fix race condition
In the upstream package, the dotexport test manually creates and
deletes temporary directories in a way that exposes it to possible
race conditions. This patch corrects that by having it use the pytest
tmpdir constructs, which handle temporary directories safely.
