the issue came up, where is the unit test for trace.py?

test/test_trace.py is actually a test of the line trace facility of sys.settrace (and should have been called test_linetrace or test_settrace). The only trace import Eli could find in Lib/test is the one in regrtest.py for the -T option. Have we missed something?

If you say 'make one', what should be its name? Can the existing file be renamed (I gather this can be a bit of a problem)?

I'd like to ask pydev another question on this issue. When thinking about adding unit tests for trace.py, I quickly realized it's not a usual module. Most of its output is either tracing reports to stdout, or even worse, to special files named <modname>.cover

stdout output can be captured, but what about the .cover files? Can a Python unit test create temporary files in tmp/ (or somewhere else) as part of its testing, or is this forbidden?
