In reviewing http://bugs.python.org/issue9282 the issue came up, where is the unit test for trace.py?
test/testtrace.py is actually a test of the line trace facility of sys.settrace (and should have been called testlinetrace or testsettrace). 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 .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?
