It's not a standard python file. You are most likely using
framework.py (very much deprecated) and it uses a lot of python
evaluation tricks that are confusing Wing. The line jumps you see are
in fact line numbers in framework.py and associated files, but the
current filename is never set so Wing shows the prompt in the wrong
Use "zopectl test" (test.py) to debug Plone and Zope unittests
instead. Modern PloneTestCase uses test.py layers to load all the
dependencies, and supports Five/zope3 configuration properly. In
fact, if this is on a recent Plone/Zope combo, you will most likely
see strange errors related to not-found users and such if you run
with framework.py still.
To run such tests in Wing, make the following configuration changes:
Under project properties, set the following environment variables:
set /path/to/zope/bin/test.py as the main debug file (right click in
the project file list). Also change test.py's file properties (again
right click). On the debug tab set it's arguments to:
-v --config-file "$INSTANCE_HOME/etc/zope.conf"
These arguments match what 'zopectl test' pass on to test.py. I
usually add to that "-s Products.currentproduct" and "-t currenttest"
to constrain what tests are run. See test.py --help to see what other
options you can use.
Now, whenever you want to run your tests, just hit F5 (start debug)
and adjust the arguments of test.py to narrow down what tests are
run, and debug your tests. Note that during the very first run you'll
need to ignore a handful of uncought expressions first.
Hope this helps,
PS. Note to Wingware: I'd love to see Wing support this as part of
the already present Zope support. Add the environment variables by
default, and add a "Debug current Product tests" option, which runs
test.py with the above arguments plus the -s argument with the
current module path, and a dialog box allowing you to set further
arguments to test.py such as the -t switch. :-)
