Although regrtest supposedly has a coverage option (I could not get it
to work ;-), the devguide recommends cloning coveragepy (with unix
instructions). I wrote the following cover.bat file for using it on windows.
@echo off
rem Usage: cover fileName [test_ suffix] # proper case required
setlocal
set py=py33\pcbuild\python_d
set src=idlelib.%1
if "%2" EQU "" set tst=py33/Lib/idlelib/%1.py
if "%2" NEQ "" set tst=py33/Lib/idlelib/idle_test/test_%2.py
%py% coveragepy run --pylib --source=%src% %tst%
%py% coveragepy report --show-missing
%py% coveragepy html
htmlcov\py33_Lib_idlelib_%1.html
The last line opens the report in the default browser. In includes a
copy of the target file with missed lines highlighted in pink. Very
nice, and mush better than regrtest would do even if it worked.
I used 'cover FormatParagraph' to identify the lines missed by Phil's
last patch for test_formatparagraph and added tests to boost covereage
to 100% (the 'if __name__' block in FormatParagraph.py prevents it as
being recognized as 100%, but it is)
