New submission from Michael Yang <yangofz...@gmail.com>:
I want to use the included test.regrtest (located in
$pythondir/lib/python[ver]/test) to regression test some of my own
scripts located in directory myDir. The script has some nice
configurability features to skip some tests based on machine
configurations, etc. that a vanilla unittest suite doesn't include
automatically. However, it seems that the script regrtest.py has an
error following the __import__ line.
Here's my setup:
/sample.py
/myDir
/__init__.py
/test_file1.py
/test_file2.py
/...
in sample.py:
{{{
#!python
#!/usr/bin/env python
import test.regrtest as rt
rt.main(tests = ['myDir.test_file1','myDir.test_file2'], \
quiet = False, verbose = True)
}}}
running sample.py yields:
{{{
#!sh
myDir.test_file1
myDir.test_file1 skipped -- No module named myDir.test_file1
myDir.test_file2
myDir.test_file2 skipped -- No module named myDir.test_file2
2 tests skipped:
myDir.test_file1 myDir.test_file2
2 skips unexpected on win32:
myDir.test_file1 myDir.test_file2
}}}
This is due to the code snippet in regrtest.py around line 554:
{{{
#!python
...
if test.startswith('test.'):
abstest = test
else:
# Always import it from the test package
abstest = 'test.' + test
the_package = __import__(abstest, globals(), locals(), [])
the_module = getattr(the_package, test)
...
}}}
should be changed to:
{{{
#!python
...
if test.startswith('test.'):
abstest = test
modName = test[len('test.'):]
else:
# Always import it from the test package
abstest = 'test.' + test
modName = test
the_package = __import__(abstest, globals(), locals(), [])
the_module = getattr(the_package, modName)
...
}}}
This way, the the_module will correctly find the module name in
'the_package'.
A further recommendation: the main() module should be able to work with
test directories with name other than 'test.*'. Otherwise, users
wishing to use the main() on other directories will have to name them
'test.' Depending on the user's directory's position in sys.path
(before or after $pythondir/lib/python[ver]), regrtest.main() will
either fail due to the 'from test import ...' statements being shadowed
by the user's 'test' directory or the user's 'test' directory being
shadowed by the standard library's.
