Summary: unittest.py, better error message
Initial Comment:
These two methods of the class TestCase are not very good:
def failUnlessEqual(self, first, second, msg=None):
"""Fail if the two objects are unequal as
determined by the '!='
operator.
"""
if first != second:
raise self.failureException, \
(msg or '%s != %s' % (`first`, `second`))
def failIfEqual(self, first, second, msg=None):
"""Fail if the two objects are equal as
determined by the '=='
operator.
"""
if first == second:
raise self.failureException, \
(msg or '%s == %s' % (`first`, `second`))
The first thing is that you should print the difference
of the given values like that:
'<%s> == <%s>' % (`first`, `second`)
The < and > delimits the string and so is is easier to
detect where the string starts and where it ends.
The second thing is that I would really like to see the
two values that are (not) equal even if I provide a
message. Maybe its better to raise the exception like that:
if msg is not None:
msg += ' Expected: <%s>, is: <%s>' %
(first, second)
raise self.failureException, \
(msg or '%s != %s' % (`first`, `second`))
bye Stefan
