ValueError: need more than 2 values to unpack

[kahmed]

When running nosetests i get error:

test_many_errors.test_value_two ... SKIP: (<type
'exceptions.ValueError'>, ValueError(), <traceback object at
0x1218cd8>)
test_many_errors.test_good_one ... ok
test_many_errors.test_good_two ... ok

--------------------- >> end captured stdout << ----------------------

Here is the code snippet:

def get_error_count(lookup, index):
if index in lookup:
ename = lookup[index]
return _errormap[ename]

self.printErrorList('ERROR', self.errors,
lambda i: get_error_count(self._error_lookup, i))
self.printErrorList('FAIL', self.failures,
lambda i: get_error_count(self._failure_lookup,
i))

def printErrorList(self, flavor, errors, get_error_count):
i = 0
for test, err, capt in errors:
self.stream.writeln(self.separator1)
self.stream.writeln("%s: %s" %
(flavor,self.getDescription(test)))
self.stream.writeln(self.separator2)
self.stream.writeln("%s" % err)
#count = get_error_count(i)
count = get_error_count(i)
if count > 1:
self.stream.writeln(self.separator2)
self.stream.writeln("+ %s more" % (count-1))
self.stream.writeln(self.separator2)
if capt is not None and len(capt):
self.stream.writeln(ln('>> begin captured stdout <<'))
self.stream.writeln(capt)
self.stream.writeln(ln('>> end captured stdout <<'))
i += 1


How do i resolve this ?

Thanks,

Somewhere in "errors" is a value that is not of length 3.

Try this to find out what's wrong:

for errorentry in errors :
try :
(test, err, capt) = errorentry # try to unpack
except ValueError as message : # unpack failed
raise(ValueError("%s: bogus entry in 'errors': %s" %
(message, repr(errorentry))))
...
