Alternatively you can write your own test loader:
$ cat ordered_unittest2.py
import unittest
class Test(unittest.TestCase):
def test_gamma(self):
pass
def test_beta(self):
pass
def test_alpha(self):
pass
class Loader(unittest.TestLoader):
def getTestCaseNames(self, testCaseClass):
"""Return a sequence of method names found within testCaseClass
sorted by co_firstlineno.
"""
def first_lineno(name):
method = getattr(testCaseClass, name)
return method.im_func.__code__.co_firstlineno
function_names = super(Loader, self).getTestCaseNames(testCaseClass)
function_names.sort(key=first_lineno)
return function_names
if __name__ == "__main__":
unittest.main(testLoader=Loader())
$ python2.7 ordered_unittest2.py -v
test_gamma (__main__.Test) ... ok
test_beta (__main__.Test) ... ok
test_alpha (__main__.Test) ... ok
----------------------------------------------------------------------
Ran 3 tests in 0.001s
OK
