How can I make it so unit tests in Python (using unittest) are run in the order in which they are specified in the file?

The default order is alphabetical. You can put test_<int> before every test to specify the order of execution.

Also you can set unittest.TestLoader.sortTestMethodsUsing = None to eliminate the sort.

Check out Unittest Documentation for more details.

hacky way (run this file in pycharm or other unit test runner)

#!/usr/bin/env python
# -*- coding: UTF-8 -*-
import unittest


def make_suite():
    class Test(unittest.TestCase):
        def test_32(self):
            print "32"
        def test_23(self):
            print "23"

    suite = unittest.TestSuite()
    suite.addTest(Test('test_32'))
    suite.addTest(Test('test_23'))
    return suite

suite = make_suite()

class T(unittest.TestCase):
    counter = 0
    def __call__(self, *args, **kwargs):
        res = suite._tests[T.counter](*args, **kwargs)
        T.counter += 1
        return res

for t in suite._tests:
    name = "{}${}".format(t._testMethodName, t.__class__.__name__)
    setattr(T, name, t)
