**Custom prefix for Python unit test methods** (doing BDD in Python and wanted proper prefixes instead of the default 'test' prefix, and pytest had a bug: https://bitbucket.org/hpk42/pytest/issue/284/python_classes-and-python_functions)

gistfile1.py

import unittest
unittest.TestLoader.testMethodPrefix = 'should'
from unittest import TestCase as Specification


class MyClass(Specification):
  
    def should_do_something():
        """This method with the 'should' prefix will be picked up by test runners"""
