[Python] Detecting testcases created dynamically while running unittest module

I've faced a problem. In my situation I create testcases dynamically like this

class TestMetrics(unittest.TestCase):
@staticmethod
def generate_test(test: ElementaryTestCase):
def test_instance(self):
...
self.assertLessEqual(...)
...
return test_instance


and then in module's body add another generate_test function to the TestMetrics class

tests_query = prepare_test_query()

for test in tests_query:
formatted_test_name = '_'.join(test.test_name.strip().split())
test_method = TestMetrics.generate_test(test)
test_name = f'test_{formatted_test_name}'

setattr(TestMetrics, test_name, test_method)


It works fine when I start my tests with unittest.main(), but now my goal is to start them as it should be using python3 -m unittest test_modulename, but it obviously sees 0 tests. I want to try to itegrate it with allure then, so that's why I need this opportunity to start tests by default. Is there any solution how to make unittest see generated tests?

Example of what's going on

import unittest

class TestExample(unittest.TestCase):
@staticmethod
def generate_test(*args):
def test_instance(self):
a,b = args
self.assertEqual(a, b)
return test_instance

values = [
(1, 1, 'example'),
(12, 12, 'another_example'),
(0, 5, 'fail_test')
]

for val in values:
test_name = 'test_' + val[-1]
test_method = TestExample.generate_test(*val[:2])
setattr(TestExample, test_name, test_method)

unittest.main()
