Is there a way of running the same python test with different inputs

Question

Is there a way of running the same python test with multiple inputs? Ideally using unittest, but open to other libraries if not.

I'd like to be able to write something along the lines of

@inputs(1,2,3) @inputs(4,5,9) def test_my_test(self, a, b, c): self.assertEqual(a + b, c)

unittest itself doesn't provide something like this, but pytest does, and I've used the ddt module in the past with unittest. — chepner

@chepnerddt provides exactly what I'm looking for. If you add that as an answer I'll accept it. — Jim Jeffries

Does this answer your question? How do you generate dynamic (parameterized) unit tests in Python? — Dirk Herrmann

Since Python 3.4, the subTest context manager provides a similar functionality:

import unittest class MyTest(unittest.TestCase): def test_my_test(self): inputs = [ (1,2,3), (4,5,9), ] for a, b, c in inputs: with self.subTest(a=a, b=b, c=c): self.assertEqual(a + b, c)
