Can you explain why?  Something like this can be easily done with pytest:

In [1]: def foo(x):
   ...:     return x + 1
   ...:

In [2]: import pytest

In [3]: @pytest.mark.parametrize('x, y', [
   ...:     (100, 101),
   ...:     (200, 201),
   ...:     (300, 301),])
   ...: def test_foo(x, y):
   ...:     assert foo(x) == y
   ...:

In [4]: test_foo.parametrize.args
Out[4]: ('x, y', [(100, 101), (200, 201), (300, 301)])

In [5]: import random

In [6]: random.shuffle(test_foo.parametrize.args[1])

In [7]: test_foo.parametrize.args
Out[7]: ('x, y', [(200, 201), (100, 101), (300, 301)])
