Solve the following python programming problem given the following code:
@ pytest.mark.parametrize ('input,expected', [('foo', ['foo']), (['foo'], ['foo']), (['foo', 'bar'], ['foo', 'bar'])]) 
def test_command(input, expected) : 
    @ decorators.command (input) 
    def foo() : 
        pass 
assert (input.commands == expected)
