In this lesson, you will learn:

  • What is parametrization.
  • Why we need parametrization.

You can find the scripts and code for this lesson within the Pytest repo under the directory: 004_parametrization/001_no_parametrization.

Testing Without Parametrization

Based on what we have learnt, let’s say we wanted to test for multiple VLANs on a device. To do so, we could write our test like this:

import pytest

def expected_vlan():
    return ["100", "101", "102"]

def device_vlans():
    return ["100"]

def test_vlan(expected_vlan, device_vlans):
    for vlan in expected_vlan:
        assert vlan in device_vlans
