Creating a data-driven test in Python

Python is also a widely used language for building Selenium WebDriver tests. It offers various ways to parameterize tests.

In this recipe, we will parameterize a Selenium WebDriver test written in Python, using a CSV file.

How to do it...

Let's create a simple Python test for parameterization, using the following steps. This test will read test data from the CSV file used in the Reading test data from a CSV file using JUnit recipe earlier.

1. Create a Ruby test by importing the following modules:

   from selenium import webdriver
   import csv, sys

2. Declare the following variables to print a summary of the test combinations executed from the test data source:

   #Variables for Printing Test Summary
   test_executed = 0
   test_passed = 0
   test_failed = 0
   test_status = True

3. Add the following code, which will iterate through the CSV data by reading each combination and then performing the operations and verifications:

   try:
     #Create an instance of WebDriver for Firefox
     driver...
