Revising Old Tutorials with The Joy of Testing

Back in 2015 I decided to start doing tutorials for Automation Testing, more precisely with Selenium/Java combination. Although I managed to gather little audience, I did learn a lot. Teaching or transmitting information can be quite an enriching experience. Besides having a good laugh, looking back at my videos makes ponder how much I had improved in those two years.

Testing Tutorials with Rough edges

Although it isn’t one of prettiest works, here’s one my videos, judge for yourself. If you’re wondering how did I come up with the name, it is a reference to Bob Ross’ show “The Joy of Painting”, which I enjoyed watching as a kid.

Sharing knowledge

A lot of people out there may agree that sharing knowledge is a great practice that benefit us all. At a company level, not only help us fill knowledge gaps but also to increase efficiency and promote innovation. At a personal level it helps you grow, stay motivated and get a sense of purpose.

We are fortunate enough to live in a time where sharing knowledge is incredible easy. Thanks to today’s technology we can transmit information to virtually any place in Earth. You can read a book without having a physical copy in your hands or be able to read an article that was written by a guy from the other side of world.

So, my dear reader, I encourage you to share what you know, write a book, a blog, make a video!  Be your sharing knowledge platform Youtube, WordPress, don’t keep what you know to yourself!

Selenium Webdrive in Python Tutorial

Tutorial: Getting Started with Selenium in Python

The best things in life are free, and for Software Testers this is particular true thanks to Selenium. Being a portable testing framework for web applications, Selenium allows us to interact with web elements either without coding skills at all (Recording Tool) or with an easy to learn test domain-specific language (Webdriver). It is perfect for automating the boring stuff!

I’ll show how easy is to get started in Automation Testing using basically only Selenium and Python.

This tutorial assumes that the user is running a similar working environment with the following software:

  • Debian based Linux distribution, like Ubuntu
  • Python 2.7.x
  • Python Pip
  • Firefox 54

Don’t get discouraged if you have an operative system different than Linux. Python and other tools can be installed in other Operative Systems. One of the greatest advantages of these type of software is that they are multi-platform!

Creating an isolated Python environment with Virtualenv

Virtualenv is a tool that allows to create an environment that has it’s own isolated installation of Python and libraries. This is useful if we want to avoid having compatibility issues between projects that require different version of a particular library or simply because we don’t want to mess our global installation.

To install Virtualenv, open a new terminal and type the following command:

pip install virtualenv

Then we create a new folder for your Virtual Environment:

virtualenv selenium

To start using your new virtual environment enter (within your project folder):

source bin/activate

To exit from the your virtual environment, simply type:


Installing Selenium with pip

Once our Virtual Environment is up and running, we can proceed to install Selenium via pip:

pip install selenium

Grabbing Geckodriver

In order to run our tests in Firefox, first we must install the Geckodriver. To check the latest version available visit:

Download the version corresponding to your Operative System and Architecture using wget, example:


Then we uncompress the file:

tar -xvzf geckodriver*

Also we make the file executable:

chmod +x geckodriver

Finally we move the Geckodriver to /usr/local/bin/ so it is accesible for Selenium to use:

sudo mv geckodriver /usr/local/bin/

Running a quick test

Now we are ready to test our environment, let’s write a small script that opens a new browser and navigates to Google:

from selenium import webdriver
browser = webdriver.Firefox()

Feel free to use your favorite code editor, since is a simple script you can even use nano. Once you’re done writing your script, save your changes and go back to Terminal and run your script:


If all went well a new firefox window should open and the browser should display google’s homepage. Congratulations! You wrote your first Selenium Script! Stay tune for more tutorials.
