If you use WebdriverIO regularly, and you are unfamiliar with the basics of using Applitools for automated visual testing, you will appreciate this course.
I took Nyran Moodie's course on Test Automation University: Automated Visual Testing with WebdriverIO.
If you want the explicit link to the course, here it is https://testautomationu.applitools.com/automated-visual-testing-javascript-webdriverio/index.html.
If you use WebdriverIO regularly, and you are unfamiliar with the basics of using Applitools for automated visual testing, you will appreciate this course. Nyran focuses you on how to add visual test automation with Applitools to your WebdriverIO tests.
Nyran expects you to know WebdriverIO. If you want to learn WebdriverIO, check out Julia Pottinger's excellent course — UI Automation with WebdriverIO on Test Automation University.
Nyran uses JavaScript for his examples and Visual Studio Code as his IDE. In case you didn't know, you can use Applitools with a range of test languages. No matter what your test language of choice or IDE, I think you will find Nyran's code and coding approach fairly intuitive.
Nyran breaks the course into eight main chapters. He gives this description in the course overview:
Each of these chapters provides a methodical approach to getting going with Applitools. I'll give a quick overview of each.
If you read this review or take the course, you know why visual testing. Your UI and end-to-end tests result in the rendered output. You can write all the functional tests that grab locators, enter data, effect action, and cause the appropriate output locators to have the appropriate values. But, until you look at the result, you cannot tell if the input and output conform to design and usability expectations.
Nyran did not explain the most frequently-experienced reason for visual testing — unintended consequences of code changes over time. Our experience shows us that most expected application changes get tested, but unintended changes cause problems.
Nyran does a nice job explaining how to get started. You need an Applitools API key, which you can get from the Applitools console. Nyran explains why you set up a local environment variable for your API key (so you do not need to include your API key in your test code directly). He also points to the GitHub repo he uses for all the examples in the course.
Chapter 3 involves the first coding examples for setting up Applitools. With a simple:
npm install @applitools/eyes.webdriverio
You get the the node instructions for installing the Applitools Eyes to your WebdriverIO setup. After this, you can install the Applitools Eyes service to your tests. He shows code examples of what test code looks like when calling Applitools:

The demand for delivering quality software faster — or “Quality at Speed” — requires organizations to search for solutions in Agile, continuous integration (CI), and DevOps methodologies. Test automation is an essential part of these aspects.
What do you do when you have lots of free time on your hands? Why not learn test programming strategies and approaches?
Feel free to grade your team's maturity through my research. By the end of the article, you'll have your Test Automation Maturity Level.
Regression testing is an essential component in a web application development cycle. but it's often a time-consuming and tedious task in QA process.
There are several reasons why tests become unstable, most of which you can turn around by following these best practices and guidelines.
