Automated visual testing with Selenium and TestNG

Course details

"Automated visual testing" is a buzz word in the IT industry nowadays. In this course I would like to show you what it is and how you can significantly benefit from it.

Automated visual testingis a great complement to functional tests. If something works, it does not mean that it looks fine. Moreover, if something is displayed on the page, it does not necessarily mean that it is displayed in the proper place. Here visual regression can help you.

Let me show you ashort example.

Usually visual regresison is about comparing two images.

The first one is baseline image. This image is the screenshot of the page when it was thouroughly manually tested and was perfect.

The second one is the current appearance of your page. You can take screenshots on daily basis, for example.

If some visualdifferences are detectedthen you getreport where detected differences are highlighted in red.

Thus you can be sure that your web site is looking great anduser interface is not broken by new development. This kind of testing can significantly enhance overall quality of your products.

I hope you liked an idea of automated visual testing. So welcome to my course!
