7 Chrome Extensions for Software Testing – Web UI Testing

Google Chrome browser popularity among both the development and testing community are expected due to the popularity of the browser among Internet users around the world.

Even better when using Edge (Chromium), you can also easily add it to it.

While testing, I use most of the extensions on this list as and when required, and they are actual life-savers.

If you use any particular Google Chrome extension for software testing missing on this list, do let me know in the comments section below, and I will add it here.

1. WhatFont

As testers, we also have to verify cosmetic issues like which font family and font size are used for a particular section on any web page. WhatFont is a simple extension that sticks to its name – easily find fonts on any web page. Hover on any font you want to identify on a web page, showing which font is used. If you need further information about which services are used to serve the web fonts, WhatFont also provides this information.
