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.

2. ColorZilla

ColorZilla is a colour picker chrome extension that allows you to find the exact colour used on any web page right within the Chrome browser. ColorZilla is useful when you test whether the colour used on a web page matches design specifications.

3. PerfectPixel

If you are my kind of tester who expects the application-under-test to be pixel perfect as per design specs (Conditions apply ;)), this extension is for you! PerfectPixel allows you to make sure your application matches the design pixel for pixel. You can put a semi-transparent image overlay over the top of your web page, using which you can do a per-pixel comparison.

4. IE Tab

IE tab chrome extension is one of the most popular IE browser emulators. Using IE Tab, you can test web pages with different versions of IE without leaving your favourite Chrome browser.

It is a simple chrome extension for copy-verification during web testing and supports 12 languages. You can also add your own words to the dictionary.

6. Grammarly

If you aren’t already aware of this great tool, Grammarly is a great utility that helps you proofread text wherever you write online – mail, comments or blog post. As you write, Grammarly checks spelling and grammatical errors and highlight them without leaving the browser. For testing, Grammarly is a free chrome extension that brings the grammar-checking power of Grammarly right into your Chrome browser.

7. Screen Ruler DISCONTINUED 🙁

Screen Ruler is a simple chrome extension that does what it says on the tin. Using Screen Ruler chrome extension while testing, you can measure object height, width, the padding on either side by simply placing it over the element and dragging it to draw out a ruler in the desired direction.
