180+ Sample Test Cases for Testing Web and Desktop Applications – Comprehensive Testing Checklist

This is a Testing Checklist for both webs as well as desktop applications.

Note – This article is a little lengthy one (over 2700 words). However, my goal is to share one of the most comprehensive testing checklist ever written and this is not yet done. I’ll keep updating this post in the future as well with more scenarios. If you don’t have time to read it now, please feel free to share this with your friends and bookmark it for later.

Make testing checklist as an integral part of your test case writing process. Using this checklist, you can easily create hundreds of test cases for testing web or desktop applications.

These are all general test cases and should be applicable for almost all kind of applications. Refer these tests while writing test cases for your project and I’m sure you will cover most of the testing types except the application specific business rules provided in your SRS documents.

Though this is a common checklist, I recommend preparing a standard testing checklist tailored to your specific needs using below test cases in addition to application-specific tests.

What You Will Learn:

Importance of Using Checklist for Testing

#1) Maintaining a standard repository of reusable test cases for your application will ensure that most common bugs will be caught more quickly.

#2) A checklist helps to complete writing test cases quickly for new versions of the application.

#3) Reusing the test cases help to save money on resources to write repetitive tests.

#4) Important test cases will be covered always, thereby making it almost impossible to forget.

#5) The testing checklist can be referred by developers to ensure if the most common issues are fixed in the development phase itself.

Few Notes to Remember:

– Execute these scenarios with different user roles e.g. admin user, guest user etc.

– For web applications, these scenarios should be tested on multiple browsers like IE, FF, Chrome, and Safari with versions approved by the client.

– Test with different screen resolutions like 1024 x 768, 1280 x 1024, etc.

– An application should be tested on a variety of displays like LCD, CRT, Notebooks, Tablets, and Mobile phones.

– Test application on different platforms like Windows, Mac, Linux operating systems etc.

Penetration testing test cases – I’ve listed around 41 test cases for penetration testing on this page.

I ‘d really like to thank Devanshu Lavaniya (Sr. QA Engineer working for I-link Infosoft) for helping me to prepare this comprehensive testing checklist.

I’ve tried to cover almost all standard test scenarios for web and desktop application functionality. But still, I know that this is not a complete checklist. Testers on different projects have their own testing checklist based on their experience.

Please feel free to make this a complete checklist by adding more test scenarios or negative test cases in the comments section below.

Also, I’d appreciate if you’d share this with your friends as well!
