User acceptance testing (UAT) is the ultimate decider of how your target audience will react to your product. Although a type of functional testing, the point at which UAT testing is performed makes it an imperative in the SDLC.

As technology advances faster than ever, software development needs aren't focused on a single platform anymore. Today, each software is developed with the aim to run cross-platform. This is where the need for compatibility testing comes into play.

For the vast majority of software types, you have to test your website’s/application’s compatibility to run on a wide range of devices. How do you do that? How can you make sure that your users can move seamlessly across devices without their experience being hampered in any way?

The software testing process does not end with the segregation of functional and non-functional types. Therefore, to develop a thorough understanding of the SDLC, you need to dig deeper. One of the non-functional testing types is performance testing and this type is further segregated into 4 types.

A Software Development Lifecycle (SDLC) is undoubtedly incomplete without testing. The testing phase comes right after the Post Development Review (PDR) once the documented business rules of a feature are verified. While functional testing focuses on the working of the functional areas of your application, non functional testing provides insights regarding the response of your application under different scenarios.

Apart from being an integral part of the SDLC, functional testing is defined as testing a software system's ability to meet the functional requirements of an end-to-end solution. New to the world of functional testing? You have come to the right place!

Testing plays a vital role in successful software deployment, product releases, or end-to-end solutions building. Both functional and non functional testing hold equal importance in successfully executing the complete SDLC. 

This article will look at the comparative analysis for both of these testing types. Need a more in-depth look at non functional testing first? Check out our comprehensive guide on non functional testing.
