Functional Testing Services

No software system can be strengthened until and unless it’s functional testing is done. Usually implemented at the early stages of the development to ensure software stability till the end.

Functional testing is directly related to the app functionality and its users. Meticulous system evaluation by using functional testing is conducted at various levels and utilizing different testing types like unit testing, system testing, integration testing etc.

When Should You Automate Functional Tests?

One of the simplest answers is, it reduces time and effort, especially in cases where on-time product launch is crucial. Also, this prevents ‘human-error’ to skip. However, formulating the right test cases is important along with finding the right automation tools.

Automation of functional tests is needed when you have to run similar test cases on multiple platforms and devices. Also, if there is a need to run a 24/7 check on functionalities, this can be done without human intervention or dependency.

Functional Testing for Different Platforms


By running tests against your app consistently, you can verify your app's correctness, functional behavior, and usability before you release it publicly. You can manually test your app by navigating through it.


Testing on iOS devices for functional behavior and see whether expected results are achieved via the developed app or not.


Compatibility testing and regular functional testing on Windows and see if the app is working smoothly and not breaking.


Usage of tools, automated and manual testing for the developed app functional requirements thorough testing.

Mac OS

Seeing how many versions of the Mac does the developed app support and looking into the functional features of the app.
