Functional Testing Services
Don't give any chances to competitors - test the functionality before launchingStart a Project
What is functional testing
Software functionality and performance is an essential thing in how your users respond to your application or software. If, when you are launching the application, it will have serious bugs and issues that users will encounter, then you can at least get low ratings in app stores, bad reviews on the web and also your users will go to your competitors. If the user goes to your competitor - it can hit your earnings a lot.
So, it is necessary to conduct functional testing of the software. Functional testing, which is carried out at an early stage of the development process, will allow:
find problems with inaccessibility
show how well the usability of your application or software works.

Functional Testing Advantages
Functional testing is a large, complex yet must-have part of software development. It is commonly used everywhere if you don't using it means that all other steps of the development cycle were done for nothing since there is no proof everything works as it should. However, if this motivation is not enough, there are lots of other advantages you get.
If you adopt functional testing in your development lifecycle, you'll always be sure your app`s basic features are stable.
There will be no difference between the spec and your live working app.
If you use manual testing for functional tests, you`ll be able to cover 100% of the app with them.
Business requirements are also used as part of the specification for functional tests.

Create test documentation
Execute test cases and log results
Compare actual and expected results of executed tests.
How do you write a test case for functional testing?
When we write test cases for functional testing, each of them has such fields:
A Sequence of steps to execute
What is the difference between regression and functional testing?
The main difference between functional and regression testing is that regression testing is performed after the build is released to verify existing functionality, and functional testing is performed to ensure that all application functions work as required by the documentation.
