Ready For Release? Test It First With Our Functional Testing Services
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. Software 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.
That's why this type of testing is a crucial element of software development. Moreover, functional testing shows whether your software works as you expected.
Functional Testing Types
When we provide functional testing , we are ready to offer our clients both manual testing and automated testing services. The main types of functional testing that we perform are:
As a result of smoke testing is checking whether your app is stable enough for further testing.
Testing of individual functions of the application or software.
Testing groups of functions to detect errors during their interaction.
Testing of all functions.
Software testing in real scenarios is performed to ensure compliance with specifications.
Testing of software functions after the upgrade, so that the changes do not affect the previously working functions.

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 use 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.

User Acceptance Testing
Black Box Testing
White Box Testing
How do you conduct functional testing?
To do a proper functional testing, QA engineer needs to fully understand the process and build it around the following scheme:
Select features that need to be tested and order in which they should be tests.
Define test input (test data)
Compute the expected output with selected test data
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.
