Functional testing is used for quality assurance (QA). Function testing describes what a system does. There are five steps involved with functional testing.
Validation testing is to test software if it meets its stated requirements. System testing is the testing of Software and Hardware together and to find out they both can work together to be successful application.
It is testing of "how" the system works. Non functional testing may be performed at all test levels. The term non-functional testing describes the tests required to measure characteristics of systems and software that can be quantified on a varying scale, such as response times for performance testing. Types of Non-functional testing are performance testing, load testing, stress testing, usability testing, maintainability testing, reliability testing and portability testing.
System testing has classifications like functional and non functional testing. Hence the functional testing is a part of system testing. System testing allows the testers to test the typical end product. Every single module, interface and every minute detail are needed to be tested in system testing. Functional testing is aimed at testing the functionalities of the product being tested. These functionalities include volume, stress, load, security, scalability, performance etc. Hardware and software is not concerned with functional testing. Functional testing involves testing of functional requirements as per the specification. On the other hand, system testing involves testing the system as a whole. This may involve testing of proper installation and uninstalling of the application. System testing tests for all internal and external components that make the system.
Regression testing is a type of software testing that seeks to uncover new software bugs, or regressions, in existing functional and non-functional areas of a system after changes such as enhancements, patches or configuration changes, have been made to them.
Functional Testing
A comprehensive functional fitness testing protocol typically includes assessments of strength, endurance, flexibility, balance, and agility. These components help evaluate overall physical fitness and identify areas for improvement in an individual's functional abilities.

Mobile testing : Mobile Testing encompasses mobile application testing, mobile device testing, mobile phone testing, mobile system testing.Mobile application testing : Mobile application testing is a process by which application software developed for hand held mobile devices is tested for its functionality, usability and consistency. Mobile applications either come pre-installed or can be installed from mobile software distribution platforms. Mobile devices have witnessed a phenomenal growth in the past few years.
To ensure effective implementation of PBE functional testing in our software development lifecycle, we should establish clear testing objectives, define test cases based on user behavior, automate testing processes where possible, regularly review and update test cases, involve stakeholders in testing, and continuously monitor and improve the testing process.
Yes there are many. But make sure you partner with someone who can provide customized core testing services. Look for companies offering customized testing at multiple levels including functional testing, integration testing, and regression testing.
It's a type of GUI testing where functionality of an application is tested.To be specific:Testing of all features and functions of a system [software, hardware, etc.] to ensure requirements and specifications are met.Functionality testing of software is testing conducted on a complete, integrated system to evaluate the system's compliance with its specified requirements. Functionality testing falls within the scope of black box testing, and as such, should require no knowledge of the inner design of the code or logic
