Functional testing is a process of testing all the functionality of an application.When we create a software, we create it keeping the users of that software in mind. Functional testing test whether the application fulfills the requirement of the user.
It means to check whether the functionality of an application are working as expected or not.
For example, Login functionality, Compose mail functionality, Delete mail functionality,etc.

What is non functional testing in software testing?
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.
What is the difference between validation testing and system 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.
What is the Difference between functional and functionality 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.
What is full regression testing?
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.
When do you do functional testing?
Functional testing is performed after the software application has been developed and is ready for verification. This type of testing checks the application's features and functionalities against specified requirements to ensure they work as intended. It typically occurs during various stages of the software development lifecycle, including during unit testing, integration testing, and system testing. Additionally, functional testing is crucial before a product is released to ensure it meets user expectations and requirements.

What is functionality 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
Difference between integration testing and regression testing?
Integration testing - It is the phase of software testing in which individual software modules are combined and tested as a group. It follows unit testing and precedes system testing.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.
What is pilot testing in software?
Functional testing is a process of testing all the functionality of an application.When we create a software, we create it keeping the users of that software in mind. Functional testing test whether the application fulfills the requirement of the user. It means to check whether the functionality of an application are working as expected or not. For example, Login functionality, Compose mail functionality, Delete mail functionality,etc. See the related question below.
What is the purpose of a software test?
Software testing is carried out to ensure that the software package is capable of performing the necessary requirements for it's purpose. It should be carried out before the release of the software to the customer. Functional, parametric, integration and regression testing should all be included.
How can we ensure that the PBE functional testing process is effectively implemented within our software development lifecycle?
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.
What is Unified functional testing?
Unified Functional Testing (UFT) is a software testing tool developed by Micro Focus that enables automated functional and regression testing for various applications. It supports a wide range of technologies, including web, mobile, and enterprise applications, allowing testers to create and execute automated test scripts. UFT uses a keyword-driven approach, making it accessible for users with varying levels of programming expertise. Its integration with other testing tools and frameworks enhances its capabilities in ensuring software quality and reliability.
