Functional testing is a software testing approach that assesses applications against functional requirements to identify defects. It involves several steps, including identifying expected functions, creating input data, executing test cases, and comparing outputs. Different types of functional testing include smoke testing, sanity testing, regression testing, and user acceptance testing, all of which are essential for ensuring the software meets user demands and quality standards.

- 2. QA InfoTech What is Functional Testing? Functional testing is a type of software testing in which software is tested against functional requirements/specifications with the intend to find a bug/defect(s) if any. Functional testing is different from system testing as functional testing verifies a program by checking it against the design document while system testing validates a program by checking it against the published user or system requirement. Functional testing consist of six steps- 1. The identification of functions that the software is expected to perform 2. The creation of input data set based on the function's specifications 3. The determination of output based on the function's specifications 4. The execution of the test case 5. The comparison of actual and expected output 6. To check whether the application works as per the customer’s need.

- 4. QA InfoTech Smoke Testing:- Smoke testing is conducted to check the stability of a build. It is the initial phase of testing to ensure whether a build is in a testable condition or not. Sanity Testing:- Sanity testing is conducted to check the high-level features of a software. It is performed as a subset of regression testing to ensure that the software performs as per the given requirements.
- 5. QA InfoTech Regression Testing:- Regression testing is conducted after a developer fixes the piece of code which is bug infected. While doing regression testing, mainly the focus is on the broken feature and other related areas of that feature. UAT (User Acceptance Testing):- UAT is performed by the end users/Client to verify whether the system is working as per the given requirements or not. In other words, software is tested in the "real world" by the intended audience.
- 6. QA InfoTech Functional Testing @ QAInfoTech Functional testing is a key element for enhancing the quality of the developed software. The risks of releasing a new product without rigorous quality assurance have greater implications now than ever before because of the ever-changing expectations and demands of the end users. Finding independent QA and testing vendors, who are not biased by the development unit, is crucial to the success of a quality product. At QA InfoTech, we value this, and being an independent software testing company we believe in transparency. Our objective is to measure the performance quality of the functional components. We practice a thorough framework based methodology when conducting functional, GUI, database and regression testing. Our centers of excellence have helped multiple enterprises to implement an organized approach in automation functional testing services. We have leveraged our internal framework with the right mix of automation tools and our home-grown methodologies, resulting in not just repeatability and optimum time utilization but also in bringing combinatorial testing wherever possible by combining functional test scripts with areas such as performance, security, localization, accessibility etc.
