What is Functional Testing?
Functional testing is a quality assurance process that evaluates the software system against its functional requirements. It primarily focuses on ensuring that the software performs its intended functions correctly. This type of testing is crucial in identifying any defects or inconsistencies in the functionality of the application.
During functional testing, testers will assess various aspects of software, including user interactions, data manipulation, and integrations with other applications. Test cases are designed based on requirement specifications to verify if the software behaves as expected in different scenarios.
There are several methods of functional testing, including:
- Unit Testing: Tests individual components for correct behavior.
- Integration Testing: Assesses the interfaces and interactions between integrated components.
- System Testing: Validates the complete and fully integrated software product.
- User Acceptance Testing (UAT): Confirms if the software meets business needs and requirements.
Functional testing is essential for delivering high-quality software products, ensuring that users receive a reliable and effective solution to their needs. By systematically verifying each function, development teams can confidently deploy software that meets user expectations and business objectives.
