Key Aspects
Purpose: Verify the software’s functionality by checking user commands, data input, and output.
Scope: Includes testing user interfaces, APIs, databases, security, and client/server applications.
Types: Unit testing, integration testing, system testing, and acceptance testing.
Techniques: Black-box testing is commonly used, focusing on inputs and expected outputs without considering internal code structure.
Benefits
Ensures the application meets the business requirements.
Enhances the quality and performance of the software.
Identifies defects early in the development process.
Functional testing is critical for delivering reliable, user-friendly software, ensuring each feature works correctly in ac
