Description: Functionality testing is a type of testing that verifies that the software works as expected. These tests focus on evaluating whether the features and functions of the software meet the specified requirements. They are conducted at different stages of the software development lifecycle, from the design phase to implementation and maintenance. Functional tests may include verifying the user interface, APIs, databases, and other system components. Their goal is to identify defects and ensure that the software behaves according to end-user expectations. These tests are essential for ensuring software quality, as they help prevent errors that could affect user experience or cause system failures. Additionally, functional testing is an integral part of various development methodologies, such as agile and DevOps, where continuous and rapid delivery of high-quality software is sought.
