Functional Testing

Functional Testing is commonly utilized across various phases of software development, particularly during the verification and validation stages to ensure that all functionalities behave as expected before deployment. This methodology is widely applied in industries such as finance, healthcare, telecommunications, and e-commerce, where software applications must meet stringent compliance and user expectations. Testers often execute these tests after unit testing and integration testing but before system testing and acceptance testing, ensuring that any discrepancies from the specified functional requirements are identified early. Participants typically include quality assurance teams, product managers, and developers, all collaborating to define test cases based on the specifications and user stories. Importantly, Functional Testing does not require access to the internal workings of the application, allowing testers to view the product from an end-user perspective, which can lead to discovering usability issues that might not be apparent through code-level testing. This testing can encompass various techniques, including boundary análisis de valor, equivalence partitioning, and user scenario testing, all contributing to a robust assessment of the application’s functionality. Automated testing tools can also support Functional Testing efforts, boosting efficiency and extending coverage across various scenarios without additional manual intervention, thus saving resources and time while increasing reliability in the results.
