Functional Testing Explained With Examples
What is Functional Testing?
Functional testing is a type of testing that checks if an application's features meet the requirements. It is very important in manual QA since directly validating the end-user features' behavior is the main impact of the testing.
Some instances of functional testing are:
- Login and authentication testing – Confirming the correctness of the username, password, and validation messages.
- Form submission testing – Testing input fields, error handling, dropdowns, and so forth to be sure they are working fine.
- Workflow testing – Looking into different actions including those done during checkout or onboarding.
- API integration testing – Seymour-ing the data flow among the different modules.
These scenarios highlight the value of functional testing as a services delivered by a reliable functional testing company.
Regression Testing Processes and Tools
What is regression testing?
It ensures that existing functionality remains stable after updates or fixes—making regression testing in software critical for fast-moving products.
Testing updates to ensure existing capabilities work without interruption is called regression testing. It's a requirement for many business services, FinTech products, and fast-paced development environments. During the regression testing process, QA teams test their software by rerunning previous test cases to make sure it works properly.
Testing tools for regression testing:
- TestRail for managing test cases
- Jira + Zephyr for managing regression testing cycles
- Qase for managing regression testing in teams that implement Agile
- Azure Test Plans – for managing manual test cases, regression suites, and test execution within Azure DevOps
