Functional Software Testing
Functional software testing is a testing technique that verifies the functionality of a system or application. This is achieved by testing the individual components or features. Functional testing has a focus on evaluating whether the software meets the specified requirements and performs as expected from a user’s perspective. The goal of functional testing is to ensure that the software functions correctly and delivers the intended business value.
Key aspects of functional testing
Test Scenarios: Functional testing begins with identifying and defining test scenarios based on the software’s functional requirements. These scenarios represent specific user actions or system inputs and the expected outcomes.
Test Case Design: Test cases are created based on the test scenarios. They outline a sequence of steps to execute, including the input values, expected results and any preconditions or post-conditions. Each test case aims to validate a particular feature or functionality of the software.
Test Execution: The defined test cases are executed on the software under test. Interaction is achieved by inputting data, triggering actions and observing the corresponding outputs or system behaviour. This can be done manually or through automation tools, depending on the complexity and scope of testing.
Verification of Expected Outcomes: During test execution, the actual results are compared against the expected outcomes specified in the test cases. If the observed behaviour matches the expected results, the test is considered successful. Otherwise, it indicates a defect or a deviation from the expected functionality.
Defect Reporting: When a discrepancy is found between the expected and actual results, a defect is identified. The defect is reported with detailed information, including steps to reproduce the issue, associated test case, environment details and any supporting documentation. This allows the development team to investigate and address the problem.
Regression Testing: As the software evolves through development or maintenance cycles, functional testing ensures that the modifications or enhancements do not introduce new issues or break existing functionality. Regression testing involves retesting previously tested features to ensure their continued correctness after changes.
Test Coverage: This ensures that all critical functions, features and scenarios are adequately tested. This includes positive testing (valid inputs), negative testing (invalid inputs or error handling), boundary testing (testing edge cases), and other relevant test cases.
