Debugging And Testing Questions Medium
Dynamic testing is a software testing technique that involves the execution of the software code to evaluate its behavior and performance. It is performed during the software development lifecycle to identify and rectify defects or errors in the software.
There are several techniques used in dynamic testing, including:
1. Unit Testing: This technique focuses on testing individual units or components of the software to ensure that they function correctly. It involves writing test cases for each unit and executing them to verify their behavior.
2. Integration Testing: Integration testing is performed to test the interaction between different modules or components of the software. It aims to identify any issues that may arise due to the integration of these components.
3. System Testing: System testing is conducted to evaluate the behavior of the entire system as a whole. It involves testing the software in an environment that closely resembles the production environment to ensure that it meets the specified requirements.
4. Acceptance Testing: Acceptance testing is performed to determine whether the software meets the user's requirements and is ready for deployment. It involves executing test cases that simulate real-world scenarios to validate the software's functionality.
5. Regression Testing: Regression testing is conducted to ensure that the changes or modifications made to the software do not introduce new defects or impact the existing functionality. It involves retesting the previously tested functionalities to verify their correctness.
6. Performance Testing: Performance testing is used to evaluate the software's performance under different load conditions. It aims to identify any performance bottlenecks or issues that may affect the software's responsiveness and scalability.
7. Security Testing: Security testing is performed to identify vulnerabilities or weaknesses in the software's security mechanisms. It involves testing the software for potential security breaches and ensuring that it adheres to the specified security requirements.
These techniques, when combined, help in identifying and resolving defects or errors in the software, ensuring its reliability, functionality, and performance.
