The purpose of regression testing is to ensure that changes or updates in a software application do not negatively impact its existing functionalities. It involves re-running functional and non-functional tests to ensure that previously developed and tested software still performs correctly after a change. Regression testing can help catch bugs early and prevent the introduction of new defects.
For example, if a developer fixes a bug in a login module, regression testing would involve testing not just the login functionality but also other parts of the application that might be affected by the change, such as user profiles, account settings, or even third-party integrations.
In the context of cloud computing, regression testing is crucial when deploying updates or new features to cloud-based applications. It ensures that the application remains reliable and performs as expected under various conditions and scales.
For cloud-based regression testing, services like Tencent Cloud offer robust solutions. Tencent Cloud's Cloud Testing service provides a comprehensive set of tools for automated testing, supporting various testing scenarios including regression testing. It leverages the scalability and flexibility of the cloud to handle large volumes of tests efficiently, ensuring that applications remain stable and performant as they evolve.
