Get a Personalized ShortlistIntegration Testing vs. Regression Testing: Key Differences
Feature | Integration Testing | Regression Testing |
---|---|---|
Definition | Verifies that multiple individual software components or modules function correctly together and exchange data as expected. | Determines if recent changes (like bug fixes or new features) have introduced unintended errors or regressions in existing functionalities. |
Focus | Interoperability and communication between components | Overall functionality and behavior of the system after changes. |
Timing | Usually conducted after unit testing and before system testing. | Performed after any significant change to the codebase before deployment. |
Test cases | Designed to test data flow, interactions, and communication between modules. | Focused on existing functionalities and scenarios that changes might impact. |
Tools used | Mocking frameworks, integration testing frameworks. | Automated testing frameworks and regression testing tools. |
Outcome | Ensures modules work together seamlessly and exchange data correctly. | Identifies regressions caused by changes and ensures existing functionality remains intact. |
Example | Testing if an order processing system interacts correctly with the inventory management and payment gateway modules. | Testing if a new login feature doesn't affect existing user functionalities. |
Automation | Can be partially or fully automated using integration testing tools and frameworks to streamline the testing process. | Often automated to facilitate frequent and efficient testing of existing functionality across multiple scenarios. |
Dependencies | Dependent on the availability and stability of individual components and their interfaces for successful testing. | Dependent on the accuracy and completeness of the regression test suite to provide reliable results. |
