Get a Personalized ShortlistSystem Testing vs. Integration Testing: Key Differences
Feature | System Testing | Integration Testing |
---|---|---|
Definition | Tests the entire software system to ensure it meets functional and non-functional requirements and interacts seamlessly with other systems. | Tests the interactions and communication between individual software components or modules to ensure they work together correctly. |
Focus | Overall functionality and behavior of the complete system. | Interoperability and data exchange between individual modules. |
Timing | Usually conducted after integration testing and before deployment. | Usually conducted after unit testing and before system testing. |
Test cases | Designed to cover various user scenarios, system functionalities, and non-functional aspects like performance and security. | Focused on specific interfaces, data flows, and error handling between modules. |
Tools used | Automated testing frameworks, performance testing tools, and security testing tools. | Mocking frameworks, integration testing frameworks. |
Outcome | Identifies system-level issues, ensures all functionalities work together as expected, and verifies compliance with requirements. | Ensures modules work together properly, data is exchanged correctly, and integration flaws are identified. |
Automation | Often automated to streamline testing processes and ensure thorough coverage of system functionalities and scenarios. | Frequently automated using testing frameworks and tools to facilitate the execution of integration tests across different configurations. |
Dependencies | Dependent on completing integration testing to ensure that integrated components or systems function correctly. | Dependent on completing unit testing to verify the correctness and stability of individual components before integration. |
Example | Testing if an online shopping system allows users to complete purchases, integrates smoothly with payment gateways, and delivers orders effectively. | Testing whether the order processing module interacts correctly with the inventory and payment modules ensures accurate data transfer. |
GoodFirms Notes | System testing is often called "black-box" testing as it focuses on the system's external behavior without delving into internal code. | Integration testing is a "white-box" approach, examining the internal interactions between components. |
