System Testing vs. Integration Testing: Key Differences

FeatureSystem TestingIntegration Testing
DefinitionTests 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.
FocusOverall functionality and behavior of the complete system.Interoperability and data exchange between individual modules.
TimingUsually conducted after integration testing and before deployment.Usually conducted after unit testing and before system testing.
Test casesDesigned 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 usedAutomated testing frameworks, performance testing tools, and security testing tools.Mocking frameworks, integration testing frameworks.
OutcomeIdentifies 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.
AutomationOften 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.
DependenciesDependent 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.
ExampleTesting 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 NotesSystem 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.
