Get a Personalized ShortlistUnit Testing vs. Integration Testing: Key Differences
Feature | Unit Testing | Integration Testing |
---|---|---|
Definition | Tests individual units of code (functions, modules) in isolation to ensure they work as expected according to their specific functionalities. | Tests how multiple individual software components or modules interact and exchange data with each other, ensuring seamless communication and collaboration. |
Focus | Internal logic and behavior of individual code units. | Interoperability and data exchange between components. |
Timing | Usually conducted early in the development cycle, after coding but before other testing stages. | Typically conducted after unit testing and before system testing. |
Test cases | Designed to cover various input scenarios, expected outputs, and error handling within the specific code unit. | Focused on specific interfaces, data flows, and error handling between modules with mockups or stubs for external dependencies. |
Tools used | Mocking frameworks, unit testing frameworks. | Mocking frameworks, integration testing frameworks. |
Outcome | Identifies bugs and errors within individual code units, promoting clean and modular development. | Ensures modules work together properly, data is exchanged correctly, and integration flaws are identified before moving to broader testing. |
Example | Testing if a function calculating shipping costs produces the correct output for different addresses and weights. | Testing whether the order processing system interacts correctly with the inventory and payment modules ensures accurate data transfer. |
Dependencies | Dependent on the accuracy and completeness of unit tests to ensure proper functioning of individual units or components. | Dependent on the stability and correctness of unit-tested components to ensure they integrate seamlessly. |
Automation | Commonly automated using testing frameworks like JUnit, pytest, or NUnit to streamline the testing process. | Frequently automated using integration testing frameworks or tools to facilitate the execution and analysis of integrated components. |
GoodFirms Notes | Unit testing is a "white-box" approach, examining the internal code of individual units. | Integration testing is a "black-box" approach, focusing on the communication and behavior between components without delving into their internal structure. |
