Difference between Unit Testing and Integration Testing in Test Automation

In test automation, the key distinction between unit testing and integration testing lies in the scope of the tests. Unit testing focuses on individual units or components of the code, testing their functionality in isolation. On the other hand, integration testing involves testing the interactions between these units or components to ensure they work correctly when combined.

Unit testing aims to validate the smallest parts of the code, typically at the function or method level, to ensure they perform as expected. This helps in detecting defects early in the development process and promoting code quality.

Integration testing, on the other hand, checks how different units or modules interact with each other and how well they integrate to form a complete system. It ensures that the components work together seamlessly and meet the desired functionality as a whole.

Both unit testing and integration testing are crucial aspects of test automation, with unit testing focusing on individual components and integration testing ensuring the proper collaboration between these components.

By incorporating both unit and integration testing in test automation strategies, teams can enhance the overall quality and reliability of their software products.
