Integration Testing vs. End-to-End (E2E) Testing: A Comprehensive Comparison

In software testing, multiple strategies help ensure the quality and stability of an application. Among the most critical approaches are Integration Testing and End-to-End (E2E) Testing . Although both aim to catch issues in an application, they target different layers and serve unique purposes. Understanding the distinction between these two methods is essential for implementing an effective testing strategy. In this article, we’ll explore integration vs e2e testing , their key differences, when to use each, and best practices. What is Integration Testing? Integration Testing focuses on testing the interaction between different modules or components of an application. It is typically done after unit testing and aims to verify that multiple components work together as expected. While unit tests check individual pieces of code in isolation, integration tests ensure that these individual pieces can function harmoniously when combined. Goals of Integration Testing: Validate ...
