Description: An integration test verifies that different components of an application work together as expected. This type of test is crucial in software development, as it helps identify issues in the interaction between modules or services that may function correctly individually but can fail when integrated. Integration tests focus on the communication between components, ensuring that data flows correctly and functionalities collaborate effectively. They can be performed in various ways, including system integration tests, component integration tests, and continuous integration tests. These tests are essential in agile development environments, where changes are frequent and collaboration among teams is fundamental. By implementing integration tests, developers can detect errors early in the software lifecycle, reducing costs and improving the quality of the final product. Additionally, continuous integration tools facilitate the automation of these tests, allowing them to run every time a change is made to the code, ensuring that the software remains in a functional and stable state over time.
