Why is integration testing important in software development?

Integration testing is crucial because it ensures that different modules or services work together as expected, identifying issues that may not be apparent in unit testing.

What are the main benefits of performing integration testing?

The main benefits include early detection of interface defects, improved software quality, and reduced risk of failures in production.

How does integration testing differ from unit testing?

Unit testing focuses on individual components, while integration testing evaluates the interactions between those components.

Can you give an example of a common integration testing technique?

Sure! One common technique is the 'top-down' approach, where testing starts from the top-level modules and progressively integrates lower-level modules.

What tools are commonly used for integration testing?

Some popular tools include JUnit, TestNG, and Postman for API testing, as well as Selenium for web applications.
