    Why is integration testing important in real-world applications?

    Hi everyone,

    I’ve been exploring integration testing and how it works in real-world projects. From what I understand, integration testing focuses on checking how different modules or systems interact with each other and whether data flows correctly between them.

    Even if individual components work fine, issues can still happen when they are combined. That’s why integration testing is important—it helps identify communication errors and interface issues early.

    In modern development, tools like Keploy make this easier by automatically capturing real API traffic and generating test cases, reducing manual effort and improving test coverage.
