What are some effective integration testing approaches?

There are several effective integration testing approaches, including top-down, bottom-up, sandwich, and big bang testing. Each has its own advantages depending on the project requirements.

Can you explain the top-down approach?

Sure! The top-down approach tests the higher-level modules first and progressively integrates lower-level modules. It allows early detection of interface issues.

What about the bottom-up approach?

The bottom-up approach starts testing from the lowest level modules and integrates upwards. It’s useful for validating individual components before testing the overall system.

Which approach do you recommend for a large project?

For large projects, a hybrid approach like sandwich testing can be effective, as it combines both top-down and bottom-up strategies to ensure comprehensive coverage.
