While working on feature development and releases, I’ve noticed that many issues don’t come from individual components but from how different parts of the system interact with each other. That’s where integration testing becomes really important.

A good integration testing approach helps ensure that new features work smoothly with existing modules, APIs, and services. When combined with smoke testing and end-to-end testing, it gives better confidence before pushing updates live.

It also helps teams catch data flow issues, configuration problems, and dependency failures early in the process, which saves time during later stages of development.

I’m curious to know how others here manage integration testing for new features. Do you follow a structured process, or rely more on manual checks and automation?

Looking forward to hearing your experiences.
