Did you check the interaction of system components in your last job?

Yes, in my last job I was involved in testing the interaction between system components. This included integration testing, where I checked how modules exchange data and whether they work correctly together.

For this, I used:

• Mock objects to simulate dependencies.
• Integration testing tools, such as Spring Test in Java.
• Logging and monitoring to track calls between components.

This approach helps identify errors at module interfaces and ensures the overall stability of the system.
