What is the primary use case for Node Test Types: E2E, Unit, Integration in Node.js?

It is primarily used to build scalable, non-blocking backend architectures where I/O operations are offloaded to the event loop.

How does this integrate with Express or other web frameworks?

It integrates seamlessly as middleware or a core utility within the route handlers, allowing for high-performance request processing.

What are the common pitfalls when implementing Node Test Types: E2E, Unit, Integration?

Developers often forget to handle asynchronous errors or improperly manage memory, leading to memory leaks and blocked event loops.
