What are the best practices for modularization in software development?

Modularization involves breaking down a program into smaller, manageable modules. Best practices include defining clear interfaces, ensuring high cohesion within modules, and low coupling between them.

Can you explain what high cohesion and low coupling mean?

High cohesion means that the elements within a module are closely related and work together to achieve a single purpose. Low coupling means that modules are independent and changes in one module have minimal impact on others.

What are some common pitfalls to avoid in modularization?

Common pitfalls include creating too many small modules, which can lead to complexity, and not properly defining module boundaries, which can cause confusion.

How can I effectively test modularized code?

You can test modularized code by writing unit tests for each module, ensuring that they function correctly in isolation, and then performing integration tests to check how modules work together.
