How do I test a layered architecture in software development?

Testing a layered architecture involves validating each layer independently and ensuring they interact correctly. You can use unit tests for individual layers, integration tests for layer interactions, and end-to-end tests for the entire system.

What tools can I use for testing each layer?

For unit testing, tools like JUnit or NUnit are great. For integration testing, consider using Postman or SoapUI. For end-to-end testing, Selenium or Cypress are popular choices.

How do I ensure that the layers are properly decoupled?

You can ensure decoupling by following design principles like Dependency Injection and using interfaces to define interactions between layers. This minimizes direct dependencies.

Can you give an example of a layered architecture?

Sure! A common example is the three-layer architecture: Presentation Layer (UI), Business Logic Layer (Service), and Data Access Layer (Repository). Each layer has distinct responsibilities.
