Do you write your code using dynamic language programming techniques? Or do you use functions and no objects? The answer is that you use all of the aforementioned techniques and then some. JavaScript represents an evolution in programming capabilities. Sure, some things do not work as they would in a traditional programming language, but that does not mean there is a problem.

The client and server interact with each other using contracts. Using contracts, you can develop the client independently and test it using mock objects. Using contracts, you can develop the server independently and test it using tests from a test suite. Then when the client is combined with the server, the application will work without requiring a large amount of further testing. Of course, this assumes that the tests for the client and server are implemented properly— normal testing is often also required.

The test layer 3 doesn’t depend on or care about how the logic is exposed to the HTTP protocol. The tests in layer 3 focus on making sure that the server-side logic is implemented correctly. The contracts that the tests verify are not exposed externally, and the client doesn’t care what the tests are. Because the tests are private, the server developer can define their class structure, using whatever technology desired without affecting the client. org): Java test-driven development framework. JUnit is the original unit-testing tool.
