Game Development Patterns and Best Practices

Physically decoupling the client and the function call

One aspect of good design is low coupling. We have talked about this a lot before, and it applies here as well. First, since the client is only dependent on the base Command class, it is easier to test. This is because both the client and the specific function calls or actions can be tested independently to ensure that they work. Furthermore, since these unit tests are testing smaller amounts of code, we can be more confident that all possible cases are tested. This also means that the client or the commands have a better chance to be reused because of the low coupling within this project.

Second, the client is less likely to break when changes to the code base occur. Since the client ...
