Hands-On RTOS with Microcontrollers

Queues make testing easier

Similar to the way hardware abstractions provide easy insertion points for test data, queues also provide excellent places to enter test data. This provides a very convenient entry point for entering test data for code under development. The flexibility of implementation mentioned in the previous section also applies here. If a piece of code is sending data to a queue and expects a response from another queue, the actual implementation doesn't necessarily need to be used—it can be simulated by responding to the command. This approach makes it possible to develop the other side of code in the absence of fully implemented functionality (in case the hardware or subsystem is still under development). This approach is ...
