Unit testing and system initialisation code I am currently working on testing of some code using a testing tool. As nearly all of the code interacts with the hardware, it is easiest for me to do this on the target. The tool automatically builds the test environment and allows files and/or functions to be tested as a whole or in isolation. In my case, I include all of the project's files in the test builds (so the functionality is available), selecting one of them at a time for white box testing.The only real problem I have is the startup code that exists within main() - this needs to be run to set up the clock tree, initialise the HAL, etc. The testing environment renames main() and adds its own main() so that it can control how the test cases I specify are executed and to allow the results to be captured.At the moment, I have to duplicate the code in the supplied main() so that I can initialise the system before any tests are executed. This is a manual process, which means that the behaviour of this "clone" can diverge fro
