I’m looking to use:
#define and
#if to allow me to simulate potentially absent hardware during unit tests. What are the rules for using the #define statements?
i.e. what is its default scope? can I change the scope of the directive?
As Chris said, the scope of #define is just the file. (It’s worth noting that this isn’t the same as ‘the class’ – if you have a partial type, it may consist of two files, one of which has symbol defined and one of which doesn’t!
You can also define a symbol project-wide, but that’s done with project properties or a compiler switch rather than being specified in source code.
