File structure to satisfy both building and testing?

Update: I figured out how to get Platform IO to stop gathering irrelevant dependencies from src/main.cpp during testing! No need to manually ignore them via lib_ignore!

platformio.ini

[env:desktop]
platform = native
lib_ldf_mode = chain+

src/main.cpp

#ifndef PIO_UNIT_TESTING

...

#endif  // PIO_UNIT_TESTING

(The + in chain+ makes it respect directives like #ifndef when determining dependencies.)
