Framework used by Native platform

[mithradir]

I finally started to add some unit tests for a library I’m working on and had some trouble figuring out why pio test whould ignore my dependencies when using the Native platform. Turns out my dependency specified framework = "arduino" causing it to be rejected. Either setting lib_compat_mode = off in my project or changing the dependency config to framework = "*" fixed this problem but I am not a big fan of either solution.

This leaves me with the following question: What would be a framework to add for compatibility with the Native platform? I saw examples of setting board in conjunction with platform = native but never framework. Is there no such thing for the Native platform?

Setting lib_compat_mode = off only for the native environment used for unit tests seems to be the least invasive solution I can see but would only work with dependecies not really requiring a specific framework.
At least for the Arduino framework there seems to be a solution using ArduinoFake as recommended in this discussion:

Getting started with unit testing

That topic might by a bit more complicated than you have anticipated. The first error stems from the LDF rejecting the full inclusion of the library because it sees that it needs framework = arduino or mbed which is not set in the native environment, since there is no Arduino there normally. That is worked around by adding lib_compat_mode = off. Next, you will see that even if you only include the IoAbstraction.h header, it will still ask for the Arduino headers in this library and its depende…

Any thoughts or recommendations are certainly welcome

What happens when you declare the library’s platforms value to be compatible with native?

[mithradir]

If my dependency’s library.json contains frameworks: "arduino", "platforms": "native" the LDF will reject that library unless I set lib_compat_mode = off for the environment used by pio test. Changing eighter the lib_compat_mode or frameworks works.

I think then there should be a special framework value standing for none or baremetal – I think because the projects using platform = native have no framework = .. line, technically the framework string is empty and fails to match a list of frameworks, except * of course.
