Applied after doing a lot of changes, please don't copy code from
audio the library will most likely work differently as we do have
different APIs, also add code that you are actually testing for
example you were only testing part of the GetCapabilities handler and
doing a lot more work than necessary.

So avrcp_send_req does not really help here since it would be just wrapper
for avctp_send functions. Maybe then this unit test is not needed at all?

Check out what I did with ntoh24, you need to check the byte order as
well and create hton24.

I would create a helper function called avrc_send_req which takes the
callback + params and params_len, also Im not sure if it is a good
idea to reuse avctp_rsp_cb or have a different callback so we can
treat AVCTP internally.

OK, what about tests which sends this request, test TP/CFG/BV-01-C.

Which is fine, the capabilities will anyway depend on the underline
player implementation so a dummy one is fine here, in fact the unit
tests should not care what is the capabilities just that the PDU is
formed correctly.

I can implement dummy handlers but this would mean that we are testing
that dummy handlers. Is the idea to test actual production code?

That is the actual AVRCP implementation not the library, the library
only offer means to handle the commands but don't parse it there since
we can't do anything with it. For unit tests you can implement dummy
handlers as we did for passthrough.
