[PATCH BlueZ 1/2] unit: Add initial tests for sdp_extract_attr()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



These tests do not use the full SDP PDU building code because they try
to catch errors on SDP "extraction" code, which may not appear on a
response PDU (but still cause hard to find bugs).
