This does not necessarly have to match.<br>Accessing the array elements directly was the prefered way when the MGW<br>did use integer numbers and not strings to identify endpoints. Since the<br>endpoint name strings are used to access the endpoints the unit-test<br>should also reflect this.<br><br>Lets replace the integer variable last_endpoint with a string variable<br>and do related verifications based on strings.<br><br>Change-Id: Ic950c427f23be4a792af94972554637c2b0fbdf2<br>Related: OS#2659<br>---<br>M tests/mgcp/mgcp_test.c<br>1 file changed, 31 insertions(+), 31
