This commit adds a new Nexus test case 1_3_SRP_TC_3 which implements the test specification for service instance lease renewal and automatic service/host removal. The test covers: - SRP service registration and discovery via DNS and mDNS. - SRP lease renewal before expiration. - Automatic removal of SRP services and hosts after lease expiration. - Verification of DNS and mDNS responses after lease expiration, ensuring that expired records are no longer returned. Changes: - Add tests/nexus/test_1_3_SRP_TC_3.cpp for test execution. - Add tests/nexus/verify_1_3_SRP_TC_3.py for pcap verification. - Update tests/nexus/CMakeLists.txt to include the new test. - Update tests/nexus/run_nexus_tests.sh to add it to DEFAULT_TESTS.

|
|
# To test the following:
|
|
# - 1. Handle name conflict in Host Description record.
|
|
# - 2. Handle name conflict in Service Description record.
|
|
# - 3. Verify that original service is seen when discovering, and conflicting
|
|
# service is not seen on the AIL.
|
|
#
|
|
# 2.2.2. Topology
|
|
# - 1. BR_1 (DUT) - Border Router and the Leader.
|
|
# - 2. ED 1-Test Bed device operating as a Thread End Device, attached to BR_1
|
|
# - 3. ED 2-Test Bed device operating as a Thread End Device, attached to BR_1
|
|
# - 4. Eth 1-Test Bed border router device on an Adjacent Infrastructure Link
|
|
#
|
|
# 2.2.3. Initial Conditions
|
|
# - BR_1 (DUT) should automatically start SRP server capabilities at the
|
|
# beginning of the test.
