From c5006b09b96296af351e7174d2a30aa9b9208b96 Mon Sep 17 00:00:00 2001 From: Jonathan Hui Date: Fri, 20 Feb 2026 23:21:27 -0600 Subject: [PATCH] [nexus] add test 5.6.6 Network data expiration (#12506) This commit adds a new Nexus test case for 'Network data expiration' (5.6.6) as specified in the test specification. The test verifies that network data is properly updated when deleting a prefix or removing a server from the network. Summary of changes: - Implemented Nexus test 5.6.6: - Added tests/nexus/test_5_6_6.cpp: Implements the test execution including topology formation, on-mesh prefix configuration, and silent power-off of a border router. The test uses direct method calls, sets log level to note, and uses AllowList for connectivity. - Added tests/nexus/verify_5_6_6.py: PCAP verification script. Validates CoAP Server Data notifications, MLE Data Responses, and Child Update exchanges, ensuring correct network data propagation and expiration. - Updated build and execution scripts: - Modified tests/nexus/CMakeLists.txt to build the new test. - Updated tests/nexus/run_nexus_tests.sh to include 5_6_6 in the default test list. --- tests/nexus/CMakeLists.txt | 1 + tests/nexus/run_nexus_tests.sh | 1 + tests/nexus/test_5_6_6.cpp | 467 +++++++++++++++++++++++++++++++++ tests/nexus/verify_5_6_6.py | 390 +++++++++++++++++++++++++++ 4 files changed, 859 insertions(+) create mode 100644 tests/nexus/test_5_6_6.cpp create mode 100644 tests/nexus/verify_5_6_6.py diff --git a/tests/nexus/CMakeLists.txt b/tests/nexus/CMakeLists.txt index 75f715197..937518dab 100644 --- a/tests/nexus/CMakeLists.txt +++ b/tests/nexus/CMakeLists.txt @@ -160,6 +160,7 @@ ot_nexus_test(5_6_2 "cert;nexus") ot_nexus_test(5_6_3 "cert;nexus") ot_nexus_test(5_6_4 "cert;nexus") ot_nexus_test(5_6_5 "cert;nexus") +ot_nexus_test(5_6_6 "cert;nexus") ot_nexus_test(5_7_1 "cert;nexus") ot_nexus_test(5_7_2 "cert;nexus") ot_nexus_test(5_7_3 "cert;nexus") diff --git a/tests/nexus/run_nexus_tests.sh b/tests/nexus/run_nexus_tests.sh index ff237ed95..6d60cd01a 100755 --- a/tests/nexus/run_nexus_tests.sh +++ b/tests/nexus/run_nexus_tests.sh @@ -90,6 +90,7 @@ DEFAULT_TESTS=( "5_6_3" "5_6_4" "5_6_5" + "5_6_6" "5_7_1" "5_7_2" "5_7_3" diff --git a/tests/nexus/test_5_6_6.cpp b/tests/nexus/test_5_6_6.cpp new file mode 100644 index 000000000..19f936012 --- /dev/null +++ b/tests/nexus/test_5_6_6.cpp @@ -0,0 +1,467 @@ +/* + * Copyright (c) 2026, The OpenThread Authors. + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions are met: + * 1.
