From d44de4e418150f7520d90a85a33b45b5f08cb1cd Mon Sep 17 00:00:00 2001 From: Jonathan Hui Date: Thu, 19 Feb 2026 00:34:42 -0600 Subject: [PATCH] [nexus] add test 7.1.1 Network Data Propagation (#12492) This commit adds a new Nexus test case for 'Network data propagation' (7.1.1) as specified in the Thread Test Specification. The test verifies that the DUT, acting as a Border Router and Leader, correctly sets Network Data (stable and non-stable) and successfully propagates it to various child types (Router, MED, and SED) during the attach and child update processes. Summary of changes: - tests/nexus/test_7_1_1.cpp: Implements the test logic. - Configures a network with a Leader (DUT), Router_1, MED_1, and SED_1. - Sets up On-Mesh Prefixes on the Leader (one stable, one non-stable) and registers them. - Sequentially attaches Router_1, SED_1, and MED_1. - Advances time to allow for MLE Child ID and Child Update exchanges. - Uses direct core method calls and sets log level to note. - tests/nexus/verify_7_1_1.py: Python PCAP verification script. - Verifies MLE Advertisements from the Leader. - Validates MLE Child ID Responses to Router_1 and MED_1 contain both prefixes. - Validates MLE Child ID Response to SED_1 contains only the stable prefix and ensures P_border_router_16 is 0xFFFE. - Verifies the Child Update exchange with required TLVs for MED_1 and SED_1. - tests/nexus/CMakeLists.txt: Added the new test to the build system. - tests/nexus/run_nexus_tests.sh: Added 7_1_1 to the default test list. --- tests/nexus/CMakeLists.txt | 1 + tests/nexus/run_nexus_tests.sh | 1 + tests/nexus/test_7_1_1.cpp | 241 +++++++++++++++++++++++++++++++++ tests/nexus/verify_7_1_1.py | 204 ++++++++++++++++++++++++++++ 4 files changed, 447 insertions(+) create mode 100644 tests/nexus/test_7_1_1.cpp create mode 100644 tests/nexus/verify_7_1_1.py diff --git a/tests/nexus/CMakeLists.txt b/tests/nexus/CMakeLists.txt index b91d6f7f2..b9cb00a31 100644 --- a/tests/nexus/CMakeLists.txt +++ b/tests/nexus/CMakeLists.txt @@ -171,6 +171,7 @@ ot_nexus_test(6_2_2 "cert;nexus") ot_nexus_test(6_3_1 "cert;nexus") ot_nexus_test(6_3_2 "cert;nexus") ot_nexus_test(6_4_1 "cert;nexus") +ot_nexus_test(7_1_1 "cert;nexus") # Misc tests ot_nexus_test(border_admitter "core;nexus") diff --git a/tests/nexus/run_nexus_tests.sh b/tests/nexus/run_nexus_tests.sh index c7fc3d0cf..bb805c5e3 100755 --- a/tests/nexus/run_nexus_tests.sh +++ b/tests/nexus/run_nexus_tests.sh @@ -107,6 +107,7 @@ DEFAULT_TESTS=( "6_3_2" "6_4_1_A" "6_4_1_B" + "7_1_1" ) # Use provided arguments or the default test list diff --git a/tests/nexus/test_7_1_1.cpp b/tests/nexus/test_7_1_1.cpp new file mode 100644 index 000000000..498127dbc --- /dev/null +++ b/tests/nexus/test_7_1_1.cpp @@ -0,0 +1,241 @@ +/* + * 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.
