Intel net test suite for LwIP network stack
This project provides a test interface to esp32 network stack in order to execute standard set of Intel network test suite defined in TTCN3 framework.
Important notice
This is an internal ESP-IDF test and not a user project example
Execute net test suite
These network tests could be executed in both manual or automated mode in CI.
Note: TTCN3 engine works reliably only on Linux and Windows.
Setup TTCN3
- Clone a repository https://github.com/intel/net-test-suites.git and install titan core as described in the README.md
- Copy files
esp32_netsuite.cfg
andesp32_netsuite.ttcn
(located in$IDF_PATH/components/lwip/weekend_test
) tosrc
subdir of the cloned repositorynet-test-suites
- Rebuild the netsuite tests (according to README.md in net-test-suite) by executing
source make.sh
insrc
subdir
Build application
cd $IDF_PATH/examples/system/network_tests
idf.py build
idf.py -p PORT flash
Run test
Open two terminals (1) and (2)
- Start the test server which would pass packets from TTCN3 test suite into ESP32 board in
$IDF_PATH/components/lwip/weekend_test
python net_suite_test.py
- Start test suite in TTCN3 environment in
src
subdir of the cloned repositorynet-test-suites.git
ttcn3_start test_suite esp32_netsuite.cfg
Internal connection
Purpose of this test is to execute standard network suite on a ESP32 network stack.
DUT, Device (Network stack in this case) under test, runs normally on target, but a specific interface with configured esp-netif for passing arbitrary data to
and from the network stack. Embedded code net_suite.c
implements an application which serves stdin/stdout and propagates the data to/from this test interface.
Standard Intel net suite executed by TTCN3 engine uses udp ports for input/ouput of network packets. Python script net_suite.py
translates this communication
from/to those udp ports to stdin/stdout, where after propagating over USB/UART to the ESP32 board are processed in the network stack (on the target).
Actual test execution, progress, evaluation and test reporting is done using standard net-test-suite scripts running on PC.
