# 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` and `esp32_netsuite.ttcn` (located in `$IDF_PATH/components/lwip/weekend_test`) to `src` subdir of the cloned repository `net-test-suites`
|
|
* Rebuild the netsuite tests (according to README.md in net-test-suite) by executing `source make.sh` in `src` subdir
|
|
|
|
|
|
## Build application
|
|
|
|
```
|
|
cd $IDF_PATH/examples/system/network_tests
|
|
idf.py build
|
|
idf.py -p PORT flash
|
|
```
|
|
|
|
## Run test
|
|
Open two terminals (1) and (2)
|
|
1) Start the test server which would pass packets from TTCN3 test suite into ESP32 board in `$IDF_PATH/components/lwip/weekend_test`
|
|
```
|
|
python net_suite_test.py
|
|
```
|
|
|
|
2) Start test suite in TTCN3 environment in `src` subdir of the cloned repository `net-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.
