# `gnrc_ipv6_ext` test
|
|
|
|
|
|
|
|
|
|
This test utilizes [scapy] to test the GNRC's RPL source routing header
|
|
|
|
|
handling.
|
|
|
|
|
|
|
|
|
|
To test, compile and flash the application to any board of your liking (since
|
|
|
|
|
`ethos` is used to communicate with non-native boards it really doesn't matter
|
|
|
|
|
as long as the application fits).
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
make flash
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
And run the tests using
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
sudo make test
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Note that root privileges are required since `scapy` needs to construct Ethernet
|
|
|
|
|
frames to properly communicate over the TAP interface.
|
|
|
|
|
|
|
|
|
|
The tests succeeds if you see the string `SUCCESS`.

|
|
|
If any problems are encountered (i.e. if the test prints the string `FAILED`),
|
2018-11-13 19:10:29 +01:00
|
|
|
set the echo parameter in the `run()` function at the bottom of the test script
|
|
|
|
|
(tests/01-run.py) to `True`. The test script will then offer a more detailed
|
|
|
|
|
output.
|
|
|
|
|
|
|
|
|
|
It might be that due to `scapy`'s sniffer not picking up an expected packet
|
|
|
|
|
sometimes that the test application hangs for a while and then issues `FAILED`.
|
|
|
|
|
Just restart the test in that case.
