tests/gnrc_tcp: provide regression tests for fixed issues #12369

miri64 · 2019-10-03T17:47:07Z

Contribution description

This provides regression tests for some issues that were found in the past. The respective issues are quoted in the comments. I actually already found a regression when implementing these (see #12368).

Testing procedure

BOARD="<pick one>" make -C tests/gnrc_tcp flash
sudo make -C tests/gnrc_tcp test

Issues/PRs references

Require #12368 to work.

miri64 · 2019-10-04T07:43:27Z

@nmeum @brummer-simon please have a look.

brummer-simon

Thanks for providing additional tests to the latest issues.

By looking at the given flake8 config line length up to 119 characters are allowed. Would you please look over the code reformat function calls that are split over multiple lines. It is just easier to read and RIOT deviates from PEP8 in terms of max line length anyway. Aside from that, good job.

tests/gnrc_tcp/tests/05-garbage-pkts.py

brummer-simon

ACK by me.

Aside from code review I tested the PR on 'native'.

EDIT: I'll revert my ACK see next comment.

brummer-simon

I found something small while executing the test on "nucleo-f401re".

tests/gnrc_tcp/tests/05-garbage-pkts.py

brummer-simon · 2019-10-05T11:36:47Z

ACK from my side. Tested here on nucleo-f401re

miri64 · 2019-10-05T13:14:36Z

Rebased to current master to include #12368.

miri64 · 2019-10-05T13:15:27Z

@RIOT-OS/maintainers this also needs a proxy-ACK.

aabadie

Proxy-ACK (also had a look and found no major issues codewise).

You can squash.

miri64 · 2019-10-05T17:26:53Z

@aabadie, so I will squash. Can you maybe also test on samr21-xpro, just to be sure? I didn't have one at hand when working with the tests.

miri64 · 2019-10-06T15:35:17Z

Provided fix for a typo

fjmolinas · 2019-10-06T17:28:57Z

Just following the README and testing on samr21-xpro I have a timeout on gnrc_tcp_open_active:

EDIT: the following output is with echo=true

Just following the README and testing on samr21-xpro I have a timeout on gnrc_tcp_open_active:
sudo -E BOARD=samr21-xpro make -C tests/gnrc_tcp test

This test is not introduced here (the tests here only use gnrc_tcp_open_passive, but I had this occassionally when testing #11930. I hoped the increased timeout would help. In any way: this is unrelated to this PR.

miri64 · 2019-10-06T17:40:19Z

Why is there output in your script btw Oo?

fjmolinas · 2019-10-06T19:41:59Z

Why is there output in your script btw Oo?

I set echo=true to see what was timing ou.

fjmolinas · 2019-10-06T19:45:34Z

This test is not introduced here (the tests here only use gnrc_tcp_open_passive, but I had this occassionally when testing #11930. I hoped the increased timeout would help. In any way: this is unrelated to this PR.

In that case If I limit the test to tests/gnrc_tcp/tests/05-garbage-pkts.py:

sudo -E BOARD=samr21-xpro make -C tests/gnrc_tcp test
make: Entering directory '/home/francisco/Workspace/RIOT/tests/gnrc_tcp'

- test_short_payload SUCCESS

- test_short_header SUCCESS

- test_send_ack_instead_of_syn SUCCESS

- test_option_parsing_term SUCCESS

make: Leaving directory '/home/francisco/Workspace/RIOT/tests/gnrc_tcp'

miri64 · 2019-10-07T04:14:43Z

👍 I'll see if I can reproduce the other test.

miri64 · 2019-10-07T17:12:29Z

(yes I am, but for different cases than @fjmolinas was able to and only in some cases... @brummer-simon I think there is still some stabilization work required to be done to the tests commands...)
