Excellent to have unit test cov for these endpoints, @Alopalao.

1 - If you can also refactor e2e test_e2e_40_sdntrace.py, the e2e test cases were using the unversioned endpoints:

tests/test_e2e_40_sdntrace.py
149:                api_url = KYTOS_API + '/amlight/sdntrace/trace'
189:        api_url = KYTOS_API + '/amlight/sdntrace/trace'
236:        api_url = KYTOS_API + '/amlight/sdntrace/trace'
335:        api_url = KYTOS_API + '/amlight/sdntrace/trace'
382:        api_url = KYTOS_API + '/amlight/sdntrace/trace'
822:        api_url = KYTOS_API + '/amlight/sdntrace/trace'
866:        api_url = KYTOS_API + '/amlight/sdntrace/trace'

2 - The exec on scrutinizer there was an unexpected traceback, check it out if it's deterministic or not:

Also, UI client request endpoints need to be updated too (here's one line for example):

LGTM!

This exception in the tests:

It is caused because TestManager class creates a thread which is constantly running. It does not fail in the specified test test_is_entry_invalid_not_colored. Looks like it fails around the time that test is running. Changing the order of tests will change the shown test in this warning.

Nicely done @Alopalao.

Regarding the unit test thread issue, that's a sign that that part isn't easy and graceful to test, so in the future it deserves a refactoring, but it's a not blocker, so map in issue for it, but continue on the other ones that it's on your radar, OK? Thanks

Feel free to merge this and the e2e test PR.
