Ctrl+C doesn't interrupt tests

KeyboardInterrupt

^C

Consider this: http://zguide.zeromq.org/py:interrupt

Actually it does. But it doesn't happen immediately, graceful interruption is performed instead: current test is completed up to end and then test framework stops. When the tests are started next time they will be started from the next test. Graceful test shutdown is highly important since it's required to clean up environment on 1-3 virtual machines after each test or next tests run wouldn't be possible.

Immediate interruption takes place if user presses Ctrl-C multiple times. In this case no environment cleanup happen and exception is thrown. That was the situation that you have encountered.

It's well described behaviour of python unittest module. Environment changes several times during some tests and allowing to interrupt such tests at any time just makes tests too sophisticated and hard to debug and mantain.

[midenok]

As above picture shows, multiple ^C was pressed and test didn't exit.

[vankoven]

Ok, that wasn't clear from the original issue description. Since you have real issues with starting TempestaFW itself, may be some behaviour on keyboard interrupt signal differs and the framework get stack an some command. It can get stack on unloading Tempesta if it has issues...

The log will be more helpful, if you can reproduce the isue with -vvvvv arguments (level 5 of verbose messages). In this case we will see what cause the freeze.

Just got hang on deproxy start error:

test_basic (tls.test_tls_handshake.Tls12) ...   Init test case...
Running deproxy

    Deproxy: Server: Start on 127.0.0.1:8000.

It seems we hang on proc.join() if deproxy can not start. ERROR message is quite misleading by the way: the TLS test is buggy, but it's quite hard to use deproxy as a separate component due to lack of good error messages.

It becomes annoying to debug new tests with the problem, so I raise priority a little bit.
