[2.0.x] Enabling logging in test mode for low-level Akka debugging

[Manuel Bernhardt]

Hi,

well, the subject says it all. I'd like to see exactly what's going on
with the messages that are flying around for a specific test case, but
Play eats all logging in test mode. Is there perhaps a way around it?

logging in test mode is disabled now because we ran into permgen issues (partly caused by logback).

We will re-enable it for 2.1 once https://github.com/harrah/xsbt/issues/565 is released and we can turn back on "fork in Test := true". That should address this problem.

HTH,

Peter

Hi,

thanks Peter, I know about the permgen issue. Nonetheless in some
cases it would be extremely convenient to see the logs in test mode.
Debugging through Akka internals when there's many actors involved is
not very fun, I'd very much prefer giving the JVM 4 GB of permgen just
to see the logs. Could this behavior not be made an configuration
option, regardless of the permgen issue being resolved or not (it
could even print a big warning on test start)?

Thanks,

Manuel

Actually just a pointer to where the logging get disabled in 2.x would
already help me a lot. I can't seem to figure out where the logs are
turned off in test mode.

Thanks,

Nevermind, I just found it.

Hooray, there's a workaround: just starting Play by specifying a
logger (-Dlogger.resource=test-logger.xml) seems to do the trick.

What format is the test-logger.xml in? Log4j? I don't know what logging system is running under play but this workaround is essential for me.

Honestly, I wouldn't care either if I got perm gen after some testing, but the logs are vital. Actually, having some feedback about which assertion failed (stacktrace) would be great too. I miss the JUnit report XML as well. I suspect the latter one does not require logging to be enabled.

Let's hope SBT will be fixed soon.

Thanks,

Andras

test-logger.xml is a logback logger. See the documentation here:
