Activating logging in test mode in Play 2.0.x
Because of a permgen leak related to third-party libraries, the logging in test mode is disabled in Play 2.0.x (there’s a fix coming up in Play 2.1). In some cases, seeing what happens while running a test can be useful - e.g. when debugging calls to various Akka actors that don’t quite behave as expected.
Luckily there’s a workaround, which is to specify a logger for logback by hand when starting play or SBT:
does the trick.
