java - Play 2.3.7 when fork in Test = false config options are ignored -

i'm using play 2.3.7 when fork in test := false in build.sbt conf files aren't loaded play when running tests.

the line javaoptions in test += "-dconfig.file=conf/test.conf" in build.sbt should load test.conf when running tests that's not happening.

the workaround run activator , pass above param on command line so:

activator -dconfig.file=conf/test.conf "test-only test.integration.sometest" 

if remove fork in test := false , play finds conf resources - of course can't step through tests sucks.

what missing in build.sbt ? bug in play?

forking tests means run on separate jvm.

not forking tests means run in same jvm sbt , cannot change parameters jvm started after has been started.

the solution if not want fork pass flags jvm sbt runs on when start it, mention in end of question.
