How do I specify a config file with sbt 0.12.2 for sbt test?

Question

I have a Play! project with unit tests and I am trying to run tests on my staging environment using sbt. Before I upgraded to Play 2.1, when I was using Play 2.0.4 and sbt 0

Answer 1

test is using forked jvm. Use javaOptions sbt setting to pass jvm options to it e.g.

javaOptions ++= Seq("-Dconfig.file=conf/staging.conf")
or

javaOptions ++= collection.JavaConversions.propertiesAsScalaMap(System.getProperties).map{ case (key,value) => "-D" + key + "=" +value }.toSeq

Answer 2

Similar approach is to just pass the config file to use, while triggering the sbt test

First, in the Build.scala file

val testOptions = "-Dconfig.file=conf/" + Option(System.getProperty("test.config")).getOrElse("application") + ".conf"

val main = PlayProject(appName, appVersion, appDependencies, mainLang = SCALA).settings(
    javaOptions in Test += testOptions
)

Then, in the command line to run the test with integ.conf

sbt -Dtest.config=integ test

to use the default application.conf

sbt test
