Play 2.1.1 writes the test reports to target/test-reports.
For Java no further configuration is necessary, but for Scala adjust your project/Build.scala:
import sbt._
import Keys._
import play.Project._
object ApplicationBuild extends Build {
val appName = "so-scala"
val appVersion = "1.0-SNAPSHOT"
val appDependencies = Seq(
// Add your project dependencies here,
jdbc,
anorm
)
val main = play.Project(appName, appVersion, appDependencies).settings(
//write test reports and to console
testOptions in Test += Tests.Argument("junitxml", "console")
)
}
