Let's look at some of Play's test cases to see how to use the helper methods. For example, consider the DevErrorPageSpec test, which is defined as follows:
object DevErrorPageSpec extends PlaySpecification{
"devError.scala.html" should {
val testExceptionSource = new play.api.PlayException.ExceptionSource("test", "making sure the link shows up") {
...
}
….
"show prod error page in prod mode" in {
val fakeApplication = new FakeApplication() {
override val mode = play.api.Mode.Prod
}
running(fakeApplication) {
val result = DefaultGlobal.onError(FakeRequest(), testExceptionSource)
Helpers.contentAsString(result) must contain("Oops, an error occurred")
}
}
}
}This test starts FakeApplication with the Prod mode and checks the response when FakeRequest encounters an exception.
FakeApplication extends an application and is defined as follows:
case class FakeApplication(config: Map[String, Any] = Map...
