The scala test code:
import play.api.test._
import scala._
import org.specs2.execute.Result
object ThrowTest extends PlaySpecification {
"throwA" should {
"catch the exception test1" in {
world must throwA[Exception]
}
"catch the exception test2" in {
hello {
world =>
world must throwA[Exception]
}
}
}
def hello(action: (String) => Result) = {
action(world)
}
def world: String = {
throw new Exception("world-exception")
}
}
Why test1
is working as I expected, but test2
is not, which throws the exception to outer and never catch it:
[info] ! catch the exception test2
[error] Exception: world-exception (ThrowTest.scala:26)
[error] database.ThrowTest$.world(ThrowTest.scala:26)
[error] database.ThrowTest$.hello(ThrowTest.scala:22)
[error] database.ThrowTest$$anonfun$1$$anonfun$apply$4.apply(ThrowTest.scala:14)
[error] database.ThrowTest$$anonfun$1$$anonfun$apply$4.apply(ThrowTest.scala:14)
[info] Total for specification ThrowTest
Because for test 2 your exception is thrown from
hello
before callingaction
.action
is aString => Result
and you call it withworld
which - when evaluated - throws an exception, therefor, all this code:is never executed.
