Example
- Scala
-
def isMethodRejection: Rejection => Boolean = { case MethodRejection(_) => true case _ => false } val route = cancelRejections(isMethodRejection) { post { complete("Result") } } // tests: Get("/") ~> route ~> check { rejections shouldEqual Nil handled shouldEqual false }
- Java
-
final Predicate<Rejection> isMethodRejection = p -> p instanceof MethodRejection; final Route route = cancelRejections( isMethodRejection, () -> post(() -> complete("Result")) ); // tests: runRouteUnSealed(route, HttpRequest.GET("/")) .assertRejections();
