Simple example of a Play Framework / ScalaTest spec using functional composition to keep the building of two similar Requests (only difference is the Request-Method) DRY.

FunctionalComposition.scala

"Delete" taggedAs(tag.RolesTag) in {
  
  val request = (FakeRequest(_:String, "/admin/roles/role-bob")) andThen 
    withAdminCredentials andThen 
    (route(_:FakeRequest[AnyContentAsEmpty.type]))

  for { result <- request(DELETE) } {
    status(result) must equal(SEE_OTHER)
    flash(result).data must contain key("deleted")
  }

  for { result <- request(GET) } {
    status(result) must equal(NOT_FOUND)
  }
}
