8. def exception(message: String, cause: Option[RuntimeException] = None): RuntimeException

   

   Creates a new instance of exception.

   Creates a new instance of exception. Default implementation uses RequireCore.DefaultExceptionCreator exception creator.

   message

   the message (must be non-blank)

   cause

   the cause exception (must be non-null and not Some(null))

   returns

   new exception instance (non-null)

   Exceptions thrown

   RuntimeException if any argument is not valid

9. def fail(message: ⇒ Any, throwable: Option[RuntimeException] = None): Unit

   

   Fails test.

   Fails test. Must be invoked at every time when requireXXX method fails. Default implementation invokes exception() to create new exception instance with message produced by failureMessage() method and throws the result.

   message

   RequireCore

   Exceptions thrown

   RuntimeException at every invokation

10. def failureMessage[T](message: ⇒ T): String

    

    Constructs the failure message.

    Constructs the failure message. Default implementation invokes toString() method of message and returns result.

    message

    the source message (must be non-null)

    returns

    the failure message (non-null)
