org.scalactic.exceptions

Exception that indicates a passed argument was null.

Prior to ScalaTest and Scalactic 3.0.0, a null argument (where non-null was required) would result in a NullPointerException. Although throwing NullPointerException is the tradition in Java APIs, Scala.js does not support a NullPointerException. To make the behavior the same on both the JVM and Scala.js, the change to throwing NullArgumentException was made throughout the ScalaTest and Scalactic, including the requireNonNull method of trait <code>Requirements</code>.

Exception that indicates a validation failed.

This exception is used to indicate and describe a failed validation by the validating methods of <code>TrySugar</code> and <code>FutureSugar</code>.
