025 * Enum AssertionLevel designates the level of a given {@link Assertion} instance. This is used in conjunction with the
026 * {@link cascading.flow.FlowConnector} to plan assertions out of a particular {@link cascading.flow.Flow} instance.
027 * <p>
028 * Currently Assertions can be denote either VALID or STRICT.
029 * <p>
030 * VALID assertions are used to validate data during staging testing or for use in a production environment.
031 * <p>
032 * STRICT assertions should be used as unit test would be against regression data and during development.
