024 * Enum AssertionLevel designates the level of a given {@link Assertion} instance. This is used in conjunction with the

027 * Currently Assertions can be denote either VALID or STRICT.

029 * VALID assertions are used to validate data during staging testing or for use in a production environment.

031 * STRICT assertions should be used as unit test would be against regression data and during development.
