How do you represent a null value in DataWeave?

Explanation:
Representing a null value in DataWeave tests is done with a dedicated helper from the MUnit Tools library: MunitTools::nullValue(). This ensures you produce an actual null value in the DataWeave evaluation, which is important for accurate tests when fields are missing or need to be asserted as null. Using this helper avoids ambiguity where a literal or string like "null" might be misinterpreted, and it matches what the MUnit test framework expects for nulls in assertions. The other options rely on literals or non-existent module paths, which don’t reliably produce a true null in the testing context.
