Must Not Contain rules are specified just like Must Contain rules, however they are interpreted as rows that must not appear in the Result Set. The “Ordered Match” and “Exact Match” flags do not apply to Must Not Contain Rules, because any Must Not Contain rule simply specifies a row that cannot appear anywhere within the Result Set.

As with Must Contain rules, any blank cell is treated as a “Don’t Care” value, meaning if all the non-blank cells in a row of the Must Not Contain rules matches any row in the Primary Results Set, the test fails. Variables are also allowed in the cells of a Must Not Contain rule.
