Tim Boland offers a resource on writing test assertions:
<blockquote>
QASpecGL Good Practice 12 (Write Test Assertions):

http://www.w3.org/QA/Group/2005/05/qaframe-spec/#write-assertion-gp
</blockquote>

Thanks.  The recommended practice reads as follows:
<blockquote>
A test assertion is a measurable or testable statement of behavior,
action, or condition. It is contained within or derived from the
specification's requirements and provides a normative foundation from
which one or more test cases can be built.
</blockquote>


The WCAG Working Group has been working to write success criteria for
each guideline in order to provide the "normative foundation" mentioned
above.

The most recent definition of testability linked from the the page that
Tim pointed us to is as follows:

<blockquote cite="http://esw.w3.org/topic/TestableOrNot">
A proposition is testable if there is such a procedure that assesses the
truth value of a proposition with a high confidence level. Whether the
confidence level is measurable and what confidence level is high enough
depends on the proposition and its framework.
</blockquote>

Our goal is to produce success criteria (test assertions, propositions)
that can be tested for accuracy with a high confidence level.
