> In developing a test case that uses MetricsAsserts, I had two issues:
> 1) the error output in the case that an assertion failed does not currently give any
information as to the _actual_ value of the metric
> 2) there is no way to retrieve the metric variable (eg to assert that the sum of a metric
over all DNs is equal to some value)
> This JIRA is to improve this test class to fix the above issues.
