<h2>Comparison Constraints (NUnit 2.4 / 2.5)</h2>
|
|
|
|
<p>Comparison constraints are able to test whether one value
|
|
is greater or less than another. Comparison constraints work
|
|
on numeric values, as well as other objects that implement the
|
|
<b>IComparable</b> interface or - beginning with NUnit 2.5 -
|
|
<b>IComparable<T></b>.
|
|
|
|
<p>Beginning with NUnit 2.5, you may supply your own comparison
|
|
algorithm through the <b>Using</b> modifier.
