<h3>DatapointAttribute / DatapointsAttribute (NUnit 2.5)</h3>
<p>The <b>Datapoint</b> and <b>Datapoints</b> attributes are used
to provide data for <b>Theories</b> and are ignored for ordinary
tests - including tests with parameters.
<h4>DataPointAttribute</h4>
<p>When a Theory is loaded, NUnit creates arguments for each
of its parameters by using any fields of the same type
as the parameter annotated with the <b>DatapointAttribute</b>.
Fields must be members of the class containing the Theory
and their Type must exactly match the argument for which
data is being supplied.
<h4>DataPointsAttribute</h4>
<p>In addition to specifying individual datapoints, collections of
datapoints may be provided by use of the <b>DatapointsAttribute</b>
- note the spelling. This attribute may be placed on methods or
properties in addition to fields. The returned value must be
either an array of the required type or (beginning with NUnit
2.5.5) an <b>IEnumerable<T></b> returning an enumeration
of the required type. The data Type must exactly match the argument
for which data is being supplied.
<h4>Automatically Supplied Datapoints</h4>
<p>It is normally not necessary to specify datapoints for
<b>boolean</b> or <b>enum</b> arguments. Beginning with
version 2.5.4, NUnit automatically supplies values of <b>true</b>
and <b>false</b> for <b>boolean</b> arguments and will supply all
defined values of any enumeration.
<p>If for some reason you don't wish to use all possible values, you
can override this behavior by supplying your own datapoints. If you
supply any datapoints for an argument, automatic datapoint generation
is suppressed.
<h4>Example</h4>
<p>For an example of use, see <a href="theory.html">TheoryAttribute</a>.
