<h3>TestCaseAttribute (NUnit 2.5)</h3>
<p><b>TestCaseAttribute</b> serves the dual purpose of marking a method with
parameters as a test method and providing inline data to be used when
invoking that method. Here is an example of a test being run three
times, with three different sets of data:
<div class="code">
<pre>[TestCase(12,3,4)]
[TestCase(12,2,6)]
[TestCase(12,4,3)]
public void DivideTest(int n, int d, int q)
{
Assert.AreEqual( q, n / d );
}
</pre>
</div>
<p><b>Note:</b> Because arguments to .NET attributes are limited in terms of the
Types that may be used, NUnit will make some attempt to convert the supplied
values using <b>Convert.ChangeType()</b> before supplying it to the test.
<p><b>TestCaseAttribute</b> may appear one or more times on a test method,
which may also carry other attributes providing test data, such as the
<a href="factories.html">FactoriesAttribute</a>.
The method may optionally be marked with the
<a href="test.html">TestAttribute</a> as well.
<p>By using the named parameter <b>Result</b> this test set may be simplified
further:
<div class="code">
<pre>[TestCase(12,3, Result=4)]
[TestCase(12,2, Result=6)]
[TestCase(12,4, Result=3)]
public int DivideTest(int n, int d)
{
return( n / d );
}
</pre>
</div>
<p>In the above example, NUnit checks that the return
value of the method is equal to the expected result provided on the attribut
<p><b>TestCaseAttribute</b> supports a number of additional
named parameters, which may be used as follows:
<dl>
<dt><b>Description</b>
<dd>Sets the description property of the test
<dt><b>ExpectedException</b>
<dd>Specifies a the Type of an exception that should be thrown by this invocation
<dt><b>ExpectedExceptionName</b>
<dd>Specifies a the FullName of an exception that should be thrown by this invocation
<dt><b>ExpectedMessage</b>
<dd>Specifies the message text of the expected exception
<dt><b>MatchType</b>
<dd>A <b>MessageMatch</b> enum value indicating how to test the expected message
(See <a href="exception.html">ExpectedExceptionAttribute</a>)
<dt><b>Result</b>
<dd>The expected result to be returned from the method, which must have
a compatible return type.
<dt><b>TestName</b>
<dd>Provides a name for the test. If not specified, a name is generated based on
the method name and the arguments provided
</dl>
