<h2>Utility Methods</h2>
<p>Four utility methods, <b>Pass()</b>, <b>Fail()</b>, <b>Ignore()</b> and <b>Inconclusive()</b> are provided
in order to allow more direct control of the test process:</p>
<div class="code" style="width: 36em"><pre>
Assert.Pass();
Assert.Pass( string message );
Assert.Pass( string message, object[] parms );
Assert.Fail();
Assert.Fail( string message );
Assert.Fail( string message, object[] parms );
Assert.Ignore();
Assert.Ignore( string message );
Assert.Ignore( string message, object[] parms );
Assert.Inconclusive();
Assert.Inconclusive( string message );
Assert.Inconclusive( string message, object[] parms );</pre>
</div>
<p>The <b>Assert.Pass</b> method allows you to immediately end the test, recording
it as successful. Since it causes an exception to be thrown, it is more
efficient to simply allow the test to return. However, Assert.Pass allows
you to record a message in the test result and may also make the test
easier to read in some situations. Additionally, like the other methods
on this page, it can be invoked from a nested method call with the
result of immediately terminating test execution.</p>
<p>The <b>Assert.Fail</b> method provides you with the ability to generate a failure based
on tests that are not encapsulated by the other methods. It is also useful in
developing your own project-specific assertions.</p>
<p>Here's an example of its use to create a private assertion that tests whether a
string contains an expected value.</p>
<div class="code" style="width: 36em">
<pre>public void AssertStringContains( string expected, string actual )
{
AssertStringContains( expected, actual, string.Empty );
}
public void AssertStringContains( string expected, string actual,
string message )
{
if ( actual.IndexOf( expected ) < 0 )
Assert.Fail( message );
}</pre>
</div>
<p>The <b>Assert.Ignore</b> method provides you with the ability to dynamically cause a
test or suite to be ignored at runtime. It may be called in a test, setup or
fixture setup method. We recommend that you use this only in isolated cases.
The category facility is provided for more extensive inclusion or exclusion of
tests or you may elect to simply divide tests run on different occasions into
different assemblies.</p>
<p>The <b>Assert.Inconclusive</b> method indicates that the test could not be
completed with the data available. It should be used in situations where
another run with different data might run to completion, with either a
success or failure outcome.
