Assert.Fail

The Assert.Fail 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.

Assert.Fail();
Assert.Fail( string message, params object[] parms );

Here's an example of its use to create a private assertion that tests whether a string contains an expected value.

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 );
}
