| 27 | <h2>Utility Methods</h2>
|
|---|
| 28 | <p>Four utility methods, <b>Pass()</b>, <b>Fail()</b>, <b>Ignore()</b> and <b>Inconclusive()</b> are provided
|
|---|
| 29 | in order to allow more direct control of the test process:</p>
|
|---|
| 30 | <div class="code" style="width: 36em"><pre>
|
|---|
| 31 | Assert.Pass();
|
|---|
| 32 | Assert.Pass( string message );
|
|---|
| 33 | Assert.Pass( string message, object[] parms );
|
|---|
| 34 |
|
|---|
| 35 | Assert.Fail();
|
|---|
| 36 | Assert.Fail( string message );
|
|---|
| 37 | Assert.Fail( string message, object[] parms );
|
|---|
| 38 |
|
|---|
| 39 | Assert.Ignore();
|
|---|
| 40 | Assert.Ignore( string message );
|
|---|
| 41 | Assert.Ignore( string message, object[] parms );
|
|---|
| 42 |
|
|---|
| 43 | Assert.Inconclusive();
|
|---|
| 44 | Assert.Inconclusive( string message );
|
|---|
| 45 | Assert.Inconclusive( string message, object[] parms );</pre>
|
|---|
| 46 | </div>
|
|---|
| 47 | <p>The <b>Assert.Pass</b> method allows you to immediately end the test, recording
|
|---|
| 48 | it as successful. Since it causes an exception to be thrown, it is more
|
|---|
| 49 | efficient to simply allow the test to return. However, Assert.Pass allows
|
|---|
| 50 | you to record a message in the test result and may also make the test
|
|---|
| 51 | easier to read in some situations. Additionally, like the other methods
|
|---|
| 52 | on this page, it can be invoked from a nested method call with the
|
|---|
| 53 | result of immediately terminating test execution.</p>
|
|---|
| 54 | <p>The <b>Assert.Fail</b> method provides you with the ability to generate a failure based
|
|---|
| 55 | on tests that are not encapsulated by the other methods. It is also useful in
|
|---|
| 56 | developing your own project-specific assertions.</p>
|
|---|
| 57 | <p>Here's an example of its use to create a private assertion that tests whether a
|
|---|
| 58 | string contains an expected value.</p>
|
|---|
| 59 | <div class="code" style="width: 36em">
|
|---|
| 60 | <pre>public void AssertStringContains( string expected, string actual )
|
|---|
| 61 | {
|
|---|
| 62 | AssertStringContains( expected, actual, string.Empty );
|
|---|
| 63 | }
|
|---|
| 64 |
|
|---|
| 65 | public void AssertStringContains( string expected, string actual,
|
|---|
| 66 | string message )
|
|---|
| 67 | {
|
|---|
| 68 | if ( actual.IndexOf( expected ) < 0 )
|
|---|
| 69 | Assert.Fail( message );
|
|---|
| 70 | }</pre>
|
|---|
| 71 | </div>
|
|---|
| 72 | <p>The <b>Assert.Ignore</b> method provides you with the ability to dynamically cause a
|
|---|
| 73 | test or suite to be ignored at runtime. It may be called in a test, setup or
|
|---|
| 74 | fixture setup method. We recommend that you use this only in isolated cases.
|
|---|
| 75 | The category facility is provided for more extensive inclusion or exclusion of
|
|---|
| 76 | tests or you may elect to simply divide tests run on different occasions into
|
|---|
| 77 | different assemblies.</p>
|
|---|
| 78 | <p>The <b>Assert.Inconclusive</b> method indicates that the test could not be
|
|---|
| 79 | completed with the data available. It should be used in situations where
|
|---|
| 80 | another run with different data might run to completion, with either a
|
|---|
| 81 | success or failure outcome.
