<P>
<p>The <code>Test</code> annotation tells JUnit that the <code>public void</code> method
to which it is attached can be run as a test case. To run the method,
JUnit first constructs a fresh instance of the class then invokes the
annotated method. Any exceptions thrown by the test will be reported
by JUnit as a failure. If no exceptions are thrown, the test is assumed
to have succeeded.</p>
<p>A simple test looks like this:
<pre>
public class Example {
<b>@Test</b>
public void method() {
org.junit.Assert.assertTrue( new ArrayList().isEmpty() );
}
}
</pre>
</p>
<p>The <code>Test</code> annotation supports two optional parameters.
The first, <code>expected</code>, declares that a test method should throw
an exception. If it doesn't throw an exception or if it throws a different exception
than the one declared, the test fails. For example, the following test succeeds:
<pre>
@Test(<b>expected=IndexOutOfBoundsException.class</b>) public void outOfBounds() {
new ArrayList<Object>().get(1);
}
</pre></p>
<p>The second optional parameter, <code>timeout</code>, causes a test to fail if it takes
longer than a specified amount of clock time (measured in milliseconds). The following test fails:
<pre>
@Test(<b>timeout=100</b>) public void infinity() {
while(true);
}
</pre></p>
