<h2>Summary of Changes in version 4.8</h2>

<h3>Categories</h3>

<p>From a given set of test classes, the <code>Categories</code> runner
runs only the classes and methods
that are annotated with either the category given with the <code>@IncludeCategory</code>
annotation, or a subtype of that category. Either classes or interfaces can be
used as categories. Subtyping works, so if you say <code>@IncludeCategory(SuperClass.class)</code>,
a test marked <code>@Category({SubClass.class})</code> will be run.</p>

<p>You can also exclude categories by using the <code>@ExcludeCategory</code> annotation</p>

<p>Example:</p>

<pre><code>public interface FastTests { /* category marker */ }
public interface SlowTests { /* category marker */ }

public class A {
    @Test
    public void a() {
        fail();
    }

    @Category(SlowTests.class)
    @Test
    public void b() {
    }
}

@Category({SlowTests.class, FastTests.class})
public class B {
    @Test
    public void c() {

    }
}

@RunWith(Categories.class)
@IncludeCategory(SlowTests.class)
@SuiteClasses( { A.class, B.class }) // Note that Categories is a kind of Suite
public class SlowTestSuite {
  // Will run A.b and B.c, but not A.a
}

@RunWith(Categories.class)
@IncludeCategory(SlowTests.class)
@ExcludeCategory(FastTests.class)
@SuiteClasses( { A.class, B.class }) // Note that Categories is a kind of Suite
public class SlowTestSuite {
  // Will run A.b, but not A.a or B.c
}
</code></pre>
