      <question>What is a Mojo Testing Harness?</question>
      <answer>
        <p>
          A unit test attempts to verify a mojo as an isolated unit, by mocking out the rest of the Maven environment.
          A mojo unit test does not attempt to run your plugin in the context of a real Maven build.
          Unit tests are designed to be fast.
        </p>
        <p>
          This testing library is <b>NOT</b> designed for integration or functional testing.

      <question>What kind of unit tests are supported?</question>
      <answer>
        <p>
          <dl>
            <dt>TestCase from JUnit</dt>
            <dd>You could use the <a href="http://junit.org/">JUnit framework</a> to test your plugin in
              the same way you'd write any other JUnit test cases, i.e. by writing a test class which extends
              <i>TestCase</i>.</dd>
            <dt>TestCase from Plexus</dt>
            <dd>Mojos are written to take specific advantage of the <a href="http://plexus.codehaus.org/">Plexus</a>
              container. If you need Plexus container services, you could write your class which extends <i>PlexusTestCase</i>,
              instead of <i>TestCase</i>.</dd>
            <dt>TestCase from Testing Harness</dt>
            <dd>If you need to inject Maven objects into your mojo, you could use the <i>maven-plugin-testing-harness</i>.
              The <i>maven-plugin-testing-harness</i> is explicitly intended to test the
              <i>org.apache.maven.reporting.AbstractMavenReport#execute()</i> implementation.</dd>
