+    <para>For complex batch jobs, test cases in the end-to-end tesing approach
+    may become unmanageable. It these cases, it may be more useful to have
+    test cases to test individual steps on their own. The
+    <classname>AbstractJobTests</classname> class contains a method
+    <methodname>launchStep</methodname> that takes a step name and runs just
+    that particular <classname>Step</classname>. This approach allows for more
+    targeted tests by allowing the test to set up data for just that step and
+    to validate its results directly.</para>
