+  <a name="Intro"></a><div class="header1">About Metacat Testing</div>
+  <a name="Overview"></a><div class="header2">Overview</div>
+  <p>Metacat uses JUnit tests to test its core functionality.  These tests are
+  good for testing the internal workings of an application, but don't test the 
+  layout and appearance.  JUnit tests are meant to be one tool in the developer's 
+  test arsinal. If you are not familiar with JUnit, you should search out some 
+  tutorial documentation online.  One such tutorial is at 
+  <a href="http://clarkware.com/articles/JUnitPrimer.html"> The Clarkware JUnit primer</a></p>
+  
+  <p>Metacat test cases will need to be run on the same server as the Metacat
+  instance that you want to test.  Since Metacat and its test cases share the same
+  configuration files, there is no way to run the tests remotely.</p>
+
+  <a name="MetacatImplementation"></a><div class="header2">JUnit Implementation in Metacat</div>
+  <p>Metacat test cases are located in the code at:
+  <div class="code">&lt;workspace&gt;/metacat/test/edu/ucsb/nceas/metacat*/</div>  
+  There you will find several java files that define JUnit tests.</p>
+  
+  <p> Test cases are run via an ant task, and output from the tests appears in 
+  a build directory.  More on this to follow.</p>
+
+  <a name="WritingTestCase"></a><div class="header1">Writing a Test Case</div>
+  <a name="Basics"></a><div class="header2">Basics</div>
+  <p>All you need to do to get your JUnit test included into the Metacat test 
+  suite is to create it in one of the &lt;workspace&gt;/test/edu/ucsb/nceas/metacat*/
+  directories.  The ant test tasks will know that it should be run. </p>
+  
+  <p> The following methods are required in a test case class:
+  <ul>
+    <li>public &lt;Constructor&gt;(String name) - The constructor for the test class. </li>
+	<li>public void setUp() - Set up any dependencies for the tests.  This is run before each test case.</li> 
+	<li>public void tearDown() - Release an resources used by the test.</li> 
+	<li>public static Test suite() - define the test methods that need to be run.</li>
+	<li>public void initialize() - define any global initializations that need to be done.</li>
+  </ul>
+  
+  You will test for failure using the many assertion methods available.</p>
+  
+  <a name="MCTestCase"></a><div class="header2">MCTestCase Base Class</div>
+  <p>Metacat test cases extend the MCTestCase base class, which holds common 
+  methods and variables.  Some of these include:
+  <ul>
+    <li>SUCCESS/FALURE - boolean variables holding the values for success and failure. </li>
+	<li>metacatUrl, username, password - connection variables used for LDAP connectivity</li> 
+	<li>readDocumentIdWhichEqualsDoc() - method to read a document from Metacat server.</li> 
+	<li>debug() - method to display debug output to standard error.</li>
+  </ul>
+  These are just a few examples to give you an idea of what is in MCTestCase.
+  </p>
+  
+  <a name="BestPractices"></a><div class="header2">Best Practices</div>
+  <p>The following are a few best practices when writing test cases:
+  <ul>
+    <li>Extend MCTestCase - Although strictly speaking, it is possible to bypass MCTestCase
+    and just extend the JUnit TestCase class, you should not do so.   You should always
+    extend the MCTestCase class.</li>
+    <li>Extend Multiple Test Methods - Try to strike a balance between the number of test 
+    methods and the size of each test.  If a test method starts to get huge, you might see
+    if you can break it down into mulitple tests based on functionality.  If the number of
+    tests in the test suite starts to get large, you might see if it makes sense to 
+    separate them out into different test classes.</li>
+	<li>Use assertion message - Most assertion methods have an alternate implementation that 
+	includes a message parameter.  This message will be shown if the assertion fails.  You
+	should use this version of the assertion method.</li> 
+	<li>debug() - You should use the debug() method available in the MCTestCase class to
+	display debug output as opposed to System.err.println().  The test configuration will
+	allow you to turn off debug output when you use the debug() method.</li>
+  </ul>
+
+  <a name="RunTests"></a><div class="header1">Running Test Cases</div>
+  <a name="AntTask"></a><div class="header2">Ant task</div>
+  <p>As we discussed earlier, the test cases run from within ant tasks.  There is a 
+  task to run all tests and a task to run individual tests. </p>
+  <p>You will need to have ant installed on your system.  For downloads and instructions,
+  visit the <a href="http://ant.apache.org/">Apache Ant site</a>.
+  </p>
+  <a name="ConfigureMetacat"></a><div class="header2">Configure Metacat For Testing</div>
+  <p>The test cases will look at the server's metacat properties file for configuration, 
+  so there are two places that need to be configured.</p>
+  <p>First, you need to edit the configuration file at:
+  <div class="code">&lt;workspace&gt;/metacat/test/test.properties</div>
+  This should only hold one property: metacat.contextDir.  This should point to 
+  the context directory for the metacat server you are testing.  For example:
+  <div class="code">metacat.contextDir=/usr/share/tomcat5.5/webapps/knb</div>
+  The test classes will use this to determine where to look for the server
+  metacat.properties file.</p>
+  
+  <p>the remainder of the configuration needs to happen in the actual server's 
+  metacat.properties file located at:
+  <div class="code">&lt;workspace&gt;/metacat/lib/metacat.properties</div>
+  You will need to verify that all test.* properties are set correctly:
+  <ul>
+    <li>test.printdebug - true if you want debug output, false otherwise </li>
+    <li>test.metacatUrl - the url for the metacat servlet (i.e. http://localhost:8080/knb/metacat)</li>
+    <li>test.contextUrl - the url for the metacat web service (i.e. http://localhost:8080/knb)</li>
+    <li>test.metacatDeployDir - the directory where metacat is physically deployed (i.e. /usr/local/tomcat/webapps/knb)</li>
+    <li>test.mcUser - the first metacat test user ("uid=kepler,o=unaffiliated,dc=ecoinformatics,dc=org" should be fine)</li>
+    <li>test.mcPassword - the first metacat test password ("kepler" should be fine)</li>
+    <li>test.mcAnotherUser - the second metacat test user.  This user must be a member of the knb-usr 
+        group in ldap. ("uid=test,o=NCEAS,dc=ecoinformatics,dc=org" should be fine)</li>
+    <li>test.mcAnotherPassword - the second metacat test password ("test" should be fine)</li>
+    <li>test.piscoUser - the pisco test user ("uid=piscotest,o=PISCO,dc=ecoinformatics,dc=org" should be fine)</li>
+    <li>test.piscoPassword - the pisco test password ("testPW" should be fine)</li>
+    <li>test.lterUser - the lter test user ("uid=tmonkey,o=LTER,dc=ecoinformatics,dc=org" should be fine)</li>
+    <li>test.lterPassword - the lter test password ("T3$tusr" should be fine)</li>
+    <li>test.testProperty - a property to verify that we can read properties (leave as "testing")</li>
+  </ul>
+  </p>
+  
+  <p>Note that none of the test users should also be administrative users.  This will mess up 
+  the access tests since some document modifications will succeed when we expect them to fail.</p>
+  
+  <p>Once this is done, you will need to rebuild and redeploy the Metacat server.  Note that
+  changing these properties does nothing to change the way the Metacat server runs.  Rebuilding
+  and redeploying merely makes the test properties available to the JUnit tests.</p>
+  
+  <a name="RunAllTests"></a><div class="header2">Run All Tests</div>
+  <p>To run all tests, go to the &lt;workspace&gt;/metacat directory and type</p>
+  <div class="code">ant clean test</div>
+  You will see a line to standard output summarizing each test result.
+  </p>
+  
+  <a name="RunOneTest"></a><div class="header2">Run One Test</div>
+  <p>To run one test, go to the &lt;workspace&gt;/metacat directory and type</p>
+  <div class="code">ant clean runonetest -Dtesttorun=&lt;test_name&gt;</div>
+  Where &lt;test_name&gt; is the name of the JUnit test class (without .java on 
+  the end).  You will see debug information print to standard error.
+  </p>
+  
+  <a name="ViewingOutput"></a><div class="header2">Viewing Test Output</div>
+  <p>Regardless of whether you ran one test or all tests, you will see output in
+  the Metacat build directory in your code at:
+  <div class="code">&lt;workspace&gt;/metacat/build</div>
+  There will be one output file for each test class.  The files will look like 
+  <div class="code">TEST-edu.ucsb.nceas.&lt;test_dir&gt;.&lt;test_name&gt;.txt</div>
+  where &lt;test_dir&gt; is the metacat* directory where the test lives and 
+  &lt;test_name&gt; is the name of the JUnit test class. These output files will have
+  all standard error and standard out output as well as information on assertion 
+  failures in the event of a failed test.
