<title>JUnitReport Task</title>

<body>

<h2><a name="junitreport">JUnitReport</a></h2>
Merge the individual XML files generated by the JUnit task and eventually apply
a stylesheet on the resulting merged document to provide a browsable report of
the testcases results.
<p><strong>Note:</strong> This task depends on external libraries not included in
the Apache Ant distribution.  See <a href="../install.html#librarydependencies">
Library Dependencies</a> for more information.</p>

<h3>Requirements</h3>

<p>The task needs Apache <a
href="http://xml.apache.org/xalan-j/">Xalan 2.4.1+ or Xalan XSLTC</a>
(JDK 1.4 contains a version of Xalan-J 2.x while JDK 1.5 ships with a
version of XSLTC). Starting from JDK 1.4.2-01 it ships with a bundled
Xalan-J 2.4.1+, meaning that JDK version prior to 1.4.2-01 won't work
out of the box. The table below summarize the compatibility status. 
</p>
<table border="1" cellpadding="2" cellspacing="0">
<tr><th>Xalan</th><th>Sun JDK Bundle</th><th>Status<th></tr> 
<tr><td>2.4.1+</td><td>JDK 1.4.2-01+</td><td>OK</td></tr>
<tr><td>XSLTC</td><td>JDK 1.5.x</td><td>OK</td></tr>
<tr><td>2.x</td><td>JDK 1.4.x</td><td>DEPRECATED<br><i>Use ${ant.home}/etc/junit-frames-xalan1.xsl
<br> Upgrade Xalan using the JDK endorsement mechanism</i></td></tr>
</table>

<p>With Ant 1.6.2 we had to decide between supporting Xalan-J 1/Xalan J 2.4.1-
and Xalan 2.4.1+/XSLTC, since there was no way to support both couples at the same
time.</p>
<p>With Ant 1.7 we had to drop support Xalan-J 1, since Xalan-J 1 has not 
available anymore for quite some time.</p>

<h3>Parameters</h3>
<table border="1" cellpadding="2" cellspacing="0">
  <tr>
    <td width="12%" valign="top"><b>Attribute</b></td>
    <td width="78%" valign="top"><b>Description</b></td>
    <td width="10%" valign="top"><b>Required</b></td>
  </tr>
  <tr>
    <td valign="top">tofile</td>
    <td valign="top">The name of the XML file that will aggregate all individual
      XML testsuite previously generated by the JUnit task.</td>
    <td align="center" valign="top">No. Default to TESTS-TestSuites.xml</td>
  </tr>
  <tr>
    <td valign="top">todir</td>
    <td valign="top">The directory where should be written the file resulting
      from the individual XML testsuite aggregation.</td>
    <td align="center" valign="top">No. Default to current directory</td>
  </tr>
</table>
<h3><a name="nested">Nested Elements</a></h3>
<h4>fileset</h4>
<p><code>junitreport</code> collects individual xml files generated by the JUnit
task using the nested <a href="../Types/fileset.html"><code>&lt;FileSet&gt;</code></a>
element.</p>
<h4>report</h4>
<p>Generate a browsable report based on the document created by the merge.</p>
<h3>Parameters</h3>
<table border="1" cellpadding="2" cellspacing="0">
  <tr>
    <td width="12%" valign="top"><b>Attribute</b></td>
    <td width="78%" valign="top"><b>Description</b></td>
    <td width="10%" valign="top"><b>Required</b></td>
  </tr>
  <tr>
    <td valign="top">format</td>
    <td valign="top">The format of the generated report. Must be &quot;noframes&quot;
      or &quot;frames&quot;.</td>
    <td align="center" valign="top">No, default to &quot;frames&quot;</td>
  </tr>
  <tr>
    <td valign="top">styledir</td>
    <td valign="top">The directory where the stylesheets are defined. They must
      be conforming to the following conventions:
      <ul>
        <li>frames format: the stylesheet must be named <i>junit-frames.xsl</i>.</li>
        <li>noframes format: the stylesheet must be named <i>junit-noframes.xsl</i>.</li>
      </ul>
    </td>
    <td align="center" valign="top">No. Default to embedded stylesheets.</td>
  </tr>
  <tr>
    <td valign="top">todir</td>
    <td valign="top">The directory where the files resulting from the
      transformation should be written to.</td>
    <td align="center" valign="top">No. Default to current directory</td>
  </tr>
</table>
<p> Ant assumes the following concerning the <tt>frames</tt> and <tt>noframes</tt> formats :</p>
<p>The <tt>frames</tt> format uses
a stylesheet which is generating output <em>only</em> by redirecting.</p>
<p>The
<tt>noframes</tt> format does not use redirecting and generates one
file called <tt>junit-noframes.html</tt>.</p>
<p>Custom versions of <tt>junit-frames.xsl</tt> or <tt>junit-noframes.xsl</tt> must adhere to the above conventions.</p>

<h3>Nested Element of the report tag</h3>
<h4>param</h4>
<em>Since Ant 1.7</em>the report tag supports nested param tags.
These tags can pass XSL parameters to the stylesheet.
<h3>Parameters</h3>
<table width="60%" border="1" cellpadding="2" cellspacing="0">
  <tr>
    <td valign="top"><b>Attribute</b></td>
    <td valign="top"><b>Description</b></td>
    <td align="center" valign="top"><b>Required</b></td>
  </tr>
  <tr>
    <td valign="top">name</td>
    <td valign="top">Name of the XSL parameter</td>
    <td align="center" valign="top">Yes</td>
  </tr>
  <tr>
    <td valign="top">expression</td>
    <td valign="top">Text value to be placed into the param.<br>
    Was originally intended to be an XSL expression.</td>
    <td align="center" valign="top">Yes</td>
  </tr>
  <tr>
    <td valign="top">if</td>
    <td valign="top">The param will only be passed <a href="../properties.html#if+unless">if this property is set</a>.</td>
    <td align="center" valign="top">No</td>
  </tr>
  <tr>
    <td valign="top">unless</td>
    <td valign="top">The param will not be passed <a href="../properties.html#if+unless">if this property is set</a>.</td>
    <td align="center" valign="top">No</td>
  </tr>
</table>

<p>The built-in stylesheets support the following parameters:</p>
<table width="60%" border="1" cellpadding="2" cellspacing="0">
  <tr>
    <td valign="top"><b>XSL-Parameter</b></td>
    <td valign="top"><b>Description</b></td>
    <td align="center" valign="top"><b>Required</b></td>
  </tr>
  <tr>
    <td valign="top">TITLE</td>
    <td valign="top">Title used in &lt;title&gt; and &lt;h1&gt; tags</td>
    <td align="center" valign="top">No. Defaults to <i>Unit Test Results.</i></td>

<h3>Example of report</h3>
<blockquote>
  <pre>&lt;junitreport todir=&quot;./reports&quot;&gt;
  &lt;fileset dir=&quot;./reports&quot;&gt;
    &lt;include name=&quot;TEST-*.xml&quot;/&gt;
  &lt;/fileset&gt;
  &lt;report format=&quot;frames&quot; todir=&quot;./report/html&quot;/&gt;
&lt;/junitreport&gt;
</pre>
</blockquote>
<p>would generate a <tt>TESTS-TestSuites.xml</tt> file in the directory <tt>reports</tt> and
generate the default framed report in the directory <tt>report/html</tt>.</p>
<h3>Example of report with xsl params</h3>
<blockquote>
  <pre>
&lt;junitreport todir="${outputdir}"&gt;
    &lt;fileset dir="${jrdir}"&gt;
        &lt;include name="TEST-*.xml"/&gt;
    &lt;/fileset&gt;
    &lt;report todir="${outputdir}/html"
        styledir="junitreport"
        format="frames"&gt;
        &lt;param name="key1" expression="value1"/&gt;
        &lt;param name="key2" expression="value2"/&gt;
    &lt;/report&gt;
&lt;/junitreport&gt;
  </pre>
  </blockquote>
<p>This example requires a file called <tt>junitreport/junit-frames.xsl</tt>.
    The XSL parameters key1 and key2 will be passed to the XSL transformation.</p>
