<title>JUnitReport Task</title>

<body>

<h2 id="junitreport">JUnitReport</h2>
<h3>Description</h3>
<p>Merge the individual XML files generated by the <code>JUnit</code> task and eventually apply a
stylesheet on the resulting merged document to provide a browsable report of the testcases
results.</p>

<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="https://xml.apache.org/xalan-j/" target="_top">Xalan 2.4.1+ or
Xalan XSLTC</a> (JDK 1.4 contains a version of Xalan 2.x, while JDK 1.5 ships with a version of
XSLTC). JDK 1.4.2-01 and later ships with a bundled Xalan 2.4.1+, meaning that JDKs prior to version
1.4.2-01 won't work out of the box. The table below summarize the compatibility status.</p>
<table>
<tr><th scope="col">Xalan</th><th scope="col">Sun JDK Bundle</th><th scope="col">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><em><u>Deprecated</u>,
use <samp>${ant.home}/etc/junit-frames-xalan1.xsl</samp><br/>Upgrade Xalan using the JDK endorsement
mechanism</em></td></tr>
</table>

<p>In Ant 1.6.2, we had to decide between supporting Xalan 1/Xalan 2.4.1- and Xalan 2.4.1+/XSLTC,
because there was no way to support both couples at the same time.</p>
<p><em>Since Ant 1.7</em>, we dropped support for Xalan 1, because Xalan 1 was not available anymore
for quite some time.</p>

<h3>Parameters</h3>
<table class="attr">
  <tr>
    <th scope="col">Attribute</th>
    <th scope="col">Description</th>
    <th scope="col">Required</th>
  </tr>
  <tr>
    <td>tofile</td>
    <td>The name of the XML file that will aggregate all individual XML testsuites previously
      generated by the <code>JUnit</code> task.</td>
    <td>No; defaults to <samp>TESTS-TestSuites.xml</samp></td>
  </tr>
  <tr>
    <td>todir</td>
    <td>The directory where the file resulting from the individual XML testsuite aggregation should
      be written.</td>
    <td>No; defaults to current directory</td>
  </tr>
</table>
<h3 id="nested">Parameters specified as nested elements</h3>
<h4>fileset</h4>
<p><code>junitreport</code> collects individual xml files generated by the <code>JUnit</code> 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 class="attr">
  <tr>
    <th scope="col">Attribute</th>
    <th scope="col">Description</th>
    <th scope="col">Required</th>
  </tr>
  <tr>
    <td>format</td>
    <td>The format of the generated report. Must be either <q>noframes</q> or <q>frames</q>.</td>
    <td>No; defaults to <q>frames</q></td>
  </tr>
  <tr>
    <td>styledir</td>
    <td>The directory where the stylesheets are defined. They must be conforming to the following
      conventions:
      <ul>
        <li><q>frames</q> format: the stylesheet must be named <samp>junit-frames.xsl</samp>,
          or <samp>junit-frames-saxon.xsl</samp> if you are using Saxon 9+.</li>
        <li><q>noframes</q> format: the stylesheet must be named <samp>junit-noframes.xsl</samp>,
          or <samp>junit-noframes-saxon.xsl</samp> if you are using Saxon 9+.</li>
      </ul>
    </td>
    <td>No; defaults to embedded stylesheets</td>
  </tr>
  <tr>
    <td>todir</td>
    <td>The directory where the files resulting from the transformation should be written to.</td>
    <td>No; defaults to current directory</td>
  </tr>
</table>
<p>Ant assumes the following concerning the <q>frames</q> and <q>noframes</q> formats:</p>
<ul>
  <li>The <q>frames</q> format uses a stylesheet which is generating output <em>only</em> by
    redirecting.</li>
  <li>The <q>noframes</q> format does not use redirecting and generates one file
    called <samp>junit-noframes.html</samp>.</li>
</ul>
<p>Custom versions of <samp>junit-frames.xsl</samp> or <samp>junit-noframes.xsl</samp> must adhere
to the above conventions.</p>

<h3>Nested element of the report tag</h3>
<h4>param</h4>
<p><em>Since Ant 1.7</em>, the <var>report</var> tag supports nested <code>param</code> tags.  These
tags can pass XSL parameters to the stylesheet.</p>
<h3>Parameters</h3>
<table class="attr">
  <tr>
    <th scope="col">Attribute</th>
    <th scope="col">Description</th>
    <th scope="col">Required</th>
  </tr>
  <tr>
    <td>name</td>
    <td>Name of the XSL parameter</td>
    <td>Yes</td>
  </tr>
  <tr>
    <td>expression</td>
    <td>Text value to be placed into the <code>param</code>.<br/>Was originally intended to be an
      XSL expression.</td>
    <td>Yes</td>
  </tr>
  <tr>
    <td>if</td>
    <td>The <code>param</code> will only be passed <a href="../properties.html#if+unless">if this
      property is set</a>.</td>
    <td>No</td>
  </tr>
  <tr>
    <td>unless</td>
    <td>The <code>param</code> will not be passed <a href="../properties.html#if+unless">if this
      property is set</a>.</td>
    <td>No</td>
  </tr>
</table>

<p>The built-in stylesheets support the following parameters:</p>
<table>
  <tr>
    <th scope="col">XSL Parameter</th>
    <th scope="col">Description</th>
    <th scope="col">Required</th>
  </tr>
  <tr>
    <td>TITLE</td>
    <td>Title used in <code>&lt;title&gt;</code> and <code>&lt;h1&gt;</code> tags</td>
    <td>No; defaults to <q>Unit Test Results</q></td>
  </tr>
</table>

<h4>classpath</h4>
<p><em>Since Ant 1.9.5</em>. Like for the <a href="../Tasks/style.html#classpath">XSLT task</a>, a
nested <code>&lt;classpath&gt;</code> will be used to load the processor.</p>

<h4>factory</h4>
<p><em>Since Ant 1.9.5</em>. Like for the <a href="../Tasks/style.html#factory">XSLT task</a>, a
nested <code>&lt;factory&gt;</code> can be used to specify factory settings.</p>

<h3>Examples</h3>

<p>Generate a <samp>TESTS-TestSuites.xml</samp> file in the directory <samp>reports</samp> and
generate the default framed report in the directory <samp>report/html</samp>.</p>

<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>

<p>This example requires a file called <samp>junitreport/junit-frames.xsl</samp>. The XSL
parameters <q>key1</q> and <q>key2</q> will be passed to the XSL transformation.</p>

<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>
