## JUnitReport

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.

Note: This task depends on external libraries not included in the Ant distribution. See Library Dependencies for more information.

### Requirements

The task needs Apache Xalan 2.4.1+ or Xalan XSLTC (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.

Xalan | Sun JDK Bundle | Status |
--- | --- | --- | ---
2.4.1+ | JDK 1.4.2-01+ | OK
XSLTC | JDK 1.5.x | OK
2.x | JDK 1.4.x | DEPRECATED Use /Users/antoine/dev/asf/ant-core/bootstrap/etc/junit-frames-xalan1.xsl Upgrade Xalan using the JDK endorsement mechanism

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.

With Ant 1.7 we had to drop support Xalan-J 1, since Xalan-J 1 has not available anymore for quite some time.

### Parameters

Attribute | Description | Required
tofile | The name of the XML file that will aggregate all individual XML testsuite previously generated by the JUnit task. | No. Default to TESTS-TestSuites.xml
todir | The directory where should be written the file resulting from the individual XML testsuite aggregation. | No. Default to current directory

### Nested Elements

#### fileset

`junitreport` collects individual xml files generated by the JUnit task using the nested `<FileSet>` element.

#### report

Generate a browsable report based on the document created by the merge.

### Parameters

Attribute | Description | Required
format | The format of the generated report. Must be "noframes" or "frames". | No, default to "frames"
styledir | The directory where the stylesheets are defined. They must be conforming to the following conventions: frames format: the stylesheet must be named junit-frames.xsl. noframes format: the stylesheet must be named junit-noframes.xsl. | No. Default to embedded stylesheets.
todir | The directory where the files resulting from the transformation should be written to. | No. Default to current directory

Ant assumes the following concerning the `frames` and `noframes` formats :

The `frames` format uses a stylesheet which is generating output only by redirecting.

The `noframes` format does not use redirecting and generates one file called `junit-noframes.html`.

Custom versions of `junit-frames.xsl` or `junit-noframes.xsl` must adhere to the above conventions.

### Nested Element of the report tag

#### param

Since Ant 1.7the report tag supports nested param tags. These tags can pass XSL parameters to the stylesheet.

### Parameters

Attribute | Description | Required
name | Name of the XSL parameter | Yes
expression | Text value to be placed into the param. Was originally intended to be an XSL expression. | Yes
if | The param will only passed if this property is set. | No
unless | The param will only passed unless this property is set. | No

### Example of report

>     <junitreport todir="./reports">
>       <fileset dir="./reports">
>         <include name="TEST-*.xml"/>
>       </fileset>
>       <report format="frames" todir="./report/html"/>
>     </junitreport>

would generate a `TESTS-TestSuites.xml` file in the directory `reports` and generate the default framed report in the directory `report/html`.

### Example of report with xsl params

>     <junitreport todir="${outputdir}">
>         <fileset dir="${jrdir}">
>             <include name="TEST-*.xml"/>
>         </fileset>
>         <report todir="${outputdir}/html"
>             styledir="junitreport"
>             format="frames">
>             <param name="key1" expression="value1"/>
>             <param name="key2" expression="value2"/>
>         </report>
>     </junitreport>

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