All Implemented Interfaces:
XMLConstants

public class XMLResultAggregator
extends Task
implements XMLConstants

Aggregates all <junit> XML formatter testsuite data under a specific directory and transforms the results via XSLT. It is not particulary clean but should be helpful while I am thinking about another technique.

The main problem is due to the fact that a JVM can be forked for a testcase thus making it impossible to aggregate all testcases since the listener is (obviously) in the forked JVM. A solution could be to write a TestListener that will receive events from the TestRunner via sockets. This is IMHO the simplest way to do it to avoid this file hacking thing.

Constant Field Values
Constructor Detail

XMLResultAggregator

public XMLResultAggregator()
Method Detail

createReport

public AggregateTransformer createReport()
Generate a report based on the document created by the merge.


setTofile

public void setTofile(java.lang.String value)
Set the name of the aggregegated results file. It must be relative from the todir attribute. If not set it will use DEFAULT_FILENAME

Parameters:
value - the name of the file.
See Also:
setTodir(File)

setTodir

public void setTodir(java.io.File value)
Set the destination directory where the results should be written. If not set if will use DEFAULT_DIR. When given a relative directory it will resolve it from the project directory.

Parameters:
value - the directory where to write the results, absolute or relative.

addFileSet

public void addFileSet(FileSet fs)
Add a new fileset containing the XML results to aggregate

Parameters:
fs - the new fileset of xml results.

execute

public void execute()
             throws BuildException
Aggregate all testsuites into a single document and write it to the specified directory and file.

Overrides:
execute in class Task
Throws:
BuildException - thrown if there is a serious error while writing the document.

getDestinationFile

protected java.io.File getDestinationFile()
Get the full destination file where to write the result. It is made of the todir and tofile attributes.

Returns:
the destination file where should be written the result file.

getFiles

protected java.io.File[] getFiles()
Get all .xml files in the fileset.

Returns:
all files in the fileset that end with a '.xml'.

writeDOMTree

protected void writeDOMTree(org.w3c.dom.Document doc,
                            java.io.File file)
                     throws java.io.IOException
Write the DOM tree to a file.

Parameters:
doc - the XML document to dump to disk.
file - the filename to write the document to. Should obviouslly be a .xml file.
Throws:
java.io.IOException - thrown if there is an error while writing the content.

createDocument

protected org.w3c.dom.Element createDocument()

Create a DOM tree. Has 'testsuites' as firstchild and aggregates all testsuite results that exists in the base directory.

Returns:
the root element of DOM tree that aggregates all testsuites.

addTestSuite

protected void addTestSuite(org.w3c.dom.Element root,
                            org.w3c.dom.Element testsuite)

Add a new testsuite node to the document. The main difference is that it split the previous fully qualified name into a package and a name.

For example: org.apache.Whatever will be split into org.apache and Whatever.

Parameters:
root - the root element to which the testsuite node should be appended.
testsuite - the element to append to the given root. It will slightly modify the original node to change the name attribute and add a package one.
