###PHPUnit logfile XLST template

This fileset provides an easy way to view the PHPUnit XML (JUnit) logfiles in a human readable manner using a web browser.

Use this either in combination with the accompanying html file or add the following tag straight after the xml opening tag of the logfile: <?xml-stylesheet type="text/xsl" href="phpunit.xslt"?>

The thresholds used for the colour-coding and whether or not to show detail for successfull tests can be changed by adjusting the variables at the top of the xslt file.
