A JUnit XSL Transform For PHPUnit Logging

I recently worked on a PHP application with a PHPUnit test suite. Not finding a good way to view the test run results, I settled on logging the output into JUnit format and then applied the style sheet to the XML file so that I can through the XML file into a browser.
PHPUnit Execution and XML Update
1
time phpunit --testsuite "Application Test Suite" --log-junit public/testresults.xml & sed -i 's/<!--xml version="1.0" encoding="UTF-8"?-->/<!--xml version="1.0" encoding="UTF-8"?-->\n<!--xml-stylesheet type="text\/xsl" href="junit.xslt"?-->/g' public/testresults.xml
Not sure why, but finding a decent transform for the JUnit output was more diffcult than expected. I decided to extended an XSL transform in this StackOverflow answer. It is a pretty good start, plain text, but I can work with it.

After applying Bootstrap styling, the end result is a pleasantly styled JUnit view in a browser. For some reason, FireFox was not applying the bootstrap CSS file, so I just brought in the styles that I needed, thus the style block.
