I am not finished with the analysis (MacGyver) tool, but I thought I would put up what I have so far on the MediaWiki site. I have created a web page in my user space for the Parser Test code coverage analysis -
http://www.mediawiki.org/wiki/User:Dnessett/Parser_Tests/Code_Coverage
I would appreciate it if someone familiar with the parser would at least glance at the per file statistics for a sanity check. Some things that worry me are:
* parserTests seems to visit Special:Nuke. Does this make sense?
* Only about 72% of Parser.php is exercised. Is this reasonable?
* Xdebug is reporting that the Parser only has 2975 lines of executable code. This contrasts to the report by Happy-Mellon that there is 11,000 lines of code in Parser.php. Are there really that many non-executable lines of code in the parser or is Xdebug missing a whole bunch?
