Zoe Slattery has posted an update about the TestFest events happening around the world and the contributions they've been making to the overall cause of getting PHP code coverage as complete as possible.
Groups from all over the world have contributed 554 new tests for PHP since April 1st 2009. Of these, 327 have already been moved into PHP's CVS (thanks Felipe!). The results of running tests on a Linux 32 bit platform can be seen here (sorry about the colour scheme), the user groups who have contributed are also listed. We also run the tests on a 64 bit Linux platform here, but this only runs PHP5.3 and PHP5.2.
She's also run some complete code coverage tests (after fighting a bit with ccache and lcov) and came up with a two percent increase overall (including a huge jump in the ext/ldap extension's coverage from about nine percent up to almost ninety percent!)
