I am running Zend Framework 1.10 on Ubuntu 10.04, just installed Xdebug to generate code coverage, via PECL.

If I run phpunit like so:

$ phpunit --coverage-html ~/coverage

It works just fine. Unittests run, then code coverage output is generated. No error messages or warnings.

But if I do:

$ phpunit

The tests run fine, but when code coverage begins, I get this:

Generating code coverage report, this may take a moment.PHP Warning:  mkdir(): Permission denied in /usr/share/php/PHPUnit/Util/Filesystem.php on line 209
PHP Stack trace:

Before I installed Xdebug, running phpunit without any arguments worked just fine.

I presume this is just a silly permissioning problem stemming from my PECL installation of Xdebug, but it looks like everything in /usr/share/php/phpunit is supposed to be permissioned as root, soooooo...any ideas?

What are the permissions on the directory where you are running phpunit? – David Harkness Oct 11 '11 at 8:54
Read only... it used to work though... – stantonk Oct 22 '11 at 6:21

The error message just tells you that mkdir can't create a folder somewhere but not where it is trying to do so.

I would assume you have an phpunit.xml.dist in which a <logger> of the type coverage-html is defined with a target that doesn't exist on your machine which your current user doesn't have write access too.

PHPUnit doesn't try to generate a coverage report without somneone telling it do and if you don't do it on the cli a phpunit.xml is the only option left.
