I want to check Selenium's coverage of my web app, which runs on mod_perl2 on CentOS 6.5.
So I installed Devel::Cover, put use Devel::Cover; in my httpd.conf's <Perl> section, and restarted Apache. It immediately writes some coverage data from my custom ErrorLogging.pm module, but then if I hit any of the app's pages via a browser, nothing further happens.
I also tried changing this in httpd.conf:
StartServers 1
MinSpareServers 1
MaxSpareServers 1
...just to make sure it'd be collecting all data from the same process. However, after restarting Apache and trying again, the result was the same.
UPDATE: I also tried launching httpd with -D ONE_PROCESS as mentioned in this thread, but the result was more or less the same, except that I had to Ctrl+C the service when done testing, because it takes over the terminal, and at that point it segfaulted. But the coverage database in the end was virtually identical.
The docs don't mention anything different that I can see. How can I get Devel::Cover to record coverage data for code execution that happens in response to actual browser requests via mod_perl2?
