Update tests to use standard conf dir

[edewata]

Normally the Tomcat conf dir is located immediately under the instance dir. For PKI server, which is based on Tomcat, the location is /var/lib/pki/<instance>/conf.

Depending on the deployment scenario the config files might be mounted from a different location (e.g. /etc/pki/<instance> on Fedora) and the standard conf dir will be just a link to the actual location.

To ensure that the tests are valid for all deployment scenarios they have been updated to use the standard conf dir instead of the Fedora-specific one.

LGTM

I have just a curiosity. In my mind /etc is the configuration folder so for me it was the place to use for the configuration. What is the scenario to solve where configuration files are in different folder?

@fmarco76 Thanks! I'll merge but feel free to continue the discussion.

From a generic Tomcat perspective the conf folder is located under the instance folder. We use /etc because Fedora uses FHS so the conf is just a link to /etc. Other OSes or containers might use different locations (e.g. /data) but in any case the conf will always be under the instance folder and point to the actual location. See the following tickets:

• https://bugzilla.redhat.com/show_bug.cgi?id=2265995
• https://issues.redhat.com/browse/RHEL-20465

So to make sure the code, the tests, and the docs will be valid for all cases we need to use the standard conf location and let the link translate it into the actual location. This PR is just for the tests, but I'll be updating the code & the docs as well later.
