You would need to have an oracle-profile, mysql-profile,
postgres-profile and mongo-db profile. I think it might be easier to
keep track of the machines in code as is done in
DBAppenderIntegrationTest. Using profiles has the advantage of
decoupling the tests run from the test code. The isConformantHost
check is quick-and-dirty but gets the job done.

There is no Jenkins instance for logback/logback-extensions. There was
a CI for logback a few years back but I no longer had the time to
maintain the instance.

That would be great thanks.

Looking at [1], although ootb there is a javaagent attached to the
JVM. I might be wrong here but using a Java agent to run tests seems
like an awfully heavy handed method. It affects every single class
loaded into memory. The MockitoJUnitRunner approach seems less
invasive imho.

Thank you. To be precise, it's actually logback-mongodb-parent pom
module plus 3 children: logback-mongodb-core, logback-mongodb-classic
and logback-mongodb-access.

I think it would be easier if you could push the docs onto 
http://logback.qos.ch directly. We can discuss this later.
