I think it depends on what about the tests are related to.
If their main aim is to verify regressions at development time you can
certainly be a little bit more aggressive and shoot for 2.5 (or even
If the aim is to have automated test running as part of the build
process to validate the bits then trying to be conservative will help
quite a lot given build systems often rely on what is supported in the
current OS you are building on and adding different software is cause of
concern as it may invalidate other assumptions of the build system.
