[gentoo-user] Strategies for testing an ebuild

[Anton]

Hi there,

I am taking on maintaining a package in gentoo-sci overlay. What are 
good ways to test that my ebuild works before creating a pull request?

I am thinking to install a Gentoo Prefix, snapshot its "vanilla" state, 
and run `emerge $mypackage` in the vanilla Prefix as a test. Are there 
better strategies?

Thanks,
Anton
