I take it you use "Depends: @" or no Depends: line at all? This is just a
shortcut for simple packages, but not at all useful for large multi-binary
sources. For them it's much better to explicitly specify which packages a test
needs, and you can test alternative packages in different tests.

Please be more specific. If a package is uninstallable because its dependencies
conflict, then that its an RC bug in that package (and britney should already
spot that). If your test dependencies specify conflicting packages, then that
test just needs to be fixed. autopkgtest does not prescribe anything there,
aside from the optional "@" shortcut.
