Tests are always in separate package (so that you don't have to load them in productive code). As you can see in the list, most packages have an associated test package: Seaside-Session and Seaside-Tests-Session You find a more complicated example of a group of packages that also includes platform specific code at the bottom of <http://code.google.com/p/seaside/wiki/PackageNaming>.
