Testability: how to find the right frogtests?

[proycon]

Since the frog tests are in a separate repository, automatic testing of any arbitrary version (that includes old versions) is not possible without explicitly establishing which frogtests version is needed for which frog version. This is relevant for the debian package build process. How can we solve this?

The same issue applies to libfolia and ucto.

This is quite hard. Tests may depend on the frog version, but also on frogdata, ucto or libfolia versions.
The only reasonable thing to do is probably add more test cases to 'make check'
