Yes, the registration unit in FPCUnit is very simple, I've actually
included it as an example on how to add the test suites more than a set
of utility classes. In fact you get the root test suite through
GetTestRegistry function and then you add any hierarchy you wish just by
creating other suites and building the tree. So your unit is very handy
for this and spares some typing.

Yes, if it wasn't for your huge test suite, FPCUnit would not have been
improved. The first time I've heard from you, some two years ago I
didn't even believe it could handle such a suite gracefully.
There is still many improvements that can be made, but my spare time is
quite scarce lately. I'm waiting for my vacations :)

I agree, the differences are not many, and not important, except for the
assert methods that are class methods in JUnit and FPCUnit.

You need them if you want to understand the internals. JUnit is a live
demonstration that flexibility in OOP design leads to code that is very
difficult to understand, due to the many indirections.
But I guess in this case it's justified by the fact that the framework
had to be also easy to use and had to spare on typing by the end user.
Only when I wrote myself the framework in pascal, following the java
code, I was able to understand it completely (and still I'm convinced
that after so much refactoring on the junit side, some indirections were
