There are two major part of test suite, one is a coded with C, which
check that functional interface to the core libraries is OK. That is
what I would call as unit tests.

The second part (major by code and by execution time) is written by
python, and will drive cmdline svn, svnlook and svnadmin, and verify
that they work OK.

There are three different targets for testing:
make check # test done by using ra_local access
make davcheck # test done by using ra_dav access
make svncheck # test done by using ra_svn access

And top of that you could select which backend to test, BDB or FSFS.

I would say that this is exactly "verifying that the user system is
cabaple to support SVN"

There is one script for that, which tries to do that out-of-box:
<http://svn.collab.net/repos/svn/trunk/subversion/tests/clients/cmdline/davautocheck.sh>

Why not, you have just compiled quite complicated piece of software
and libraries, don't you like to know that it works as adverticed,
do you?

One way to speed up the testing is to run tests over ramdisk:
