Good day,

It seems to me that some tests may require resources that can't be put
to SVN, for example, non-readable files. Non-writable files may fall
in this category, too - I think (sorry it I'm wrong) that after
commit/checkout from SVN they become writable by the owner. Another
example of such resources may be huge files. It's impossible to put
such resources to SVN but they may be created in the build process or
on fly before executing tests.  Maybe it's worth to specify a common
approach for such resources, maybe a build target or something like
that.

It is not a good idea to put creation of such resources in something
like setUp() method in JUnit test because who knows if a read-only
file created by VM under test is really read-only or not :)
