One option might be a "two phased commit". This would need multiple SVN repositories, probably controlled by SVK.

The commit request goes on to the "staging repository", where it is checked out to the testing sandbox, built, completes the test suite and is pushed to the "live repository" if all is OK. If the tests fail, the "staging commit" is undone.
