It depends on the build technology (e.g. Ant, Maven, MSBuild or FianlBuilder) that you use to create the source code. To test your build results in svn, you must add a few new steps at the end of build scripts. This step will simply add your build results to svn. For example, your step may contain:
svn commit -file build-output.1 build-output.2
, svn.
