# Running tests: You can test the creation of the input files and the event generation step: ``` bash source /cvmfs/sw-nightlies.hsf.org/key4hep/setup.sh cd build ctest --verbose ``` ⚠️ **Warning**: Always run this scheme as cmake and make set up the environment variables correctly for the execution of the generation step ## Running with local modifications of the code: Setting up with ```bash source /cvmfs/sw-nightlies.hsf.org/key4hep/setup.sh cd build cmake ../CMakeLists.txt -DCMAKE_INSTALL_PREFIX=../install make install k4_local_repo ``` will extract the global paths and set the executables to the local install directory instead of the release. The runscripts therefore will run automatically with the executables you have modified
