Once everything is built, you may want to test the result. SimGrid
comes with an extensive set of regression tests (as described in the
-@ref inside_tests "insider manual"). The tests are run with ``ctest``,
-that comes with CMake. We run them every commit and the results are
-on `our Jenkins <https://ci.inria.fr/simgrid/>`_.
