+\subsection inside_tests_debian Debian builders
+
+Since SimGrid is packaged in Debian, we benefit from their huge
+testing infrastructure. That's an interesting torture test for our
+code base. The downside is that it's only for the released versions of
+SimGrid. That is why the Debian build does not stop when the tests
+fail: post-releases fixes do not fit well in our workflow and we fix
+only the most important breakages.
+
+The build results are here:

+SonarQube is an open-source code quality analysis solution. Their nice
+code scanners are provided as plugin. The one for C++ is not free, but
+open-source project can use it at no cost. That is what we are doing.
