my memory failed, the folder is only named "storage/" (even if the Bugzilla component is Toolkit / Storage), sorry about that. You can run "./mach test storage/" Last question, ensure you .mozconfig is not configured to do an artifact build, because those don't compile C++ code. If it contains --enable-artifact-builds it's not ok.
