      tests: Teach test driver to pass tests when run with wendelin.core 2 · cdbeda8d
      Kirill Smelkov authored
      This patch is similar to
      nexedi/erp5@530e8b4e
      (nexedi/erp5!1445) and amends Wendelin test
      driver to run tests on a real storage and spawn WCFS as needed.
      
      Running tests on a real storage instead of in-RAM MappingStorage is
      required in wendelin.core 2 case, because WCFS and Zope need to access the
      same ZODB, and if Zope keeps data inside in-RAM MappingStorage, there
      is no easy way for WCFS to access it. In such a case tests are failing as e.g.

      -> Fix it by using a real storage for tests via --load/--save hack, and via
      --with_wendelin_core requesting to spawn WCFS when built with wendelin.core 2.
