c.t.l.LaunchpadLayer(DatabaseLayer, LibrarianLayer, MemcachedLayer) : class documentation

Known subclasses: canonical.testing.layers.LaunchpadFunctionalLayer, canonical.testing.layers.LaunchpadScriptLayer

Provides access to the Launchpad database and daemons.

We need to ensure that the database setup runs before the daemon setup, or the database setup will fail because the daemons are already connected to the database.

This layer is mainly used by tests that call initZopeless() themselves. Most tests will use a sublayer such as LaunchpadFunctionalLayer that provides access to the Component Architecture.
