[test] New Handling of database for test.
This patch adds a new TestDataBaseHandler class.
TestDataBaseHandler are in charge of Setup, backup, restore, connection,
repository caching and cleanup for database used during the test.
TestDataBaseHandler reuse code and logic previously found in cubicweb.devtools
functions and devtools.testlib.CubicwebTC. TestDataBaseHandler is an abstract
class and must be subclassed to implement functionalities specific to each
driver.
TestDataBaseHandler can store and restore various database setups.
devtools.testlib.CubicwebTC gains a test_db_id class attribute to specify that
its TestCase uses a specific database that should be cached. The
pre_setup_database class method is used to setup the database that will be
cached. The setup_database method is kept uncached.
The same TestDataBaseHandler are reused for every test using the same config
object. TestDataBaseHandler try to reuse Repository objects as much as
possible.
All cubicweb test have been updated.
.. _pre_defined_entity_types:
Pre-defined entities in the library
-----------------------------------
The library defines a set of entity schemas that are required by the system
or commonly used in *CubicWeb* instances.
Entity types used to store the schema
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* _`CWEType`, entity type
* _`CWRType`, relation type
* _`CWRelation`, relation definition
* _`CWAttribute`, attribute relation definition
* _`CWConstraint`, `CWConstraintType`, `RQLExpression`
Entity types used to manage users and permissions
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* _`CWUser`, system users
* _`CWGroup`, users groups
* _`CWPermission`, used to configure the security of the instance
Entity types used to manage workflows
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* _`Workflow`, workflow entity, linked to some entity types which may use this workflow
* _`State`, workflow state
* _`Transition`, workflow transition
* _`TrInfo`, record of a transition trafic for an entity
Other entity types
~~~~~~~~~~~~~~~~~~
* _`CWCache`, cache entities used to improve performances
* _`CWProperty`, used to configure the instance
* _`EmailAddress`, email address, used by the system to send notifications
to the users and also used by others optionnals schemas
* _`Bookmark`, an entity type used to allow a user to customize his links within
the instance
* _`ExternalUri`, used for semantic web site to indicate that an entity is the
