sqlalchemy.testing.plugin.bootstrap

Bootstrapper for test framework plugins.

The entire rationale for this system is to get the modules in plugin/ imported without importing all of the supporting library, so that we can set up things for testing before coverage starts.

The rationale for all of plugin/ being in the supporting library in the first place is so that the testing and plugin suite is available to other libraries, mainly external SQLAlchemy and Alembic dialects, to make use of the same test environment and standard suites available to SQLAlchemy/Alembic themselves without the need to ship/install a separate package outside of SQLAlchemy.
