"""

Bootstrapper for nose/pytest 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.
|
|
|
|
NOTE: copied/adapted from SQLAlchemy master for backwards compatibility;
|
|
this should be removable when Alembic targets SQLAlchemy 1.0.0.
