When running the test suite using MySQL, a lot of time is spent creating the database, running the migrations, and then dropping the database when the test finishes. Obviously we need a clean database at the start of each test, but that doesn't mean we need to run the migrations every single time. Setting parallel_class to True in .stestr.conf makes all the tests in a given class run in the same subprocess, whilst retaining parallelisation when there is more than one test class discovered. This commit moves the setup and cleanup of the database to the class level rather than the test level, so that the slow migration step only runs once per test class, rather than once per test. Cleaning the database between tests is done by deleting everything from the tables (excepting the tables that are populated by the migrations themselves), and resetting any autoincrement counters. This reduces the runtime of the individual tests by an order of magnitude locally, from about 10 seconds per test to about 1 second per test with this patch applied. There is still some overhead for each class, but I can now run the test suite in about 15 minutes with MySQL on my machine, as opposed to over an hour previously.

Storyboard
Storyboard is a task tracker created to serve the needs of highly-distributed systems that span multiple projects, to enable cross-project work on a massive scale. Concepts were adapted from existing tools, and as many potential points of contention were removed as possible, to better facilitate coordination of project work by stakeholders with widely varied interests and needs.
