   1 == Creating the test database
   2
   3 The default names for the test databases are "activerecord_unittest" and
   4 "activerecord_unittest2". If you want to use another database name then be sure
   5 to update the connection adapter setups you want to test with in
   6 test/connections/<your database>/connection.rb.
   7 When you have the database online, you can import the fixture tables with
   8 the test/schema/*.sql files.
   9
  10 Make sure that you create database objects with the same user that you specified in
  11 connection.rb otherwise (on Postgres, at least) tests for default values will fail.

  13 == Running with Rake
  14
  15 The easiest way to run the unit tests is through Rake. The default task runs
  16 the entire test suite for all the adapters. You can also run the suite on just
  17 one adapter by using the tasks test_mysql, test_sqlite, test_postgresql or any
  18 of the other test_ tasks. For more information, checkout the full array of rake
  19 tasks with "rake -T"

  21 Rake can be found at http://rake.rubyforge.org

  23 == Running by hand
  24
  25 Unit tests are located in test/cases directory. If you only want to run a single test suite,
  26 you can do so with:
  27
  28    rake test_mysql TEST=test/cases/base_test.rb
  29
  30 That'll run the base suite using the MySQL-Ruby adapter.  Some tests rely on the schema
  31 being initialized - you can initialize the schema with:
  32
  33   rake test_mysql TEST=test/cases/aaa_create_tables_test.rb
