  1 +== Creating the test database
  2 +
  3 +The default name for the test databases is "activerecord_versioned". If you
  4 +want to use another database name then be sure to update the connection
  5 +adapter setups you want to test with in test/connections/<your database>/connection.rb.
  6 +When you have the database online, you can import the fixture tables with
  7 +the test/fixtures/db_definitions/*.sql files.
  8 +
  9 +Make sure that you create database objects with the same user that you specified in i
  10 +connection.rb otherwise (on Postgres, at least) tests for default values will fail.
  11 +
  12 +== Running with Rake
  13 +
  14 +The easiest way to run the unit tests is through Rake. The default task runs
  15 +the entire test suite for all the adapters. You can also run the suite on just
  16 +one adapter by using the tasks test_mysql_ruby, test_ruby_mysql, test_sqlite,
  17 +or test_postresql. For more information, checkout the full array of rake tasks with "rake -T"
  18 +
  19 +Rake can be found at http://rake.rubyforge.org
  20 +
  21 +== Running by hand
  22 +
  23 +Unit tests are located in test directory. If you only want to run a single test suite,
  24 +or don't want to bother with Rake, you can do so with something like:
  25 +
  26 + cd test; ruby -I "connections/native_mysql" base_test.rb
  27 +
  28 +That'll run the base suite using the MySQL-Ruby adapter. Change the adapter
  29 +and test suite name as needed.
  30 +
  31 +== Faster tests
  32 +
  33 +If you are using a database that supports transactions, you can set the
  34 +"AR_TX_FIXTURES" environment variable to "yes" to use transactional fixtures.
  35 +This gives a very large speed boost. With rake:
  36 +
  37 + rake AR_TX_FIXTURES=yes
  38 +
  39 +Or, by hand:
  40 +
  41 + AR_TX_FIXTURES=yes ruby -I connections/native_sqlite3 base_test.rb
