== Creating the test database
|
|
|
|
The default names for the test databases are "activerecord_unittest" and
|
|
"activerecord_unittest2". If you want to use another database name then be sure
|
|
to update the connection adapter setups you want to test with in
|
|
test/connections/<your database>/connection.rb.
|
|
When you have the database online, you can import the fixture tables with
|
|
the test/fixtures/db_definitions/*.sql files.
|
|
|
|
Make sure that you create database objects with the same user that you specified in i
|
|
connection.rb otherwise (on Postgres, at least) tests for default values will fail.
|
|
|
|
== Running with Rake
|
|
|
|
The easiest way to run the unit tests is through Rake. The default task runs
|
|
the entire test suite for all the adapters. You can also run the suite on just
|
|
one adapter by using the tasks test_mysql_ruby, test_ruby_mysql, test_sqlite,
|
|
or test_postgresql. For more information, checkout the full array of rake tasks with "rake -T"
|
|
|
|
Rake can be found at http://rake.rubyforge.org
|
|
|
|
== Running by hand
|
|
|
|
Unit tests are located in test directory. If you only want to run a single test suite,
|
|
or don't want to bother with Rake, you can do so with something like:
|
|
|
|
cd test; ruby -I "connections/native_mysql" base_test.rb
|
|
|
|
That'll run the base suite using the MySQL-Ruby adapter. Change the adapter
|
|
and test suite name as needed.
|
|
|
|
You can also run all the suites on a specific adapter with:
|
|
|
|
cd test; all.sh "connections/native_mysql"
|
|
|
|
== Faster tests
|
|
|
|
If you are using a database that supports transactions, you can set the
|
|
"AR_TX_FIXTURES" environment variable to "yes" to use transactional fixtures.
|
|
This gives a very large speed boost. With rake:
|
|
|
|
rake AR_TX_FIXTURES=yes
|
|
|
|
Or, by hand:
|
|
|
|
AR_TX_FIXTURES=yes ruby -I connections/native_sqlite3 base_test.rb
|
|
|
|
== Testing with Oracle
|
|
|
|
In order to allow for testing against Oracle using an "arunit" schema within an existing
|
|
Oracle database, the database name and tns connection string must be set in environment
|
|
variables prior to running the unit tests.
|
|
|
|
$ export ARUNIT_DB_NAME=MYDB
|
|
$ export ARUNIT_DB=MYDB
|
|
|
|
The ARUNIT_DB_NAME variable should be set to the name by which the database knows
|
|
itself, ie., what will be returned by the query:
|
|
|
|
select sys_context('userenv','db_name') db from dual
|
|
|
|
And the ARUNIT_DB variable should be set to the tns connection string.
