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 |

91 | + # then that field is reflected in the versioned model as 'versioned_type' by default. | ||
