Instance Method Details

#test_data(&blk) ⇒ Object

Hook for creating test data ONCE alongside fixtures that will then be rolled back via transactions after each test, so you can set up complex data via Factories etc. without the speed drop.

Please note that you’ll have to set up empty fixture files (and load them, see the list of fixtures above) in order to clean up the database before you launch your tests.

Usage: In your test class, do:

test_data do
  Factory.create(:foobar)
  # etc...
end

The foobar record will be available in all your tests and rolls back even if you modify it in your test cases thanks to transactions.
