# Turn off transactional fixtures if you're working with MyISAM tables in MySQL
# Transactional fixtures accelerate your tests by wrapping each test method
# in a transaction that's rolled back on completion. This ensures that the
# test database remains unchanged so your fixtures don't have to be reloaded
# between every test method. Fewer database queries means faster tests.

# Every Active Record database supports transactions except MyISAM tables
# in MySQL. Turn off transactional fixtures in this case; however, if you
# don't care one way or the other, switching from MyISAM to InnoDB tables
# is recommended.

# Instantiated fixtures are slow, but give you @david where otherwise you
# would need people(:david). If you don't want to migrate your existing
# test cases which use the @david style and don't mind the speed hit (each
# instantiated fixtures translates to a database query per test method),
# then set this back to true.
self.use_instantiated_fixtures = false
# Add more helper methods to be used by all tests here...
