12. Other database stuff
• Abstract base domain classes
– These now result in a table
• findOrCreateWhere()
• findOrSaveWhere()
def user = User.findByLogin('admin')
if (!user) {
def user = User.findOrSaveWhere(login: 'admin')
user = new User(login: 'admin')
user.save(failOnError: true)
}

14. Unit testing pre-1.4
• mockDomainClass() had only partial GORM support
– always lagged changes in GORM
• Inheritance-based
– hierarchy duplicated for Spock
– difficult to extend
• Weak support for web-related testing
– controllers
– tag libraries

15. The mixin approach
class MyControllerUnitTests extends ControllerUnitTestCase {
void setUp() {
mockDomain(Person, [
new Person(...),
new Person(...) ])
}
void testIndex() {
def model = this.controller.index()
...
}
}
