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) } 12Monday, 30 May 2011 12

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 14Monday, 30 May 2011 14

The mixin approach class MyControllerUnitTests extends ControllerUnitTestCase { void setUp() { mockDomain(Person, [ new Person(...), new Person(...) ]) } void testIndex() { def model = this.controller.index() ... } } 15Monday, 30 May 2011 15

The mixin approach class MyControllerUnitTests { void setUp() { mockDomain(Person, [ new Person(...), new Person(...) ]) } void testIndex() { def model = this.controller.index() ... } } 16Monday, 30 May 2011 16

The mixin approach @TestFor(MyController) @Mock(Person) class MyControllerUnitTests { void setUp() { mockDomain(Person, [ new Person(...), new Person(...) ]) } void testIndex() { def model = this.controller.index() ... } } 17Monday, 30 May 2011 17

The mixin approach @TestFor(MyController) @Mock(Person) class MyControllerUnitTests { void setUp() { new Person(...).save() new Person(...).save() } void testIndex() { def model = this.controller.index() ... } } 18Monday, 30 May 2011 18

The mixin approach (optional) @TestFor(MyController) @Mock(Person) class MyControllerUnitTests { @Before void before() { new Person(...).save() new Person(...).save() } @Test void indexAction() { def model = this.controller.index() ... } } 19Monday, 30 May 2011 19

Support for testing... • Tag libraries • Command objects • XML & JSON responses • File upload • View and template rendering • Filters • URL mappings • Criteria queries • and more! 20Monday, 30 May 2011 20

New automatic reloading • Reloading in run-app works with – Typed service references – Domain classes – src/groovy, src/java • Any command with -agent • Interactive mode and integration tests? 22Monday, 30 May 2011 22

Plugin portal + Plugin usage tracking + Grails usage tracking + More info about plugins How many We don’t know plugin? people use each Licence Developers Issue tracker SCM Dependencies (JAR & plugin) 23Monday, 30 May 2011 23

Other stuff • Snapshot handling fixed – No need to clear Ivy cache when new snapshot available • Interactive mode – Eliminate Permgen errors? • H2 console – Out of the box interrogation of database • Binary plugins – Plugins as JAR dependencies! • AST transforms – Use domain classes from Java! – Real ‘errors’ and ‘log’ properties! • Public methods on controllers == actions 24Monday, 30 May 2011 24
