All Together Now

Groovy on RailsGroovy on Grails

Grails


Grails Recipe

● Take most popular Java web techs


● Apply dollop of groovy glue● Conventions from top to bottom● Minimal boiler plate code


Your Choice of 745 Fixings

●


Bake with fully integrated testing tools


Enjoy!

● Full stack web-application framework


Running App in 3 Lines

● grails create-app bookstore● cd bookstore● grails run-app


Add MVC

● create-domain-class Author● cre<tab> Book● create-scaffold-controller <tab> Author● <up arrow> Book


Define Domain


New in 2.0

● Much improved interactive shell● Better class reloading● Web-based dbconsole


dbconsole

● drool,drool, drool


Get Real

● Authentication● Test Data● Testing● Audit Logging● Monitoring


IDE Integration

● Intellij Rocks– Does require $ for Ultimate Edition

● STS – Spring Source Toolsuite– A solid “meh”


Plugins

● Project Overlay● Augment Build● Add Common Libs● Add Capabilities


Authentication

● Do it first● Avoid mocking stuff for user session


Spring Security Plugin

● grails install-plugin spring-security-core

or● BuildConfig.groovy:● compile ':spring-security-core:1.2.7.2'● grails s2-quickstart bookstore.auth

BookstoreUser AuthRole●


BuildConfig.groovy

● Ivy Dependency Management● SCM● Repository Deployment● Plugin Definitions


Init Security

● grails s2-quickstart bookstore.auth BookstoreUser AuthRole


Config.groovy

● Tip: Break it up● Makes it easier to upgrade grails● Easier to find settings of different types● Don't forget to test it


Unit vs Integration Tests

● Grails 2 unit test enhancements● Integration tests go through init sequence

● create-integration-test BootStrap● test-app integration:● open test-report


Back to Security


Lock it Down

● Can use Annotation in controllers

or● Centralized url-access map

http://grails-plugins.github.com/grails-spring-security-core/docs/manual/


Fixtures Plugin

● grails install-plugin fixtures● Concise DSL for creating domain objects● Test data sets● Initialization data


Fixtures Shortcomings

● Can't load external file● Doesn't load in production● No easy “if exists” check● Can work around all of these


Fixtures Plugin

● Fixture for roles and system user● Fixture for test/demo users● Test! Test! Test!


Why so many tests?

● It's easy● Compile time checking no longer there● Do you value your sanity?


Productivity Chart


Grails without Tests


Activate Fixtures

● A bit about Bootstrap.groovy


App-Specific Config Settings

● ConfigSlurper - a very smart properties file● Remember - can overload with other files


BuildTestData Plugin

● Fills in non-essential bean fields● Keeps data in-tests

– Also Integrates with Fixture plugin

● As of last week, works in Unit Tests– new Book().validate() vs

Book.build().validate()


● Have– DB persistence, authentication, unit and

integration tests, auto-initialized user and data sets

● Need– Audit logging, Load monitoring, remote

debugging, functional tests, code coverage metrics, Lucene indexed queries, UI niceties

Status Check


● grails install-plugin audit-logging

● grails install-plugin code-coverage

● grails install-plugin console

● grails install-plugin codenarc

● grails install-plugin geb

● grails install-plugin grails-melody

● grails install-plugin runtime-logging

…Oh eff it...● Add plugin dependencies to BuildConfig

Bam!


● CodeNarc– Warning: Will not run in interactive console

● Coberturra– Need to tweak include/exclude sets

● Both integrate well with Jenkins

Code Analysisand

Test Coverage


● static auditable = true● Hooks into grails persistence events● Record changes down to property level● Integrates with spring security to capture

user● Controller to view some audit info

Audit Logging


● SELECT * FROM AUDIT_LOG order by id desc

Audit Logging


Monitoring with Melody


● dbconsole● console● App-info

– Warning: Not working with grails 2 yet

Remote Debugging


● Have– DB persistence, authentication, unit and

integration tests, auto-initialized user and data sets, audit logging, load monitoring, remote debugging, code coverage metrics

● Need– functional tests, Lucene indexed queries,

UI niceties

Status Check


● static searchable = true● Lucene index against domain classes

Searchable Plugin


● Functional Testing with Geb

Or● Tags and Tag Cloud

Audience Choice


● static searchable = true● Lucene index against domain classes

Taggable and Tag Cloud
