1 Groovy for Java developers and testers How Java developers and testers could use Groovy to increase their efficiency AUGUST 6, 2015

2 Life Science Department, Saint-Petersburg, Russia Mikhail Denisov Demo project:

3 WHY GROOVY? Smooth Java integration. Runs on the JVM, 100% compatible with Java bytecode 1 Concise, familiar and easy to learn syntax (“syntactic sugar”) 3 Dynamic language, with static-typing and static compilation capabilities 4 GDK - the extension to the JDK 5 Metaprogramming (Builders, DSL), functional programming, scripting 6 Supported by many systems and frameworks 2

4 AstraZeneca SOA Factory project Over 20 web-services (DB and AD interaction) Service Bus proxy for each service 4 environments: dev, test, preprod, prod 3 regions: Emea, America, Asia 20 * 2 * 3 * 4 = 480 endpoints SOA Factory project

5 GROOVY BY EXAMPLES Working with database and files 1 HTML, JSON and XML parsing 2 JSON and XML generation 3 Working with SOAP-service 4 Groovlets 5 Advanced Groovy 6

6 Maven POM.xml configuration with Groovy-Eclipse-Compiler

7 GROOVY BASICS: variables and collections

8 GROOVY BASICS: closures and GDK

9 GROOVY BASICS: objects and classes

10 Working with database and files Case: update database with data from file

11 GROOVY TESTS: interface implementation with Map

12 HTML parsing with RegExp

13 JSON parsing with JsonSlurper, GPath expressions

14 JSON parsing with JsonSlurper, GPath expressions

15 XML parsing: Google News RSS

16 GROOVY METAPROGRAMMING: working with metaClass

17 GROOVY METAPROGRAMMING: expanding Java classes

18 GROOVY METAPROGRAMMING: missing method interception

19 XML GENERATION: class MarkupBuilder

20 XML GENERATION: class MarkupBuilder

21 JSON GENERATION: class JsonBuilder

22 SOAP Web Service interaction with WSLite SOAP WebService “Magic Square” WSDL: Add WSLite to pom.xml

23 SOAP Web Service interaction with WSLite

24 SOAP Web Service: service MagicSquare.groovy

25 SOAP Web Service: test MagicSquareTest.groovy

26 Groovlet: display results as HTML page web.xml – add groovy.servlet.GroovyServlet

27 Groovlet: display results as HTML page Create script src/main/webapp/scripts/magic1.groovy Build application, run it in the servlet container Browse the link Result would be like this

28 Groovlet: scripts/magic2.groovy - params,, application, context javax.servlet.ServletContext sessionjavax.servlet.HttpSession requestjavax.servlet.HttpServlet responsejavax.servlet.HttpResponse outresponse.getWriter() Groovlet implicit objects:

29 Groovlet: add parameters and HTML markup: results

30 Groovlet: script/magic3.groovy - add CSS

31 Groovlet: scripts/magic3.groovy - result

34 How many lines are needed to run it as a DSL script? please show the square_root of 1024

36 Case: we have to collect data from many independent sources (collect all jokes about Chuck)
