Topics • Why Groovy for Testing? • Groovy Intro • Web Drivers • Test Runners • Non-web Drivers • Other Tools © ASERT 2006-2009 • Going beyond Focus is on using the Groovy dynamic language for primarily functional and acceptance testing with a forward looking perspective. Also considers polyglot options. The techniques and lessons learned can be applied to other kinds of testing and are also applicable to similar languages. AJUG_SEP2009 - 2

Why Test With Groovy? ? © ASERT 2006-2009 AJUG_SEP2009 - 5

Why Test With Groovy? • Wrong first question! • Perfect second question?  X © ASERT 2006-2009 Consider first the task at hand and the organization and people fit! AJUG_SEP2009 - 6

“People Fit” / “Organization Fit” • People – Developers (familiarity with languages) – Testers (tools language familiarity) – Responsibility to create/run/maintain – BAs/SMEs (ability to read technical tests) – Consider both development and maintenance © ASERT 2006-2009 – Expected feedback from tests (JUnit/Reports) • Organization – Maturity level – Degree of automation – Tools in use – Need for adaptability AJUG_SEP2009 - 7

Why Test With Groovy? • Advantages – Easy to learn – Particularly good fit if the application you are testing is built for the JVM or your developers work with Java / JVM languages – Supports polyglot programming when needed © ASERT 2006-2009 – Easy to plug and play different testing tools – Good community & tools for professional agile • Disadvantages – Requires JVM – Less advantages if your developers using Python, .Net, PHP – Maybe your testers already know Ruby AJUG_SEP2009 - 8

Scripting/Dynamic Languages • Advantages – Lend themselves to succinct code/DSLs – Powerful – Increased Refactoring – Increased Reuse – Less prone to Brittleness © ASERT 2006-2009 – Flexibility for tool integration – Open APIs provide extensibility • Disadvantages – Can be too low level (but many options now) – Sometimes less tool support (but changing now) AJUG_SEP2009 - 9

Test Characteristics • Coverage/Traceability – Requirement coverage/traceability – Code coverage: line, branch, path, state – Transactional Tracing • Purpose – Unit, Integration, System, Customer • Manageability – Removing duplication © ASERT 2006-2009 – Managing lifecycle: shared setUp/tearDown (@Before @After) • Handling test data – Data-driven, databases, Spreadsheets, tables, keywords, random, model-driven • Large Test Volumes – Speed of feedback, performance testing • Tool evolution/longevity/cost/support/documentation – Open Source/Commercial, Critical mass/popularity • Combinability AJUG_SEP2009 - 10

Key Testing Practices • Use testing DSL’s • Look to move up the testing stack – It used to be all about the driver – Now the driver is hidden in the framework or tool stack • Apply good testing practices – Pareto analysis, bug clusters, mutation testing, test early © ASERT 2006-2009 – All pairs/equivalence partitions/orthogonal array testing – Risk-based test selection, coding for testability, use CI – Boundary value analysis, defensive programming • Plug and play testing tools – Run different drivers with different runners and different tools • Complement automated tests with exploration • Expand testing scope – Test environment readiness, test deployments AJUG_SEP2009 - 11

What is Groovy? • “Groovy is like a super version of Java. It can leverage Java's enterprise capabilities but also has cool productivity features like closures, DSL support, builders and dynamic typing.” © ASERT 2006-2009 Groovy = Java – boiler plate code + optional dynamic typing + closures + domain specific languages + builders + metaprogramming AJUG_SEP2009 - 14

Groovy Goodies Overview • Fully object oriented • Closures: reusable and assignable pieces of code • Operators can be • GPath: efficient overloaded © ASERT 2006-2009 object navigation • Multimethods • GroovyBeans • Literal declaration for • grep and switch lists (arrays), maps, ranges and regular • Templates, builder, expressions swing, Ant, markup, XML, SQL, XML-RPC, Scriptom, Grails, tests, Mocks AJUG_SEP2009 - 15
