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.
Topics not covered in detail
• Coverage– But coverage options available
• Mocking– But built-in support and many libraries available
• CI Support– Support in Hudson, Team City, Anthill Pro to call
Groovy
• Code Metrics– CodeNarc and other tools available
• Build Tools– Ant, Maven, GMaven, Gant, Gradle, ...

Why Test With Groovy?

organization and people fit!Agile2009 - 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
– Expected feedback from tests (JUnit/Reports)
• Organization– Maturity level
– Degree of automation
– Tools in use
– Need for adaptability

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
– 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

Scripting/Dynamic Languages
• Advantages– Lend themselves to succinct code/DSLs
– Powerful
– Increased Refactoring
– Increased Reuse
– Less prone to Brittleness
– 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)

Test Characteristics• Coverage/Traceability
– Requirement coverage/traceability
– Code coverage: line, branch, path, state
– Transactional Tracing
• Purpose– Unit, Integration, System, Customer
• Manageability– Removing duplication
– 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

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
– 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

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.”
Groovy = Java – boiler plate code+ optional dynamic typing+ closures+ domain specific languages+ builders+ metaprogramming

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

Better Lists, Maps, Ranges

– Additional common methods (operator overloading)
• Maps– Special syntax for map literals
– Additional common methods
• Ranges– Special syntax for various kinds of ranges

Closures
• Traditional mainstream languages– Data can be stored in variables, passed around,
combined in structured ways to form more complex
data; code stays put where it is defined
• Languages supporting closures– Data and code can be stored in variables, passed
around, combined in structured ways to form more
complex algorithms and data

– May need multiple

– Uses actual JavaScript

– Can be easier to use
with test recorders
– Automation
capabilities differ
across browsers
– Can typically get to all
aspects of browser
• Browser Emulators
– Can simulate multiple
browsers
– Less platform

– Good for CI
– Easier to not download
images, resources
– Ability to optimise
JavaScript interactions
– More extensible
– Ability to disable

– Scope for parallelism

WebDriver
• Description– Simple API to drive both real browsers
• for testing javascript heavy apps
– and a pure 'in memory' emulator solution
• for faster testing of simpler apps
• uses HtmlUnit under the covers in emulator mode
– Represents next generation of Selenium RC
• though merging into Selenium may happen under the covers
if you are a Selenium user
– Roadmap has plans to leverage some advanced
Selenium like features
• RemoteWebDriver

Tellurium
• Description– built on top of Selenium but tries to solve several
shortcomings
– "record and reply" style, difficult to refactor and
maintain, so instead define UI components
declaratively then write tests in terms of UI
– Provides many predefined UI objects for you to use
directly, such as Button, CheckBox, InputBox,
Selector, TextBox, and Table but also ability to write
your own custom UI objects
– Supports advanced locating mechanisms: composite
locator, "group locating"
– Supports testing DSL
– Supports data-driven tests

JWebUnit...
• Description– Java-based testing framework for web applications
– Intention is to provide a high-level "driver" Java API
– Wraps existing testing frameworks such as HtmlUnit
and Selenium with a unified, simple testing interface
– Support includes navigation via links, form entry and
submission, validation of table contents, and other
verification steps
– Includes some runner capabilities
– Useful in that it allows you to switch between
different lower level drivers without re-writing your
tests

Native Groovy
• Groovy has a friendly ‘==‘
• Built-in assert
• Scripts are low ceremony
• By utilising @Grab are easy to share
• Many in-built testing capabilities are
accessible even from scripts
• Easy to version control or treat like
operating system scripts
• Out of the box detection of JUnit and
TestNG tests

JBehave
• Description– Behaviour-driven development in Java
• Also works out of the box for Groovy
– Behavior scenarios written in text
• Use the words Given, When, Then and And.
– Mapped using regular expressions and annotations
to step methods
– Web Runner available for non-technical users to
easily run tests
– Hooks to Selenium available in JBehave Web
• Other Java libraries (e.g. HtmlUnit) easy to use too
– Supports parameter converters
• Getting 'String' parameters into appropriate Object values
– Supports a 'StepDoc' function
• For listing available scenario clausesAgile2009 - 118
