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?

• Wrong first question!

• Perfect second question?

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

The Landscape of JVM Languages

Java bytecode calls

for static types

Dynamic features call

for dynamic types

optional

static

types

The terms “Java Virtual Machine” and “JVM” mean a Virtual Machine for the Java™ platform.

import common

Better Lists, Maps, Ranges

• Lists– Special syntax for list literals

– 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

Driver Category• Real browser invoker

– Runs on platform

supported by real

browser

– May need multiple

platforms, e.g. IE6/IE7

– Uses actual JavaScript

engine

– 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

restrictions

– Good for CI

– Easier to not download

images, resources

– Ability to optimise

JavaScript interactions

– More extensible

– Ability to disable

JavaScript

– Scope for parallelism

• 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

– 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
