Our Journey – The Beginning
Releases withManual testing
Prototype
Quality is notthe main focus
Long QA Cycles,Stress
● We have:
– Unit tests
– Automated by the CIServer
● We need:
– Automated acceptancetests
– Created by thedevelopment team

Automate UI Tests with SWTBot
● SWTBot: @Eclipse
– Write UI Tests with a beautiful Java API
– Integrates with JUnit, Tycho (Maven)
– Eclipse integrated Test Recorder for bootstrapping

Our Journey – Strong Coupling

Tests are onlyreadable forDevelopers
● We have:
– Strong coupling ofspecification andimplementation oftests
● We need:
– Loose coupling
– Human readable testspecifications
– Still maintained bydevelopers

Define Features with Cucumber
● Cucumber: cukes.info
– BDD framework
– Feature specifications written in textual form
– Specification steps implemented in a programminglanguage
– Ports available for many languages: Ruby, Java,Javascript … etc.

Define Features with Cucumber (2)● Gherkin language:
– Easy to understand fornon-developers
– Separatesimplementation details
Step defnitions in plain Java

Sidebar: Jnario
● Jnario is an alternative to Cucumber
● Create executable specifications for
– Unit and integration tests
– Acceptance tests
● Built on Xtend
● Great tooling Check it out at: jnario.org

Mixing SWTBot with Cucumber
● Created an SWTBot runner for Cucumber
● Can be executed from Eclipse with the standardJUnit launcher
● Also works with Maven and Tycho
Acceptance Tests

Caveat: Hands Off while Running Tests
● Running SWTBot tests is sensitiveto external input events by theuser
– e.g. tests can fail if the testedwindow loses focus
Workaround: Run tests in a VM without
automatic input capture

Caveat: Test Execution Time
● We are simulating a real usageenvironment
– Executing test suites can takea long time
Workaround: Developers only run affected features
Full test suite executed by the CI server

Spicing the build with Tycho
● Project currently in Eclipse Incubation
● Build and test Eclipse Plugins on the commandline with Maven
● The glue between the PDE and CI servers
Our Pluginis ready

Mr. Jenkins will serve the results
● Use Jenkins CI
– Launch builds with Maven (and Tycho)
– Inspect the results of tests
