OSGi Community Event 2013 (http://www.osgi.org/CommunityEvent2013/Schedule) ABSTRACT In order to meet software project requirements, it is important to implement ongoing quality assurance using automated tests. However, for OSGi platforms which are used in various areas such as Embedded or Enterprise this turns out to be difficult. If several components need to be tested together, unit tests written in Java tend to reach their limits. Thus, implementing these tests can be very time consuming. Using the Groovy language, OSGi integration tests are efficient and easy to write, e.g. registering Groovy mocks as a OSGi Service turns out to be very handy. Hereby declarative OSGi components can be tested, too. Even if an OSGi application has to be CDC-compliant, tests can be written using Groovy in a modern syntax. This presentation demonstrates how to implement Groovy tests for a sample OSGi project and how Groovy tests can be executed in an Equinox OSGi environment. Furthermore, it shows how a continuous integration solution using Maven Tycho can look like.

writing tests would make fun...

5. :1 NOITSEUQ
Do you test your OSGi
components?

6. : 2 NOITSEUQ
Are you using Groovy?

7. Our Testing Story
Embedded Device with CVM (~Java 1.4)
OSGi framework (Prosyst mBS)
Development with Eclipse
CI Build with Maven and Tycho

8. How to write our tests?

9. Test Requirements
Easy to write
Modern language
Type-safe access to Java classes
Easy mocking
Executable in Eclipse and Maven CI build
Good IDE support
No side effects for production code

10. V J
Modern language?
Not really...

12. What? Why Groovy?

13. Because we can!

14. YVOORG
JVM Language
Syntax Sugar
Closures
Less "Chatty"

15. Groovy JUnit Test
Type inference, readable asserts, syntax sugar and more:
@et
Ts
vi 'ul pzawt BQsueol'){
od Bid iz ih B ac ny(
dfpza=Pzaule.ePza)
e iz
izBidrnwiz(
.ihac(B)
wtSueBQ
.ul(

asrTa pzasue i(B)
setht iz.ac, sBQ
}

16. How to test our OSGi Services?

17. Pizza Service Sample
Services: PizzaService → PaymentService
pbi casPzaevcIp ipeet Pzaevc {

..

ceiCrPyetevc.adernato(.)
rdtadamnSriehnlTascin..;
..
.
}
}

18. STSET TINU
+Executed fast
+Focussed on the component
­No OSGi Runtime features
­Dependencies must be mocked
­No testing of declarative OSGi parts

19. STSET METSYS
+Cover complete system
+Real target environment
+No mocking or special configuration
­Embedded device is needed (high execution effort)
­Slow execution
­Not focussed

20. STSET RENI TNOC NI
Executed in OSGi environment
Focussed on the component
Testing of declarative OSGi parts
Only partial mocking

21. ...we can not run Groovy in CVM

22. Why not use
XONIUQE
with a modern JVM?

23. YVOORG
In-Container Testing with
equinox

24. Mocking
Simply transform a map to a proxy:
dfpyetevc =[
e amnSrie
hnlTascin {Srn cmayd ln ceiCrNme adernato:

asrTa cmayd i(qaT(LII_IZ_EVC')
