1. Test Driven Development with OSGi focuses on reducing deployment time through the use of OSGi and maven plugins to allow for faster iteration. 2. The eosgi-maven-plugin is demonstrated which allows defining OSGi container environments and running integration tests directly from maven. 3. The plugin supports configuring JVM options, system properties, timeouts and more to customize the container environment for running tests.

1. Test Driven Development with OSGi
Balázs Zsoldos

2. Original motivation
Deployment time
2 minutes
Internet time
10 minutes

3. Coding time
Deployment time
Facebook time
“What was I doing?” time

4. Reduce
deployment
time
v3

5. “mvn package”
+
copy file
Iteration is faster, but not fast enough (compile + copy)

6. drop JAR
OR
Drop project
process
“target/classes”

7. Eclipse
+
maven-bundle-plugin
=
up-to-date “target/classes”

8. Richconsole deployment
OSGi container
StartLevel 10
Bundle A (startLevel=4)
Bundle B (startLevel=2)
A
StartLevel 2
B

9. Deployment time reduced
How can we have better quality?

11. The Three Laws of TDD
1.You are not allowed to write any production code until you have
2.You are not allowed to write more of a unit test than is sufficient
3.You are not allowed to write more production code that is suffici
The Clean Coder (Chapter 5)

12. External Blockers
External Test Engines
Framework Startup
Blocker
Blueprint
Blocker
JUnit4
TestEngine
Test runner

13. Blueprint / DS / creation from Acvtivator / ...
Test service
service.id=MyTest
service.testEngine=junit4
Test runner
JUnit4
TestEngine

14. I do not want to re-run all tests during
development
In development mode only tests with
@TestMethodInDevelopmentMode or
@TestClassInDevelopmentMode runs.

15. Test Code
Deploy / Run tests
Production code

16. Test Code
Deploy / Run tests
Production code
What will run the tests on Jenkins?

17. Maven repository
Get the dist package

- Unpack dist package
- Parse with velocity
- Add the dependencies

18. Maven repository
Get the dist package
eosgi-maven-plugin:integration-test
- Unpack dist package
- Parse with velocity
- Add the dependencies
- with testrunner
- as symbolic links

23. 100% coverage

24. Let's see it in practice

25. Creating your own dist package
●
Look at the sample equinox package
●
Look at the .eosgi.dist.xml file
Look for the XSD in eosgi-maven-plugin sources and
read the documentation
●
●
Velocity variables
– .eosgi.dist.xml
●
●
bundleArtifacts:
List<DistributableBundleArtifact>
environment: EnvironmentConfiguration
– Parseable
files
