spring based unit test build with tycho?

[lfischer]

Hello,

I would like to migrate the build of a Spring Dynamic Modules project to maven3 with sonatype tycho.

The project contains multiple OSGi bundles. Within every bundle exists a fragment with unit test classes and spring test configurations. With tycho, now these tests are failing.

The test classes look like this:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "/META-INF/context.xml" })
public class ExampleTest {
[...]

Trying to run the tests with maven + tycho, I get this error:

Running ExampleTest
Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 0 sec
<<< FAILURE!
initializationError(ExampleTest) Time elapsed: 0 sec <<< ERROR!

Where is my mistake? Is there a solution, how I can run spring based unit tests with tycho?

Regards,
Lars

Judging from the stacktrace you are using a wrong version (< 4.7) of JUnit... Make sure you use a 4.7 version of JUnit and also configure other plugins to use this... Else you will/might run into these issues.

Hello Marten

Judging from the stacktrace you are using a wrong version (< 4.7) of JUnit... Make sure you use a 4.7 version of JUnit and also configure other plugins to use this... Else you will/might run into these issues.

Thank you for your hint. I now use the bundle org.junit4 version 4.8.1 from the helios update.
But now I get NoClassFoundExceptions for the bean declared in the spring configuration inside the tests fragment.


Lets say I have a "core" bundle and a depending "second" bundle.

There is also a "second.tests" fragment containing spring based unit tests. The spring context has beans with classes from the "core" bundle.

Do I have to extend AbstractConfigurableBundleCreatorTests as described in the SpringDM Reference Guide or is it sufficient just to use the "core" bundle as required bundle of the "second" bundle?

Sonatype Tycho brings its own maven-osgi-test-plugin for running unit tests in an osgi environment. Is someone else here using sonatype tycho with spring DM and could tell me how to setup the unit tests?

Regards,
Lars
