OSGi Container integration

Arquillian OSGi Container

The Arquillian OSGi Container provides Arquillian testing in OSGi frameworks.

Maven Setup

For the JBOSGi Framework setup the following dependencies

<dependencies>
    <dependency>
        <groupId>org.jboss.arquillian.container</groupId>
        <artifactId>arquillian-osgi-embedded</artifactId>
    </dependency>
    <dependency>
        <groupId>org.jboss.osgi.framework</groupId>
        <artifactId>jbosgi-framework-core</artifactId>
    </dependency>
</dependencies>

for Apache Felix setup these

<dependencies>
    <dependency>
        <groupId>org.jboss.arquillian.container</groupId>
        <artifactId>arquillian-osgi-felix</artifactId>
    </dependency>
    <dependency>
        <groupId>org.apache.felix</groupId>
        <artifactId>org.apache.felix.framework</artifactId>
    </dependency>
    <dependency>
        <groupId>org.apache.felix</groupId>
        <artifactId>org.apache.felix.main</artifactId>
    </dependency>
</dependencies>

The arquillian.xml resource references the framework configuration file

<arquillian xmlns="http://jboss.org/schema/arquillian" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://jboss.org/schema/arquillian http://jboss.org/schema/arquillian/arquillian_1_0.xsd">

	<container qualifier="jboss" default="true">
		<configuration>
            <property name="frameworkProperties">src/test/resources/jbosgi-framework.properties</property>
		</configuration>
	</container>
</arquillian>

which is in standard properties format

# Properties to configure the Framework
org.osgi.framework.storage=./target/osgi-store
org.osgi.framework.storage.clean=onFirstInit

# Extra System Packages
org.osgi.framework.system.packages.extra=\
	org.jboss.logging;version=3.0,\
    org.slf4j;version=1.6

# Bundles that need to be installed with the Framework automatically 
#org.jboss.osgi.auto.install=\

# Bundles that need to be started automatically 
org.jboss.osgi.auto.start=\
	file://${test.archive.directory}/bundles/org.apache.felix.log.jar,\
	file://${test.archive.directory}/bundles/jboss-osgi-logging.jar,\
	file://${test.archive.directory}/bundles/jbosgi-repository-bundle.jar,\
	file://${test.archive.directory}/bundles/jbosgi-provision-bundle.jar

Arquillian OSGi Tests

A simple test case looks like this

@RunWith(Arquillian.class)
public class SimpleBundleTestCase {

    @ArquillianResource
    BundleContext context;

    @Deployment
    public static JavaArchive createdeployment() {
        final JavaArchive archive = ShrinkWrap.create(JavaArchive.class, "test.jar");
        archive.setManifest(new Asset() {
            public InputStream openStream() {
                OSGiManifestBuilder builder = OSGiManifestBuilder.newInstance();
                builder.addBundleSymbolicName(archive.getName());
                builder.addBundleManifestVersion(2);
                builder.addImportPackages(Bundle.class);
                return builder.openStream();
            }
        });
        return archive;
    }

    @Test
    public void testBundleContextInjection() throws Exception {
        assertNotNull("BundleContext injected", context);
        assertEquals("System Bundle ID", 0, context.getBundle().getBundleId());
    }
    
    @Test
    public void testBundleInjection(@ArquillianResource Bundle bundle) throws Exception {
        // Assert that the bundle is injected
        assertNotNull("Bundle injected", bundle);

        // Assert that the bundle is in state RESOLVED
        // Note when the test bundle contains the test case it
        // must be resolved already when this test method is called
        assertEquals("Bundle RESOLVED", Bundle.RESOLVED, bundle.getState());

        // Start the bundle
        bundle.start();
        assertEquals("Bundle ACTIVE", Bundle.ACTIVE, bundle.getState());

        // Assert the bundle context
        BundleContext context = bundle.getBundleContext();
        assertNotNull("BundleContext available", context);

        // Stop the bundle
        bundle.stop();
        assertEquals("Bundle RESOLVED", Bundle.RESOLVED, bundle.getState());
    }
}
