org.wisdom.test.parents.Stability

public class Stability
extends Object

Enhance the stability concepts from the OSGi Test Helpers with the a third check. With this class, stability is reached when:

1. all (non-fragment) bundles are resolved, and no bundle events are fired in a defined time period.
2. all iPOJO processing queue are empty.
3. no service event are fired in a defined period.

waitForStability

public static void waitForStability(org.osgi.framework.BundleContext context)
                             throws IllegalStateException

Waits for stability:

• all bundles are activated
• service count is stable

If the stability can't be reached after a specified time, the method throws a IllegalStateException.

Parameters:

context - the bundle context

Throws:

IllegalStateException - when the stability can't be reach after a several attempts.

waitForIPOJOQueuesToBeEmpty

private static void waitForIPOJOQueuesToBeEmpty(org.osgi.framework.BundleContext context)

areAllQueuesEmpty

private static boolean areAllQueuesEmpty(List<Object> queues)

Checks whether or not all the iPOJO processing queue are empty or not. Metrics are retrieved using reflection to avoid issues when iPOJO is in the classpath.

Parameters:

queues - the queues

Returns:

true if all the iPOJO processing queue are empty, false otherwise.

waitForServiceStability

private static void waitForServiceStability(org.osgi.framework.BundleContext context)

waitForBundleStability

public static void waitForBundleStability(org.osgi.framework.BundleContext context)

getBundleStability

public static boolean getBundleStability(org.osgi.framework.BundleContext bc)

Are bundle stables.

Parameters:

bc - the bundle context

Returns:

true if every bundles are activated.
