Example 85 with BundleException

use of org.osgi.framework.BundleException in project sling by apache.

the class LogSupportTest method testFrameworkEventError.

@Test
public void testFrameworkEventError() throws Exception {
    BundleException bundleException = new BundleException("my bundle exception", BundleException.ACTIVATOR_ERROR);
    FrameworkEvent frameworkEvent = new FrameworkEvent(FrameworkEvent.ERROR, bundle, bundleException);
    logSupport.frameworkEvent(frameworkEvent);
    Mockito.verify(testLogger).error("FrameworkEvent ERROR (org.osgi.framework.BundleException: my bundle exception)", bundleException);
