I noticed that the org.jboss.seam.mock.BaseSeamTest has some references to what it seems to be JBoss Embedded: import org.jboss.deployers.spi.DeploymentException; | import org.jboss.embedded.Bootstrap; | << snip >> | protected void startJbossEmbeddedIfNecessary() throws DeploymentException, IOException { | if ( !started ) { | Bootstrap bootstrap = Bootstrap.getInstance(); | bootstrap.bootstrap(); | << snip >> | } | } Is this intentional? As a result, SeamTest refuses to start (throws ClassNotFoundException) unless JBoss Embedded is present. When I removed the above method, SeamTest executed normally in a standalone environment, so there's no real dependency there.
