When a wizard is executed, the postCommandExecuted is called for each step in the Wizard. This leads to the invocation of org.jboss.forge.addon.shell.test.impl.DefaultShellTest.TestCommandListener.postCommandExecuted(UICommand, UIExecutionContext, Result) several times.

The org.jboss.forge.addon.shell.test.impl.DefaultShellTest.TestCommandListener.isExecuted() method should be reviewed, since the current impl may return true even if the command has not finished execution
