The easiest way to do this is to either use the workbench at developerforce.com or the developer console. I'm going to use the developer console.

If the Push Topic is executed successfully then Salesforce is ready to post notification to MULE ESB if any changes made in the Account object in Salesforce, because the below Push Topic has been created for Salesforce’s Account object.
