It might help to create a test utility at `oae-tickets/lib/test/util` with an exported function
```javascript
/**
 * ..
 * @throws {Error}
*/
var assertTicket = module.exports.assertTicket = function(ticket, ticketId, externalId, publicationId, tenantAlias, status) {
    assert.strictEqual(ticket.ticketId, ticketId);
....
    assert.strictEqual(ticket.status, status);
}
```
