let recieved = 0;
let topic = 'gustavTest-listen';
let producer = new kafka.Producer(client);
producer.on('ready', () => {
producer.send([{
topic,
messages: ['hello']
}], handleErr);
});

kafObservable.subscribe(item => {
recieved++;
expect(item, 'Recieved proper message').to.equal('hello');
expect(recieved, 'Correct number of runs').to.equal(1);
done();
},
