[rabbitmq-discuss] PRECONDITION_FAILED question

Tue Nov 12 17:01:34 GMT 2013

Hi!
I'm writing unit tests for my C# RabbitMq component over RabbitMq client
library.
My code like this:

public void RemoveExchange(string name)
{
  _channel.ExchangeDelete(name, true);
}

When I'm using it in my units, like

try
{
  RemoveExchange("x-declared-before-exchange-and-binded-to-any-queue");
}
catch (Exception e)
{
  /* here I get:
The AMQP operation was interrupted: AMQP close-reason, initiated by Peer,
code=406, text="PRECONDITION_FAILED - exchange 'exchange-name' in vhost '/'
in use", classId=40, methodId=20, cause=
  */
}

It is ok, because my exchange is in use. But when I tried later to use
_channel.QueueUnbind command I get the same exception.

Please advise, how to avoid this. Thanks.
