The same way any other message is created by an application.

Well that depends on both the sending and the consuming application.

That depends entirely on what makes them poisonous.

That depends entirely on what makes them poisonous.

Please consider doing some research on your own before asking these very, very basic questions.

I repeat the advice given to you here on the importance of setting up back out queue(s) to handle poison messages and other problems.

Sorry, If i have repeated the question. I actually wanted to create those poison messages and test if for error conditions. Also, I want to test DLQ conditions. I want to know do we performance test all the known error scenarios when setting up backout Q and DeadLQ in previous environment before setting the same configuration for Production environment.

You should thoroughly performance test the happy path. You should also throw in a few errors to see how they affect the happy path.

In your Unit test, you should do a full coverage test and test all possible errors.

Have fun
