Just have a dedicated queue for debugging and send a message to that queue – Gel

Just launch your runtime as you'd for http, then put the message on the queue. It should trigger your function even locally. If the queue is shared with your Azure instances it may be a race condition depending on who grabs the message first, so you may wanna have a test queue – Legator

If you'd like to test/debug your Azure functions app against the storage queue locally, without using Azure storage account, you can install the Microsoft Azure storage emulator that provides a local environment that emulates the Azure Blob, Queue, and Table services for development. purposes.

edit:

As my function was deployed on the Azure, so the message from the queue from getting consummated by the functions running on AZURE

Your WebJob on Azure and local consume message from same storage account, if you want only local WebJob function is triggered, as you said, you can disable your WebJob on Azure. Besides, as I mentioned, for testing/debuging your Azure WebJob functions locally, you can use Microsoft Azure storage emulator.

Hi , its not about not using storage account. its about how to trigger the queuetrigger locally while debugging the azure function on my visual studio. – Penitence

Hi Thanks , its done. As my function was deployed on the Azure , so the message from the queue from getting consummated by the functions runing on AZURE. I disabled the function on azure and debugged locally and the message was started to come into my debug window. – Penitence
