How to test and debug Timer triggered Azure functions running locally on localhost

With Azure function project type we may create many types of Azure functions. One of them is Timer triggered Azure function which is triggered by scheduler (CRON expression is specified during function creation and may be modified later in Azure function attribute):

When you will run this function locally (on locahost) you will notice thatt it won’t be listed under

http://localhost:7071/api/*

address together with Http triggered Azure function. Runtime will call your function automatically when schedule time will come. But this is not very convenient since during development you would probably like to have possibility to call it synchronously on demand.

In order to call Timer triggered Azure function you may use Postman tool. You have to construct URL little bit different from Http triggered functions: instead of /api you should send POST request to http://localhost:7071/admin/functions/* base url and send the following request body:

{
    "input": ""
}

Using this technique you may debug your Timer triggered Azure functions synchronously.
