IFTTT Triggers without sensor when I click on Test

When I clicked on channel in my IFTTT login for the IFTTT key. When I clicked on ‘how to trigger event or on the code’ it was showing the following page

After that, when I clicked on ‘test it’, its showing that ‘the event has been triggered’, immediately im getting the email to my mail Id regarding the event name and time,which is used to done after submitting the key, pin and all when the sensor trigger an event, but im getting an mail before the sensor is triggered by any obstacle.

It will also work when you run it with a sensor. When you click on ‘Test It’. It checks for the same over the IFTTT server.
