How can I test the total delay between my code placing an order and it being placed

So I want test the total delay between my code placing an order and it being placed on Binance and I don’t really know how to go about it I’m using JavaScript, but other code snippets or explanations would be create since I couldn’t find a way to check this. I gad one idea placing a test order or a fake order to place to check the delay between my code and it being placed, but I wasn’t able to do so and only being able to place real orders which I do not want.
