How to check if a request was sent to an external service?

Question

Ruby on Rails

Hello.
There is a function that sends an alert to an external service. How can you check in an rspec test that this function has been called? Naturally, I can change the body of the function, the actual sending of the notification is already turned off by checking for Rails.env.test?
Thanks in advance.
