Is it a good practice to use use the same httptest server for multiple methods

I am trying to test some golang code and I have a method that calls several other methods from its body. All these methods perform some kind of operations using an elastic search client. I wanted to know whether it will be a good practice if I used a test server for testing this method that will write different responses depending upon the request method and path it received from the request that is made when the methods inside the body execute and make calls to the elasticsearch client that sends the requests to my test server?
