From Objects to Functions: (B7.0) Different error message on page 33
In our first acceptance test we expect according to page 33 “An operation is not implemented: parse the response” - in fact we receive “HTTP/1.1 503 Client Error: Connection Refused caused by Failed to connect to localhost/[0:0:0:0:0:0:0:1]:8081” because we don’t start the server so far in our acceptance tests.
