I have a question, and I think it mostly comes from me having a stronger Python background than Ruby. I have the following couple of files - but we parallelize our tests, and so I think that each spec file is trying to separately spin up pact servers, so I get errors that the address is already in use. Is there any accepted way to handle this?

I tried wrapping the set up in a

shared_context

, but the setup for the shared context gets run each time it’s included. I could just randomize the port every time, but that doesn’t seem like the right move

You’d really need to know what you were doing to get pact running parallel.

Each different process would need it’s own mock server

The mock server is stateful.

Gotcha - this makes sense

You could use this gem to find a free port https://rubygems.org/gems/find_a_port/versions/1.0.1

you’d also need to set the pact file write mode to “merge”

and wipe it before the test suite starts

if you dynamically set a port on the mock server, you can use

<your_service>.mock_service_base_url

to get the base URL to send the requests to.
