Hey! Sorry if this is a somewhat novice question, but I'm very new to JS/TS and trying to help another team out: We are using axios to perform REST requests in our client classes, and the base_url is populated via an import from another module that handles environment variables (as constants). So what's the best way to change the base_url to point at the pact mock server?

Depends on your test library. With jest you can mock the import. See the jest docs for more

Okay thanks! We are in fact using Jest, so it sounds like I just need to dive into Jest a bit more
