vcr demo

Hey @stitam, I used vcr for tests in another project and have a decent handle on how it works. Are we still interested in implementing it for testing webchem? The downside is that changes to APIs won't cause our tests to fail (unless we keep some tests that query the API).

Hi @Aariq, it takes forever to pass all the checks before merging a PR so I think vcr would be useful. To manage the downside, do you think e.g. manually rebuilding the vcr records every now and then would be feasible? I doubt this "every now and then" could be automated :/

there is also {httptest} , alternatively. It's more actively maintained, and if you were to switch to httr2, switching your tests to {httptest2} would be easier than from {vcr} to {httptest2}.

[Aariq]

Maybe I'll try out httptest for my other, simpler, project and report back.
