Is there a way to cache DOI lookups in the test suite

[Kypore1]

As is it takes a long time to validate all the files because it has to download them all each time. Could we look into adding something to cache the files?

We did start to look at why the test suite is so slow in #86

Indeed, and @Kypore1 was running the code from before the commits that fixed #86. Let's see if the speed improves after updating to master. I still think this might be a good idea though... we can download JSON files of the message response or something in a directory that can be "cleaned" with a separate command

Sure, maybe we can set up a list of all the queries for the tests and do it all in one?
