check the whole release in a single assertion. It makes sure the test isn't missing some checks, and it consistent with the other loaders' tests.

Why not an equality? eg. assert requests_mock_datadir.request_history == ["https://repo1.maven.org/maven2/..."]

Because requests_mock_datadir.request_history is a requests_mock.request._RequestObjectProxy object that cannot be compared to a list.

It's ugly, though, so I've rewritten these lines for readability. Thanks.

borisbaldassari: Because `requests_mock_datadir.request_history` is a `requests_mock.request.

ping

(btw, the reason is that, if there is an extra item at the beginning of the list, pytest makes it obvious. with the current code, it only shows the items don't match)

This has been addressed in the lines below:

assert requests_mock_datadir.request_history[0].url == MVN_ARTIFACTS[1]["url"]
assert len(requests_mock_datadir.request_history) == 1

I don't know what I can improve there. As said above the equality just isn't possible as I cannot compare requests_mock.request._RequestObjectProxy to a list. But the second line ensures that equality is satisfied (and that there is no other item). Any idea?

Sorry to be annoying with this, but I'd really like the metadata to be the original POM instead of this custom dictionary format, that is missing most of the original metadata (<parent>, <dependencies>, etc.)

@vlorentz you're not annoying.
What is annoying though is the fact that some of my answers are lost (when rebasing I guess). :-)

Anyway, I've done as suggested.
