commit 40950aedd630c874cfefdfeffe14fc3f56c0e786
Author: Andres Ezequiel Viso <aeviso@softwareheritage.org>
Date:   Tue Sep 28 10:01:43 2021 +0200

    Add tests for conflict resolution functions

commit 5f1d1b13504ee534f3726a8002d7d3a4609ac1c3
Author: Andres Ezequiel Viso <aeviso@softwareheritage.org>
Date:   Tue Sep 21 16:13:53 2021 +0200

    Add support for remote backend on existing storage tests

commit 84a62793d5de0b51aa7706b04a773366f5411391
Author: Andres Ezequiel Viso <aeviso@softwareheritage.org>
Date:   Fri Aug 20 12:21:27 2021 +0200

    Add new RabbitMQ-based client/server API
    
    Write methods in the `ProvenanceStorageInterface` are called through a server that
    guarantees conflict-free writings to the underlying database.
    
    Read methods are called directly from the client to avoid RCP overhead for reads.
    
    The server spawns multiple sub-processes to handle independent requests concurrently.

See https://jenkins.softwareheritage.org/job/DPROV/job/tests-on-diff/498/ for more details.

Fine for me; these tests could be written as parametrized tests (https://docs.pytest.org/en/6.2.x/parametrize.html#parametrize-basics) but not a big deal.

This revision is now accepted and ready to land.Nov 29 2021, 10:04 AM

When I did so with other tests your claim was that they were too difficult to follow and that tests should be as explicit as possible. These ones have a declarative function name for each case. What's the criteria after all?

I don't know why you are talking about this. I am talking about something like this:

DATE = datetime.fromtimestamp(1000000000)
ONE_SEC = timedelta(seconds=1)
HASH = b"20329687bb9c1231a7e05afe86160343ad49b494"
RESOLVED_DATES = [
    (((HASH, ), (HASH, DATE), (HASH, None)), {HASH: DATE}),
    ((HASH, DATE), (HASH, DATE+ONE_SEC)), {HASH: DATE}),
]
@pytest.mark.parametrize("input,expected", RESOLVED_DATES) 
def test_resolve_dates() -> None:
    assert resolve_dates(input) == expected

I believe we can agree that this is not difficult to follow and read.

Also note that I accepted this diff, so I really don't understand what you are looking for with this...

def test_resolve_dates() -> None:

I believe we can agree that this is not difficult to follow and read.

I've never said this is difficult to read. Actually that's more in line to the previous test that I've originally submitted (for other methods) and I then I had to write in a more "explicit" on demand.

Also note that I accepted this diff, so I really don't understand what you are looking for with this...

What am I looking for? Simple, I'm trying to understand what the criteria are, to avoid having to rework the same stuff over and over again.
For now I'll stay with the more "explicit" form as that's what we've agreed before and I have several other test in the same style.
