quick look 1

I added some comments in the PR
🙌 1
are there any concrete things that are unclear to you, that we could fix faster in a chat here?
j
@mashehu I'm getting a NullPointerException in the snapshot matching. The test creates vcontact3_output/ with CSV files but the snapshot might not match. Should I delete the snapshot and let it regenerate?
m
how are you generating the snapshot? because it looks like the problems is not the snapshot matching, but that the module doesn't run
j
The process crashes with NullPointerException during stub execution. Should I simplify the test to just assert 
process.success
without snapshot matching first, then we can debug the actual stub?
m
the problem is that you will not get a process.success either, because the module fails before that https://github.com/nf-core/modules/actions/runs/28516871248/job/84530912250?pr=12198#step:6:692

@mashehu All tests pass now without the snapshot assertion! Should I add snapshot testing back to the module? Or is just asserting process.success enough for nf-core standards?
m
not really. we would prefer to not have just a stub run, but an actual test of the tool and in the stub run to check that the outputs are as expected.
j
@mashehu Perfect! I understand now. I'm adding two tests: 1. Stub test - Runs in stub mode with 
-stub
option and checks snapshot of outputs to verify the structure 2. Real test - Actually runs vcontact3 with test data and verifies the output directory exists This way we test both the mock behavior and the real tool execution. Pushing now!
Hey ! Found the root cause of the vcontact3/run real-test failure. Traceback shows 
vcontact3 run
needs either 
-d/--db-path
or 
--db-version
— without one, 
databases.py
calls 
db_path.is_dir()
on 
None
and crashes with 
AttributeError: 'NoneType' object has no attribute 'is_dir'
. Confirmed on conda/docker/singularity, same error every time. Digging into the nf-core test-data guidelines, this looks like the same situation gtdbtk/classify hit — a tool that needs a local reference database too large for CI. The docs explicitly recommend stub-only testing for that case and point to gtdbtk/classify as the reference pattern. Given vcontact3's database is in the same boat, I'd propose dropping the 'real' test and following the gtdbtk/classify precedent (stub test only). I know you asked for a real test in an earlier review round, so wanted to check with you first rather than just changing it. Alternatively I could try 
--db-version
to auto-fetch a database in CI, but that risks a slow/fragile download each run. Let me know which way you'd like to go, or if there's already a minimal vcontact3 test database in test-datasets I'm missing.

@Jimit Patel I already responded when you commented on the issue - I suggested you look into finishing the upstream downloaddb module soemoen else started
GTDB is stub only because the database is 140GB
Also may I ask if you are using an LLM for your responses here on slack?
j
yes, I've been using an LLM (Claude) to help me draft some of my messages and dig through docs/research while working on this PR. I should have said that upfront rather than you having to ask, that's on me. On the issue — I missed your earlier comment about the downloaddb module before I re-asked here, sorry for the duplicate ask. I'm going to go read that comment and look at the module now before I come back with anything else.

Please do not send messages back to the channel, let's keep it in theead. You already have top maintainers helping you, let's avoid spamming everyone here

Hey — quick check: is the direction I'm taking things in okay so far? Root-caused the docker/singularity failures (missing curl dep, fixed upstream in bioconda-recipes#66829, now merged) and opened a fix PR for the review items on #11738. Wanted to confirm this is useful before I keep going, rather than assume.
m
Are you working on https://github.com/nf-core/modules/pull/11738 or https://github.com/nf-core/modules/pull/12198? I thought this thread was for 12198, so sorry if I'm getting confused
j
Good catch, sorry for the confusion — this thread started around #12198 (vcontact3/run), but the real blocker for that one turned out to be #11738 (vcontact3/prepareddatabases) — #12198 needs a database, and #11738 is the module that provides it, so I ended up working on both. Status: - #11738: root-caused the docker/singularity test failures (missing curl dependency in the vcontact3 bioconda recipe), fixed upstream (bioconda-recipes#66829, merged), and opened olawal1001/modules#1 with the remaining review fixes (versions.yml, meta.yml TODOs, test simplification). - #12198: paused until #11738 is in good shape, since it depends on the database module working. Happy to keep this thread focused on whichever one makes sense, or split it — whatever's easiest for you all to track.
m
For me you can only fix 11738 by updating the dependency that was fixed upstream. Until this is done, nothing can really be worked on
j
Got it, thanks — focusing on that. Will check when the new vcontact3 build (with curl) is live on Quay.io, update the container reference in #11738, and confirm docker/singularity tests pass before touching anything else.
