Smoke Test ML Pipeline
The minimal pytest that catches the "load → featurize → split" anti-pattern at iteration time, before it reaches production.
Stop conditions — read before anything else
- No smoke test without an approved design note + script. The pairing
rule from
test-ml-pipelineis hard:tests/smoke/test_NN_<short_name>.pyexists only whenjournal/NN_<short_name>.mdis at leastapprovedandexperiments/NN_<short_name>.pyexists with the matching stem. - Symbol from memory is forbidden. Any skrub /
scikit-learn name you write in the smoke test must come from a
Skill(python-api)/Skill(python-api)call in this turn. The smoke test is a small file but it imports the predicting-package API surface; the same memory-forbidden rule applies. - Don't shrink the assertion. The hard assertion is exact row-count equality. Not "approximately equal", not "at least 80% of expected rows". A row-count mismatch is the failure mode the smoke test exists to catch. Loosening the assertion silently reintroduces the bug.
- Don't synthesize the fixture. The smoke test reads the real
data/source. Synthetic fixtures look fine but skip the loaders that actually break in production. - No wrappers, no NaN-handling, no
eval_modehacks. If the smoke test only passes after wrapping the predictor or conditioning oneval_mode, the pipeline is wrong. Route back tobuild-ml-pipelineand fix the X-marker placement. Wrappers paper over the failure mode; they don't solve it. - The smoke test uses only the predicting package's API.

Do not importskore(or any other tracking / reporting library) in the test file.

Pre-flight — emit this checklist as visible text before any test code
Pre-flight (smoke-test-ml-pipeline):
- [ ] Tier 1 mandatory libs importable: pytest + sklearn + skrub
(per `data-science-python-stack` § "Tier 1"). **Not skore** —
see the Stop conditions; the smoke test is intentionally
portable to any skrub-capable environment
- [ ] Skill(python-api) consulted for skrub / sklearn symbols used in
the test: <symbols, or "none">
Evidence: Read scratch/api/<lib>/<version>/<topic>.md (this turn)
| Write scratch/api/<lib>/<version>/<topic>.md (this turn)
| "n/a — test only uses symbols already present in
src/<pkg>/ (build_learner / load_training_table / etc.)"
"Read python-api SKILL.md" alone is NOT evidence.
- [ ] `journal/NN_<short_name>.md` read this turn (frozen sections:
Question, Method) so the test asserts what the experiment claims
- [ ] `experiments/NN_<short_name>.py` skimmed this turn for the env-dict
keys `build_learner` consumes (`data_dir` / `start` + `end` /
`raw_frame` / etc.)
- [ ] `src/<pkg>/data.py` skimmed this turn for the loader signature
(so the predict-env construction matches the loader's expectations)
- [ ] Test category & stem decided: `tests/smoke/test_NN_<short_name>.py`
- [ ] Predict-grid size decided: smallest window that still triggers
the failure mode (default: a single horizon-length slice; for
time series, the most recent N steps such that the target is
*just* observable for assertion)
- [ ] Hard assertion wired: `len(predictions) == n_predict_grid_rows`
- [ ] Soft assertion wired (or explicitly skipped): smoke MAE within
`3 × CV_MEAN_HARDCODED_FROM_PLAN` (or task-appropriate
analogue). Value is a literal pulled from the matching
`journal/NN_<short_name>.md` § Status.headline; the test does
not import `skore` / read the project store at runtime.
What the smoke test asserts
Two assertions, two severities:
Hard — the row-count check
assert len(predictions) == n_predict_grid_rows
This is the structural-correctness assertion. It is a binary
pass/fail and it is the whole point of the smoke test. A
correctly built pipeline (per build-ml-pipeline's X-marker rule)
satisfies this trivially. A pipeline that loads-then-features-
then-splits will fail it because predict-time featurization on the
predict env runs with no pre-history buffer and silently drops
cold-start rows.
n_predict_grid_rows is the count of rows the predict env
claims to want predictions for — typically the number of
target-time rows in the predict-time grid. If the pipeline's
source binding is a directory of raw files, it's the row count of
the supervised frame derived from the predict env at predict time
(usable via build_supervised_frame(predict_dir)).
Soft — the metric-vs-CV gap
smoke_mae = mean_absolute_error(y_true, predictions)
assert smoke_mae < 3 * cv_mae_mean, (
f"smoke MAE {smoke_mae:.0f} is more than 3× the CV mean "
f"({cv_mae_mean:.0f}); predictions may be NaN-poisoned even "
f"though the count matches."
)
The metric gap catches the second-order failure mode: the
prediction count is right, but the values are garbage because some
features are NaN at predict time (e.g. an encoder hasn't seen a
new category, a lag is null because the upstream history reference
wasn't wired correctly). The 3× bound is a starting heuristic;
adjust per task. The smoke window is a single seasonal slice, so
the bound has to be loose enough that a legitimate hard-season
window doesn't trip it.
The soft assertion is opt-out, not opt-in: skip it only if the task has no obvious metric-vs-CV comparator (e.g. the smoke fixture deliberately has no ground truth). If you skip it, leave a comment on why in the test file.
The diagnostic-by-construction property
The fixture is built specifically to fail on the buggy shape and pass on the correct one. This is the single most important property of the smoke test; if you take the fixture construction shortcut and it doesn't have this property, the test is worthless.
Concretely, the predict-time env-dict carries only the rows we want predictions for, with no pre-history buffer beyond what predict-time-known features absolutely require. Two consequences:
- Late-
mark_as_Xpipeline: features are computed inside the graph from the predict env's data alone. Backward lags / rolling windows / target shifts have NaN at the cold-start rows. The pre-markerdrop_nulls(or the model's NaN intolerance) drops those rows.len(predictions) < n_predict_grid_rows. Test fails. - Early-
mark_as_Xpipeline: the marker lands on the predict-grid node (Layer 2 ofbuild-ml-pipeline's rule 2); history-dependent features take the upstream history DataOp as an additionalapply_funcargument. At predict time, the history node resolves to the full available history (bound from the same source the train env uses), and the join in each feature step produces real values for every row in the predict grid.len(predictions) == n_predict_grid_rows. Test passes.
The two outcomes are deterministic. The smoke test cannot be "flaky" — if the row count is off by one, the pipeline is wrong.
For the predict-grid size: smallest is best. Use the smallest predict window that is still an honest predict-time grid. A single horizon-length slice (e.g. one day for a t+24 model) is enough to expose the failure; anything larger only hides it behind volume.
Fixture construction — data/ is the source
The fixture reads from the real data/ source, not from a
synthetic generator and not from a checked-in fixture file. The
loaders the experiment uses are the loaders the smoke test must
exercise. Synthetic fixtures defeat the purpose.
Construction depends on the experiment's source binding (read
experiments/NN_*.py to find out which env-dict keys
build_learner consumes), but the shape is always the same:
- Identify the predict-grid time bounds (
predict_start,predict_end). For time series, the most recent horizon-equivalent window of the data. - Identify the train env. The cleanest choice is all data
strictly before
predict_start - HORIZON(embargo equal to the forecast horizon). For tabular IID, just exclude the rows in the predict grid. - Build two env-dicts:
train_env: whatever shape the experiment uses for its fit binding, restricted to data before the embargo.predict_env: the predict-grid description, with no additional history padding (this is the diagnostic property; if you pad, the test passes spuriously).
- Compute
n_predict_grid_rowsindependently of the prediction — the count comes from the supervised representation of the predict env (not from the prediction itself). - Compute
y_truefrom the supervised representation of the predict env (the soft assertion's ground truth).
The fixture must not write derived files to data/holdout/,
data/train/, etc. Those are workspace-level artifa

# Smoke Test ML Pipeline
The minimal pytest that catches the "load → featurize → split"
anti-pattern at iteration time, before it reaches production.
## Stop conditions — read before anything else
- **No smoke test without an approved design note + script.** The pairing
rule from `test-ml-pipeline` is hard:
`tests/smoke/test_NN_<short_name>.py` exists only when
`journal/NN_<short_name>.md` is at least `approved` *and*
`experiments/NN_<short_name>.py` exists with the matching stem.
- **Symbol from memory is forbidden.** Any skrub /
scikit-learn name you write in the smoke test must come from a
`Skill(python-api)` / `Skill(python-api)` call **in this
turn**. The smoke test is a small file but it imports the
predicting-package API surface; the same memory-forbidden rule
applies.
- **Don't shrink the assertion.** The hard assertion is exact
row-count equality. Not "approximately equal", not "at least 80%
of expected rows". A row-count mismatch *is* the failure mode the
smoke test exists to catch. Loosening the assertion silently
reintroduces the bug.
- **Don't synthesize the fixture.** The smoke test reads the real
`data/` source. Synthetic fixtures look fine but skip the
loaders that actually break in production.
- **No wrappers, no NaN-handling, no `eval_mode` hacks.** If the
smoke test only passes after wrapping the predictor or
conditioning on `eval_mode`, the pipeline is wrong. Route back
to `build-ml-pipeline` and fix the X-marker placement.
Wrappers paper over the failure mode; they don't solve it.
- **The smoke test uses *only* the predicting package's API.**
For a `SkrubLearner` produced by `build-ml-pipeline` that means
skrub's `fit` / `predict` / (optionally `score`) plus
`sklearn.metrics` for any metric the soft assertion uses.
**Do not import `skore`** (or any other tracking / reporting
library) in the test file. The smoke test must be runnable in
any environment that can `import skrub` + `import sklearn` —
the skore Project is a side artifact, not a test dependency.
Soft-assertion baselines (CV-mean MAE, etc.) are **hardcoded
from the design note's Status.headline** with a comment pointing to
the design note; update by hand when the experiment's headline number
changes.
- **Don't filter warnings.** No
`@pytest.mark.filterwarnings(...)`, no
`warnings.filterwarnings(...)` in the test body, no
`filterwarnings = [...]` in `pytest.ini` /
`pyproject.toml` — unless the user explicitly asks. See

## What the smoke test asserts
Two assertions, two severities:

This is the *structural-correctness* assertion. It is a binary

satisfies this trivially. A pipeline that loads-then-features-

`n_predict_grid_rows` is the count of rows the predict env

source binding is a directory of raw files, it's the row count of
the supervised frame derived from the predict env at predict time

### Soft — the metric-vs-CV gap
```python

f"smoke MAE {smoke_mae:.0f} is more than 3× the CV mean "
f"({cv_mae_mean:.0f}); predictions may be NaN-poisoned even "

)
```
