test(e2e): skip dbconnect notebook tests - #2022
Merged

Conversation
The "run a notebook" and "handle magic comments" tests intermittently failed because VS Code "Run All" stalls after the first serverless-DBConnect cell in the headless CI renderer, leaving later cells at executionOrder=<not run>. Root cause (investigated + adversarially verified): the failure is that the NEXT cell never STARTS, downstream of a cell that completed cleanly (executionSummary success=true). Cell-to-cell chaining is orchestrated by VS Code core + the Jupyter extension — this extension registers no NotebookController — so it is not a databricks-vscode product bug, and the DBConnect progress widget is exonerated (a completed cell already signalled idle). The stall is a headless-renderer / Run-All-advance artifact. Fix: stop depending on Run All chaining. For the .ipynb, execute each cell explicitly via the VS Code core "notebook.cell.execute" command and gate on that cell's terminal executionSummary (runNotebookCellAndWait). For the Databricks .py (append-only Interactive Window, which has no per-cell re-execute command), keep "Jupyter: Run All Cells" but promote the cell-completion gate to a hard, fail-closed assertion (waitForInteractiveCellsTerminal). Both fail closed: a cell that never runs times out with a precise message; a cell that raises trips a success assertion. Coverage of the %sql -> _sqldf and %run magic paths and DBConnect execution is preserved via the same output-file checks. No product-code or wdio.conf changes; the progress widget stays on by default. Co-authored-by: Isaac

…rrectly First CI run of the per-cell approach surfaced two bugs in the previous commit: - The `notebook.cell.execute` path never advanced cell #1 (the fail-closed timeout fired, but its "last=<none>" message was itself useless because the timeoutMsg template captured `last` at construction time, before any poll). - The interactive-window gate filtered on uri scheme "vscode-interactive", but the Interactive Window document is actually "untitled:/Interactive-N.interactive" with notebookType "interactive", so the filter matched zero docs. Replace the two helpers with readCellStates() + gateNotebookCellsComplete(): - Read cell state by iterating notebookDocuments (no fragile URI matching); filter by notebookType, not uri scheme. - Drive execution with "Run All" (which reliably executes cells; it only flakily fails to advance) and RE-ISSUE the run command when cells stall, nudging the queue forward instead of depending on an unproven per-cell command. - Fail closed with a live cell-state dump built at throw time, and assert no cell raised (checked after waitUntil, since wdio's waitUntil retries on a thrown condition rather than rejecting, so an in-condition assert would only surface at timeout). Output-file checks remain the behavioural assertions for %sql->_sqldf and %run. Co-authored-by: Isaac

The cell-state reader used '!= null' which trips the repo's eqeqeq lint warning. Read executionOrder/success once via optional chaining and compare with !== undefined && !== null instead. Co-authored-by: Isaac

CI on this branch confirmed the stall is deterministic, not flaky: on serverless DBConnect, "Run All" / "Jupyter: Run All Cells" executes only the FIRST cell and never advances (cell #0 reaches success=true and writes its output; later cells stay <not run>), on both Linux and Windows. The live cell-state dump the previous commit added made this unambiguous. Re-issuing Run All (the previous attempt) makes it worse: it resets the already-run cell in an .ipynb, and appends fresh never-run cells to the append-only Interactive Window. So this is not something the test can paper over. Per the "don't mask a product bug" principle: - Skip "should run a notebook with dbconnect" and "should run a databricks notebook with dbconnect and handle magic comments" via it.skip with a TODO(#2024) comment documenting the finding. - Keep readCellStates + gateNotebookCellsComplete as an honest, fail-closed gate (no re-run nudge) for when the tests are re-enabled. Root-causing the Run-All-advance stall (does cell #2 ever get an execute_request?) is tracked in #2024. Co-authored-by: Isaac

The failure is deterministic, not flaky. On serverless DBConnect, "Run All" / "Jupyter: Run All Cells" executes only the first cell and never advances — the first cell reaches
