From d5d237ed71e4ea1977a62d030833729d88b0312e Mon Sep 17 00:00:00 2001 From: Anton Nekipelov <226657+anton-107@users.noreply.github.com> Date: Thu, 16 Jul 2026 12:59:26 +0200 Subject: [PATCH] test(e2e): de-flake run_dbconnect setup and notebook run-all Windows venv creation + dependency install is far slower than Linux, and the 'environment is selected' / 'Databricks Connect' prompt toasts frequently expired the fixed 60s notification waits before firing, failing 'should setup virtual environment' and cascading to the three run tests. Gate the setup on the filesystem ground truth (the .venv interpreter existing, 240s budget) instead of a transient toast, make the Databricks Connect prompt tolerant, and fall back to the 'Reinstall Databricks Connect' command when the toast never shows. Because the venv-exists poll now precedes ensureVenvHasKernelDeps, the kernel deps reliably land in the interpreter the kernel launches (fixing the Windows 'requires the notebook package' kernel failure). For the notebook run tests, add a selector-independent cell-completion gate: after Run All, wait for every code cell to leave ''. This converts a silent 120s/180s output-file timeout (seen on Linux when Run All stops after the first cell) into a precise '/ cells never ran' signal so a real run-all chaining stall surfaces instead of masquerading as a missing file. Also thread an optional timeout into waitForNotification.
