test(e2e): set vault options in memory so a restore holds under load by chhoumann · Pull Request #2216 · chhoumann/quickadd

chhoumann · 2026-10-09T07:09:02Z

Why

In a full native run on a busy machine, empty-format-default, external-settings-change and global-var-autocomplete failed: the Settings button they click was not in the main window. settings-popout-save turns on Obsidian's settingsPopoutWindow with app.vault.setConfig and restores it afterwards. setConfig also writes app.json a second later, and Obsidian reloads app.json when it changes on disk. Under load it reloaded its own late write after the restore, so every later spec opened Settings in a popout.

What changed

setVaultConfig in tests/e2e/uiHelpers.ts sets a vault option in memory, without writing app.json. Every native spec that changed a vault option now uses it, and daily-note-token drops its saveConfig workaround for the same race.
tests/e2e-vault-config.test.ts fails when a spec under tests/e2e calls setConfig, saveConfig or requestSaveConfig.

Scope

Test code only, no release. It leaves out settings-popout-save's own disk check, which still fails under load (#2213), and the menu specs that always fail on macOS because Obsidian uses native menus there.

Verification

Repro before the fix: a full native run at load ~100 failed exactly the five tests from the issue. A loop of settings-popout-save then the three specs under load ended with settingsPopoutWindow: true and the same errors. Alone, setConfig(true) then setConfig(false) ended true in 3 of 8 tries under load, 0 when idle.
After the fix: two full native runs at load 11 to 180 passed all 9 tests of the three specs, including one where settings-popout-save failed first. The other failures in those runs are in specs this change does not touch. Most fail the same way on master on this Mac.
pnpm run build, pnpm run lint and pnpm run test pass. The new guard fails when one setConfig or saveConfig () call is put back.

Fixes #2207

Note

Set vault options in memory in E2E tests so restore holds under load

Adds setVaultConfig in uiHelpers.ts that writes vault options directly on the in-memory vault configuration, avoiding Obsidian's persisting configuration setter
Migrates all E2E specs that used direct vault configuration mutation or save calls (conditional-branch-persistence, daily-note-token, drag-pill-bounds, package-import-*, prompt-cancellation, script-picker-paths, script-syntax-error, settings-popout-save, template-cursor) to the new helper for setup and cleanup
Adds a policy test in e2e-vault-config.test.ts that scans E2E TypeScript files and fails on any direct vault configuration mutation or save call
Risk: setVaultConfig does not persist to disk, so tests that relied on configuration surviving across reloads must use in-memory values only

Summary by CodeRabbit

Tests
- Updated end-to-end test setup to handle vault preferences consistently across scenarios, including restoring prior settings after tests run.
- Added checks to flag test configurations that bypass the supported preference-setting approach.
- Existing test scenarios and application behavior are unchanged; this update does not add user-facing features.

setConfig and saveConfig write .obsidian/app.json. Under load Obsidian reads its own late write back after a spec restores the option, so the option stays changed for every later spec (#2207). This check fails while any spec under tests/e2e still calls them. Refs #2207

settings-popout-save turned on settingsPopoutWindow with setConfig and restored it afterwards. setConfig also writes app.json a second later, and under load Obsidian picked that write up after the restore and turned the option back on. Every later spec then opened Settings in a popout and found no choice list in the main window, which failed empty-format-default, external-settings-change and global-var-autocomplete in full runs. setVaultConfig sets the option on app.vault.config without writing app.json. All native specs now use it, and daily-note-token no longer needs its saveConfig workaround. Fixes #2207

Walkthrough

E2E tests use setVaultConfig to change vault settings in memory instead of writing them through the vault configuration API. A Vitest check scans E2E TypeScript files for specified configuration-writing calls.

These E2E tests use it to set and restore configuration values.
Configuration-write guard `tests/e2e-vault-config.test.ts`	A Vitest check recursively scans E2E TypeScript files for `setConfig`, `saveConfig`, or `requestSaveConfig` calls and fails with guidance if it finds any.

Change: Bug fix · Severity of issue fixed: Medium

Merge Risk: 🔵 Low · up to 52afa

This change only affects E2E tests. The new guard can miss a prohibited vault-config write when the call is formatted across lines. Merging is low risk, and the guard can be tightened in a follow-up.

Independent verification: PASS+NOTES

Verified head 52afaf8 against base eaa72c8, patch-id e4c271110991cbae8097fa4ba77a6a7121f14506 (matches). Native Obsidian 1.14.3, isolated worktree vault, 6 to 12 extra CPU spinners on a 16-core Mac.

Guard: tests/e2e-vault-config.test.ts passes at head. With master's tests/e2e it fails and lists 23 setConfig call sites across 12 spec files.
Base mechanism: setConfig(true), wait for disk true, then setConfig(false). 2 of 8 runs ended true in memory and on disk at load 14.6 to 15.2 (run 5 never saw the true write within 10 s, so 2 of 7 valid flips). Obsidian read its own late write back after the restore, as the PR describes.
Head mechanism: toggling app.vault.config.settingsPopoutWindow left app.json mtime and size unchanged in 3 of 3 runs. Settings opened in a popout while true and in the main window after false.
Six-spec set at head, 3 runs at load 15 to 30: 57/58, 57/58, 58/58. app.json mtime never changed. empty-format-default, external-settings-change, global-var-autocomplete and settings-popout-save (both window states) passed in all 3 runs. The same set with master's specs passed 58/58 once and rewrote app.json.
Note: the two head failures were load flakes, not regressions. daily-note-token "captures into the note Daily notes opens" failed once and then passed 2/2 at head and 2/2 at base in isolation. template-cursor "restores Live Preview typing ... rename=false" failed once and then passed in 3 isolated head runs. Isolated template-cursor runs had 1 failure in 3 at head and 4 failures in 3 at base, all in tests this PR does not touch.
