Follow-up to #12243 (issue #12239).

The NewMachineSheetKindUITests XCUITest merged with #12243 opens the sheet correctly (the hosted lane's recording shows Kind: Desktop | Base with Desktop preselected), but it failed on the hosted lane for two locator reasons: a whole-app static-text predicate walked the terminal's accessibility tree and timed out, and once scoped, the summary Text under the picker is not exposed with a queryable label at all. The segments, by contrast, are radio buttons whose accessibility value is 1 when selected (desktop=Optional(1) base=Optional(0) in the run logs).

This change scopes every query to the sheet and asserts the selection through the segment values: Desktop on and Base off when the sheet opens, the reverse after clicking Base, then Cancel closes the sheet. The summary text is logged for the record, not asserted.

Tests: hosted test-e2e.yml run of cmuxUITests/NewMachineSheetKindUITests with record_video=true, linked in a comment when green. python3 scripts/swift_file_length_budget.py passes.

Note

Low Risk
Test-only changes to XCUITest locators and assertions; no production or runtime behavior is modified.

Overview
New Machine kind picker UI test is updated so hosted CI stops timing out and still verifies Desktop/Base behavior.

All element lookups run against app.sheets.firstMatch (picker segments, cancel, summary) instead of the full app, avoiding walks through the terminal’s large accessibility tree.

Assertions now use the Desktop/Base radio segments’ accessibility values via segmentIsOn (Desktop on / Base off at open; reversed after clicking Base). Whole-app static-text predicates on the kind summary are removed; summary is only logged through NewMachineSheet.kindSummary when exposed.

Summary by CodeRabbit

  • Tests
    • Improved automated coverage for the New Machine workflow.
    • Updated machine-type selection and cancellation checks to use more reliable sheet-scoped interactions.
    • Added accessibility-value validation for machine-type segments, reducing failures caused by timeouts and complex terminal interface elements.

Summary by cubic

Makes the New Machine sheet kind picker tests reliable in CI. The previous whole-app text predicates timed out on the terminal's accessibility tree, and the summary text under the picker wasn't queryable.

Written for commit 61ec697. Summary will update on new commits.

Review in cubic

…lues

Follow-up to #12243 for #12239. The hosted lane records the sheet with
Desktop preselected, but the test's static-text predicate for the summary
never matched (SwiftUI does not expose that text with a queryable label),
and unscoped queries walk the terminal's accessibility tree and time out.
Scope every query to the sheet and assert the selection through the
segments' accessibility values (1 = on), which the runs proved readable
(`desktop=Optional(1) base=Optional(0)`); the summary is logged only.

📝 Walkthrough

Walkthrough

The New Machine sheet UI test scopes control queries to the sheet and validates segment accessibility values instead of summary text or selection state.

Changes

New Machine Sheet UI Tests

Layer / File(s) Summary
Sheet scoping and segment assertions
cmuxUITests/NewMachineSheetKindUITests.swift
Desktop, Base, and Cancel queries use the sheet scope. Segment checks use segmentIsOn and accessibility values. Debug output reports the summary label and value.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 61ec6

The UI test now targets the New Machine sheet directly and verifies picker state through accessible segment values, reducing unrelated-element matches without changing product behavior. No current merge-blocking risk remains.

sheet.waitForExistence(timeout:) causes the test to fail rather than falling
back to app. Keep sheet as the sole query root for the radio buttons and Cancel
control, ensuring the test only passes when the New Machine sheet is present.

A picker found outside the sheet would not be this sheet; assert the sheet
exists on the main window and scope every query to it.

Hosted test-e2e.yml run of cmuxUITests/NewMachineSheetKindUITests on this branch (before the strict-sheet tweak): success, https://github.com/manaflow-ai/cmux/actions/runs/34437243508 (video in the test-recording artifact; log line segments: desktop=Optional(1) base=Optional(0) summary=<not exposed>). The re-run with the strict sheet assertion is https://github.com/manaflow-ai/cmux/actions/runs/34438448146.

Heads-up from #12250 (issue #12244): Austin asked for one New Machine flow and one snapshot ladder, so that PR removes the Desktop | Base picker that #12243 added to the sheet and to Set Up Base, and rewrites NewMachineSheetKindUITests to assert that no switcher exists (Create and Cancel matched by identifier or label, hierarchy printed when the sheet does not open, a recording attached). The segment-value assertions here would no longer have a picker to read once #12250 merges, so this PR would need to be closed or rebased onto that test. For the record, on the hosted lane the sheet does open via the palette signed out (the run's recording shows it); what fails in main's version of the test is the summary text lookup, not the sheet.
