Context

Adds E2E coverage for two contour utilities on the hydrated RTSTRUCT study, extending the contour test suite (#6117, #6206).

Changes & Results

Merge operation (ContourCombineOperations.spec.ts)

  • New test: merge Big Sphere with nested Small Sphere (no edge crossing) produces a single new segment shaped like Big Sphere.
  • Since the union looks identical to Big Sphere, the test asserts exactly one contour path for the result on top of the panel row assertions — guarding against a silent no-op (empty segment) or a holed result — and pairs that with a viewport screenshot.

Smooth Edges operation (ContourSmoothOperation.spec.ts, new)

  • Covers Smooth Edges (the smoothContours command) from the "Smooth Contours" utility popover, acting on the active Threshold segment.
  • Captures the segment's SVG path as a baseline, smooths, then uses web-first retrying assertions: the path count stays 1, the d attribute no longer matches the baseline, and the contour stays closed (/Z\s*$/), followed by a viewport screenshot of the smoothed result.
  • Page object: adds a smoothContours popover object (open/close/smoothEdges) to RightPanelPageObject; close dismisses the popover so it does not overlap the screenshot.

Testing

pnpm run test:e2e tests/ContourCombineOperations.spec.ts
pnpm run test:e2e tests/ContourSmoothOperation.spec.ts

📝 Walkthrough

Walkthrough

The test suite adds end-to-end coverage for contour merge and smoothing workflows. It validates merge output segments and viewport paths, and verifies that smoothing changes contour geometry while preserving a single contour path.

Changes

Contour operations

Layer / File(s) Summary
Contour operation controls
tests/pages/RightPanelPageObject.ts
The page object opens operation popovers before merge or smoothing actions. It adds guarded open behavior and merge popover closing.
Merge operation coverage
tests/ContourCombineOperations.spec.ts
Adds a merge test for Big Sphere and Small Sphere. The test validates the new segment, one contour path, and the active viewport screenshot.
Smooth contour workflow
tests/ContourSmoothOperation.spec.ts, tests/utils/screenShotPaths.ts
Adds smoothing setup and assertions for changed contour geometry and one contour path. It adds screenshot mappings for the merge and smoothing results.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 3b41e

This change adds end-to-end coverage for contour merge and smoothing workflows. The smoothing scenario verifies a single resulting contour path and changed geometry, with no remaining merge-blocking risk identified.

So at least some tools (see the MainToolbarPageObject) we actually combine opening the menu/popup and clicking the suboption/submenu. Here we could check if the popup is open first and if not open it. Also, please don't kill me 🤣, let's double check various other page objects for consistency in this regard.

Done. It also checks if opened first.

await combineContours.apply();
await viewportRenderCycle;

await expect(contourSegmentationPanel.panel.rows).toHaveCount(5);

Should we check the original number of segments before the operation?
