## Summary Adds end‑to‑end UI tests on the `Microsoft.PowerToys.UITest.Next` (winappcli) framework for three modules, grows the shared `.Next` test framework with the helpers those suites needed, and adds the CI plumbing that lets shell‑extension tests exercise the **real** Windows 11 modern context menu. Also ships two agent skills that document how to write and run these tests. Product runtime behavior is **unchanged** — the only product edits are test‑observability hooks in Peek and a unit‑test project exclude. Closes: https://github.com/microsoft/PowerToys/issues/40660 https://github.com/microsoft/PowerToys/issues/49424 https://github.com/microsoft/PowerToys/issues/40661 ## What's added ### New UI test suites - **Image Resizer** — `src/modules/imageresizer/tests/ImageResizer.UITests`: context‑menu enable/disable tracking, the resize dialog, custom presets, every fit mode, every unit, filename format, keep‑date, shrink‑only, replace‑in‑place, and orientation. - **Peek** — `src/modules/peek/Peek.UITests.Next`: file‑preview coverage across image/text/archive/ markdown types with per‑arch visual baselines. - **File Explorer add‑ons** — `src/modules/previewpane/PreviewPane.UITests`: Preview Pane handlers and thumbnail providers. ### `UITestAutomation.Next` framework - New helpers: `ExplorerShell` (Shell selection/view‑mode interop), `WaitHelper` (structured stable waits), `WindowControl` (foreground/context‑menu/process control), `VisualAssert` (image compare), `WindowHelper`. - Updates to `Session`, `UITestBase`, `SettingsConfigHelper`, `WinappCli`. - New `UITestAutomation.Next.UnitTests` project covering the new wait/settings/CLI helpers. ### CI — sign sparse MSIX so the modern menu registers - **`.pipelines/signSparsePackages.ps1`** — self‑signs each sparse context‑menu MSIX with a publisher‑matching test certificate and force‑trusts it (machine stores), so `AddPackageByUriAsync` succeeds on otherwise‑unsigned PR builds. Robust `signtool` discovery with a NuGet fallback; test‑only trust that asserts no security. - Wired into **`.pipelines/v2/templates/job-test-project.yml`** as a best‑effort step covering the run‑in‑place, machine‑install, and per‑user‑install locations. Signs nothing it can't (skips already‑signed packages) and never fails the job. ### Product changes (test observability only) - **Peek `FilePreview.xaml` / `.xaml.cs`** — a named `LoadingIndicator` and a hidden automation peer that exposes the current preview state as text, so tests can read load state deterministically. No runtime behavior change. - **`ImageResizer.UnitTests.csproj`** — exclude the sibling `ImageResizer.UITests\**` folder from the unit‑test compilation. ### Agent skills & docs - **New `ui-tests-local-vm` skill** — run `.Next` suites in persistent dockur/windows VMs: setup, agentic loop, image customization, troubleshooting, the shell‑extension **signing** reference, plus controller/guest scripts and VM templates. - **Updated `ui-tests-migration` skill** — WinAppDriver/Selenium → `.Next` porting guidance (CI stability, Explorer/shell‑extension test design, patterns & pitfalls). - **`doc/devdocs/development/ui-tests.md`** — updated for the `.Next` workflow. ## Testing - All three suites pass locally and in CI across **x64 Win10**, **x64 Win11**, and **arm64** (machine and per‑user install legs). ## Reviewer notes - No product runtime behavior changes; product edits are limited to the Peek test hooks above. - The CI signing step is a **test‑only** trust anchor (self‑signed, scoped to the agent) and is best‑effort, so it can only add modern‑menu coverage and never regress the job.
