## Summary of the Pull Request
This pull request introduces enhancements to UI test automation,
improvements to pipeline configuration, and project structure updates.
The goal is to improve flexibility, maintainability, and efficiency in
PowerToys’ CI/CD processes.

### UI Test Enhancements:
Delayed Text Input Support
- UI tests now support character-by-character text input with
configurable delays.
- This serves as a workaround for a known CmdPal bug where input is
swallowed too quickly. The delay mitigates the issue until it is fixed
in CmdPal.
 
Centralized Environment Management
- Introduced a new class to centralize environment variable access for
UI test configuration.

CmdPal Launch Handling in Pipelines

- Adjusted test logic to handle CmdPal module startup specifically in CI
pipelines



### Pipeline Configuration Updates:
Build Artifact Customization

- Included test-related folders in pipeline build outputs for better
traceability.

Support for Build ID Targeting

- Added support for specifying PowerToys build IDs in test pipelines,
with conditional logic for specific or latest build selection.

https://github.com/microsoft/PowerToys/pull/40754

 ### Pipeline Options
 
-- **useLatestOfficialBuild**: When checked, downloads the latest official PowerToys build and installs it for testing. This skips the full solution build and only builds UI test projects.
+- **buildSource**: Select the build type for testing:
+  - `latestMainOfficialBuild`: Downloads and uses the latest official PowerToys build from main branch
+  - `buildNow`: Builds PowerToys from current source code and uses it for testing
+  - `specificBuildId`: Downloads a specific PowerToys build using the build ID specified in `specificBuildId` parameter
 
-- **useCurrentBranchBuild**: When checked along with `useLatestOfficialBuild`, downloads the official build from the current branch instead of main.
+  **Default value**: `latestMainOfficialBuild`
 
-  **Default value**: `false` (downloads from main branch)
+- **specificBuildId**: When `buildSource` is set to `specificBuildId`, specify the exact PowerToys build ID to download and test against.
+
+  **Default value**: `"xxxx"` (placeholder, enter actual build ID when using specificBuildId option)
   
   **When to use this**:
-  - **Default scenario**: The pipeline tests against the latest signed PowerToys build from the `main` branch, regardless of which branch your test code changes are from
-  - **Custom branch testing**: Only specify `true` when:
-    - Your branch has produced its own signed PowerToys build via the official build pipeline
-    - You want to test against that specific branch's PowerToys build instead of main
-    - You are testing PowerToys functionality changes that are only available in your branch's build
+  - Testing against a specific known build for reproducibility
+  - Regression testing against a particular build version
+  - Validating fixes in a specific build before release
   
-  **Important notes**:
-  - The test pipeline itself runs from your specified branch, but by default tests against the main branch's PowerToys build
-  - Not all branches have signed builds available - only use this if you're certain your branch has a signed build
-  - If enabled but no build exists for your branch, the pipeline may fail or fall back to main
+  **Usage**: Enter the build ID number (e.g., `12345`) to download that specific build. Only used when `buildSource` is set to `specificBuildId`.
 
 - **uiTestModules**: Specify which UI test modules to build and run. This parameter controls both the `.csproj` projects to build and the `.dll` test assemblies to execute. Examples:
   - `['UITests-FancyZones']` - Only FancyZones UI tests

 ### Building PowerToys Locally
 
+#### One stop script for building installer
+1. Open developer powershell for vs 2022
+2. Run tools\build\build-installer.ps1
+> For the first-time setup, please run the installer as an administrator. This ensures that the Wix tool can move wix.target to the desired location and trust the certificate used to sign the MSIX packages.
+
+The following manual steps will not install the MSIX apps (such as Command Palette) on your local installer.
+
 #### Prerequisites for building the MSI installer
 
 1. Install the [WiX Toolset Visual Studio 2022 Extension](https://marketplace.visualstudio.com/items?itemName=WixToolset.WixToolsetVisualStudio2022Extension).

+## If for any reason, you'd like to test winget install scenario, you can follow this doc:
+
+### Powertoys winget manifest definition:
+[winget repository](https://github.com/microsoft/winget-pkgs/tree/master/manifests/m/Microsoft/PowerToys)
+
+### How to test a winget installation locally:
+1. Get artifacts from release CI pipeline  Pipelines - Runs for PowerToys Signed YAML Release Build, or you can build one yourself by execute the 
+ 'tools\build\build-installer.ps1' script
+
+2. Get the artifact hash, this is required to define winget manifest
+```powershell
+cd /path/to/your/directory/contains/installer
+Get-FileHash -Path ".\<Installer-name>.exe" -Algorithm SHA256
+```
+ 3.  Host your installer.exe - Attention: staged github release artifacts or artifacts in release pipeline is not OK in this step
+You can self-host it or you can upload to a publicly available endpoint  
+**How to selfhost it** (A extremely simple way):
+```powershell
+python -m http.server 8000
+```
+
+4. Download a version folder from wingetpkgs like: [version 0.92.1](https://github.com/microsoft/winget-pkgs/tree/master/manifests/m/Microsoft/PowerToys/0.92.1)
+and you get **a folder contains 3 yml files**
+>note: Do not put any files other than these three in this folder
+
+5. Modify the yml files based on your version and the self hosted artifact link, and modify the sha256 hash for the installer you'd like to use
+
+6. Start winget install:
+```powershell
+#execute as admin
+winget settings --enable LocalManifestFiles
+winget install --manifest "<folder_path_of_manifest_files>" --architecture x64 --scope user
+```
