[Feature]: Enhanced Health Metrics

Start by reviewing issue #594 and the current PowerAppsTestEngine health-check report flow shown in the PowerShell example. Define how solution selection, component discovery, coverage scope, and the HTML summary should work for the listed Power Platform resources. Done means the feature has agreed behavior for identifying covered and uncovered components and generating the requested coverage report.

Is your feature request related to a problem? Please describe.

While the current implementation Model Drivel Application - Health Check Test Coverage Report #594 provides a pass/fail metric for test execution, it does not offer insight into the coverage of tests across the testable resources within a Power Platform solution. This limits the ability to assess how comprehensively the solution is being validated through automated tests.

Describe the solution you'd like

Introduce a feature that enables users to:

• Specify a solution (e.g., by name or ID)
• Automatically discover testable components within that solution
• Generate a coverage report indicating which components are covered by tests and which are not
• Define scope to indicate what components that the tests health check metric should cover

Testable Components to Include

• Canvas Apps
    - Pages (Screens)
• Model-Driven Apps
    - Entity List Pages
    - Entity Detail Pages
    - Custom Pages
• Web Resources
    - JavaScript files used in Model-Driven Apps
• Dataverse
    - Plugins
    - Entities
• AI Builder
    - Trained AI Models

Current process example using features from Model Drivel Application - Health Check Test Coverage Report #594 a

$env:user1Email = "test@contoso.onmicrosoft.com"
dotnet PowerAppsTestEngine -i test.te.yaml -p mda -e $envId -t $tenantId -d $testPage --run-name "Sample"
dotnet PowerAppsTestEngine -i test2.te.yaml -p mda -e $envId -t $tenantId -d $testPage --run-name "Sample"

$folderPath = "$env:USERPROFILE\AppData\Local\Temp\Microsoft\TestEngine\TestOutput"
$reportPath = [System.IO.Path]::Combine($folderPath, "test_summary_$runName.html")

dotnet PowerAppsTestEngine  --run-name "Sample" --output-file $reportPath

Could generate a summary report like
