[Feature]: Enhanced Health Metrics

[Grant-Archibald-MS]

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

With the health coverage metric of the avaliable tests
