Hybrid MTP Adapter

Prova implements a Hybrid Adapter for the Microsoft Testing Platform (MTP). This allows Prova to provide its own high-performance AOT engine while still participating in the broader .NET testing ecosystem.

How it Works

Unlike traditional adapters that are discovered via reflection at runtime, Prova's MTP adapter is Source Generated.

1. Source Generation: Prova generates an MTP ITestApplication entry point.
2. Registration: Your tests are registered as MTP-compatible tests.
3. Execution: When you run dotnet test, MTP initializes Prova's engine.

Why Hybrid?

• AOT Performance: Standard MTP adapters often rely on reflection or dynamic loading, which are slow or incompatible with Native AOT.
• Ecosystem Support: By supporting MTP, Prova can output TRX files, integrate with Visual Studio's Test Explorer (experimental), and work with CI reporters.

Usage

To enable MTP support, ensure you have the Microsoft.Testing.Platform.MSBuild package in your project.

<PackageReference Include="Microsoft.Testing.Platform.MSBuild" Version="1.0.0" />

Running with MTP Features

You can use standard MTP arguments:

# Generate a TRX report
dotnet test -- --report-trx

# Filter tests using MTP syntax
dotnet test -- --filter "Namespace=CalculatorTests"

Future Road Map

We are working on deeper integration to support:

• Hot Reload
• Improved VS Test Explorer integration
• Custom MTP extensions for Prova-specific features (like allocation tracking)
