Performance

Prova is designed for speed. Leveraging its AOT (Ahead-of-Time) compilation and parallel execution capabilities can significantly reduce your test suite's runtime.

AOT Optimization

Unlike traditional test runners that rely on reflection at runtime, Prova generates execution code at compile-time.

• Instant Startup: Tests start executing immediately without a "discovery" phase or JIT overhead.
• Small Footprint: Prova results in smaller binaries, which is ideal for CI/CD environments and containerized builds.
• Native AOT: Prova is fully compatible with .NET's Native AOT publishing, allowing you to run your tests as standalone native binaries.

Parallel Execution

Maximize your hardware by running tests in parallel.

Enabling Parallelism

You can enable parallel execution at the assembly, class, or method level using the [Parallel] attribute.

[assembly: Parallel(concurrency: 4)] // 4 tests at once

Resource Constraints

Use [NotInParallel] or [ParallelGroup] to protect tests that share global state (like a database or file system).

[NotInParallel] // Won't run with other tests marked the same
public void DatabaseTest() { ... }

Lightweight Data

Data generation can become a bottleneck.

• Prefer InlineData: Use [InlineData] for simple parameter sets. It's the most efficient way to parameterize tests.
• Lazy MemberData: If using [MemberData], ensure the data generation itself is efficient and doesn't perform heavy computations or I/O unless necessary.

Filtering

Run only what you need. Prova's CLI allows for fast, hierarchical filtering so you don't waste time running irrelevant tests.

# Run only security-related tests
./MyTestProject --filter "Security.*"
