Roadmap: v0.4.0 (Developer Experience)

We are committed to bringing "Dev-First" features to Prova while maintaining our "Ops-First" stability.

🛠️ Automated Migration (Code Fixers)

Goal: Reduce migration friction to near-zero.

• [x] xUnit Analyzer: Detect using Xunit; and suggest using Prova;.
• [x] NUnit Analyzer: Detect [TestFixture], [Test] and suggest Prova equivalents. [NEW]
• [x] MSTest Analyzer: Detect [TestClass], [TestMethod] and suggest Prova equivalents. [NEW]
• [x] Fixer: Automatically convert incompatibilities (ICollectionFixture, TestContext access).

📊 Integrated Code Coverage

Goal: Native coverage without external tool complexity.

• [x] LCOV Support: Emit coverage reports during source generation.
• [x] Native Collector: Hook into the static entry point.

🪝 Lifecycle & Control

Goal: Granular control over test execution and data.

• [x] Hooks: [Before], [After], [BeforeClass], [AfterClass], [BeforeAssembly], [AfterAssembly], [BeforeAll], [BeforeEach], [AfterAll], [AfterEach]. [NEW]
• [x] Global Hooks: [BeforeEvery(Test)], [BeforeEvery(Class)] for cross-cutting concerns. [NEW]
• [x] Parallelism: [NotInParallel] attribute with Constraint Keys (e.g. "Database"). [NEW]
• [x] Parallel Groups: [ParallelGroup("key")] to run specific groups in parallel while isolating others. [NEW]
• [x] Parallel Limiter: [ParallelLimiter<T>] to restrict concurrency for specific resources. [NEW]
• [x] Flow Control: [Retry(3)], [Repeat(3)], and [Timeout(3000)]. [NEW]
• [x] Culture: [Culture("en-US")] to run tests under specific culture settings. [NEW]
• [x] Global Policies: Assembly-level defaults for Retry, Timeout, and Parallelism. [NEW]
• [x] Data Sources: [ClassDataSource], [MethodDataSource] for flexible DI. [NEW]
• [x] Generic Tests: [Test] on generic classes/methods with type arguments. [NEW]
• [x] Properties: [Property("key", "val")] for test filtering and metadata. [NEW]
• [x] Filters: CLI dotnet run --treenode-filter support. [NEW]
• [x] Events: ITestStartEventReceiver, ITestEndEventReceiver for lifecycle observation. [NEW]
• [x] Custom Executors: ITestExecutor and IHookExecutor (AOT Safe). [NEW]
• [x] Scripting: Support for file-based test execution (dotnet run tests.cs). [NEW]
• [x] TestContext: Refactor to expose Events, Metadata, and Result properties clearly. [NEW]
• [x] State Sharing: StateBag to pass data from Discovery -> Execution phase. [NEW]

🔌 Extensibility & Advanced Scenarios

Goal: Allow users to customize every aspect of the engine.

• [x] Test Variants: Dynamic test generation (e.g. valid vs invalid inputs) via [TestVariant]. [NEW]
• [x] Dynamic Tests: Imperative test generation via DynamicTestBuilder (code-based). [NEW]
• [x] Detailed Configuration: testconfig.json support for environment-specific settings. [NEW]
• [x] Combinatorial Tests: [Matrix] attribute for testing all combinations of input data. [NEW]
• [x] Data Generators: [DataSourceGenerator] base class for custom data sources. [NEW]
• [x] Formatters: [ArgumentDisplayFormatter] to control argument presentation in logs/UI. [NEW]
• [x] Display Names: [DisplayName("...")] with placeholders for arguments ({0}). [NEW]
• [x] Logging: ITestLogger infrastructure and TestContext.Logger sinks. [NEW]
• [x] Debugging Support: Crash Dumps and Hang Dumps integration (via MTP extensions). [NEW]

💉 Dependency Injection

Goal: First-class DI support.

• [x] Constructor Injection: Support injecting services into Test Classes. [NEW]
• [x] Class Factories: IClassConstructor helper for complex instantiation logic. [NEW]
• [x] DI Data Sources: [DependencyInjectionDataSource] to source data from containers. [NEW]
• [x] ASP.NET Core: WebApplicationFactory integration for integration testing. [NEW]

📸 Artifacts & Observability

Goal: First-class support for test outputs.

• [x] Attachments: TestContext.Output.AttachArtifact(...) for files/screenshots. [NEW]
• [x] Session Artifacts: Logs/Reports that span the entire test run. [NEW]
• [x] CI/CD Integration: Native support for GitHub Actions and Azure DevOps reporting. [NEW]

🧩 Integrations & Ecosystem

Goal: Seamless integration with the .NET ecosystem.

• [x] Playwright: First-class support for UI testing with PageTest base class. [NEW]
• [x] FsCheck: Property-based testing integration ([Property]). [NEW]
• [x] Testcontainers: Orchestration for complex dependencies (Docker, Postgres). [NEW]
• [ ] Aspire: Integration with .NET Aspire for microservices testing. [NEW]

📚 Documentation & Guides

Goal: comprehensive learning resources.

• [ ] Best Practices: Guide on Naming, Organization, and Assertions. [NEW]
• [ ] Performance: Guide on [ACT] mode, lightweight data, and parallel optimization. [NEW]
• [ ] Orchestration: Guide on managing complex test infrastructure. [NEW]
