vanilla-test

C# · native + browser WebAssembly

Keep the suite C#.

Use the dependency-free .NET 8 core natively, then publish the existing parameterless MSTest inventory as a .NET 10 browser WebAssembly AppBundle. One C# test assembly supplies both lanes.

Run the browser suite Open the C# API View package assets
Native

.NET owns the core path.

gh release download 2.1.3 --repo RIAEvangelist/vanilla-test --pattern '*.nupkg' --dir ./packages
dotnet add package vanilla-test --version 2.1.0 --source ./packages
dotnet test

VanillaTestSuite is a small net8.0 state machine with PascalCase lifecycle methods, typed errors, and an immutable cached result. The package has no third-party runtime dependency.

Browser

One command emits the AppBundle.

dotnet workload install wasm-tools
dotnet tool install --global vanilla-test.tool --version 2.1.0 --add-source ./packages
dotnet vanilla-test --browser

The .NET 10 tool generates a multi-file browser-wasm host beside the selected MSTest project. The page imports the runtime, runs the existing parameterless methods once, and exposes both on-page checks and captured console output.

Contract

A small native state machine.

One active case, exact unique descriptions, first decision wins, undecided completion fails, and reporting seals the suite. C# uses standard exceptions and read-only collections instead of copying another runtime's surface.

Coverage

Native source coverage

Review the enforced 100% line and branch evidence for the core assembly without conflating it with browser compatibility.

Packages

Library and tool

vanilla-test 2.1.0 is the .NET 8 core. vanilla-test.tool 2.1.0 is the .NET 10 browser builder. Both are currently GitHub release assets, not NuGet.org packages.

Native and browser gates

CI runs the seven core MSTest methods—including Behavioral coverage—natively, verifies package and tool behavior, then executes that core inventory inside the published AppBundle.

The host boundary is explicit.

Stable MSTest 4.3.3 does not provide the Microsoft.Testing.Platform browser path this lane requires. The tool does not run MTP. It generates a compact reflection host for public, parameterless [TestMethod] methods and leaves full adapter services on the native path.

One C# harness runs the aligned one-million-case, 1,000-suite workload in native .NET and browser WebAssembly. Inspect every sample and the exact source/runtime provenance. Run it in this browser.
