Running

dotnet test --project Checkout.Tests/Checkout.Tests.csproj

Or run the test binary directly for the platform's own CLI:

dotnet run --project Checkout.Tests -- --list-tests

global.json opts dotnet test into the Microsoft.Testing.Platform runner, which the .NET 10 SDK requires for MTP-based projects. The SDK reads it from the directory the command is run in, upward — so it goes at the repository root, not beside the project; see Installing.

On a build agent, Running a suite on CI is a complete Azure Pipelines example — environment, filters, parallelism, retries and each reporter chosen from the Run pipeline dialog — with the two YAML files to copy into a suite's repository.
