Precept.TestPlatform

Precept's test runner: a Microsoft.Testing.Platform test framework that discovers and executes Precept tests. A test project starts here — this package brings in Precept.Core, makes the project an executable and generates its entry point.

dotnet add package Precept.TestPlatform

public class CheckoutTests
{
    [Test("A customer can check out")]
    [Retry(2, DelayMilliseconds = 200)]
    public async Task Checkout()
    {
        var response = await Rest.Post("/orders")
            .WithJsonBody(new { sku = "ABC", quantity = 2 })
            .SendAsync();

        await Assert.That(response).ToHaveStatusAsync(HttpStatusCode.Created);
    }
}

There is no Main and no OutputType to write. The first build leaves a commented precept.json in the project.

One thing a NuGet package cannot do for you: on the .NET 10 SDK, dotnet test has to be told to use Microsoft.Testing.Platform, in a global.json at the repository root — the SDK reads it from the directory dotnet test is run in and upward, not from the project's.

{
  "test": {
    "runner": "Microsoft.Testing.Platform"
  }
}

Without it dotnet test fails with "Testing with VSTest target is no longer supported". Running the test binary directly — dotnet run -- --list-tests — works either way.
