Theories

The DSL supports the theory pattern via a name property.

This will become the ToString value and be displayed in the test runner.

using static ArrangeActAssert;
using Test = TestBuilder<ArrangeActAssertSyntax>.Asserted<int, string>;

public static class TheoryTests
{
    public static readonly TheoryData<Test> TestCases = Enumerable
        .Range(1, 10)
        .Select(i =>
            (i.Arrange() with { Name = $"{i} can be converted to a string" })
                .Act(x => x.ToString(InvariantCulture))
                .Assert(r => Assert.Equal($"{i}", r))
        )
        .Aggregate(
            new TheoryData<Test>(),
            (td, s) =>
            {
                td.Add(s);
                return td;
            }
        );

    [MemberData(nameof(TestCases))]
    public static Task Case1(Test scenario) => scenario;
