========== Starting test discovery ==========
Test project TerminalGuiFluentTestingXunit does not reference any .NET NuGet adapter. Test discovery or execution might not work for this project.
It's recommended to reference NuGet test adapters in each test project in the solution.

I just noticed there are 2 csproj files. I think this is a remnant due to bad refactor I made. Think we can actually delete `TerminalGuiFluentTesting.Xunit` as I renamed it just `TerminalGuiFluentTestingXunit` (no dot).

XunitContextExtensions.cs files on both are different.

In TerminalGuiFluentTesting.Xunit:

using Xunit;

namespace TerminalGuiFluentTesting;

public static class XunitContextExtensions
{
    public static GuiTestContext AssertTrue (this GuiTestContext context, bool? condition)
    {
        context.Then (
                      () =>
                      {
                          Assert.True (condition);
                      });
        return context;
    }
    public static GuiTestContext AssertEqual (this GuiTestContext context, object? expected, object? actual)
    {
        context.Then (
                      () =>
                      {
                          Assert.Equal (expected,actual);
                      });
        return context;
    }
}

In TerminalGuiFluentTestingXunit:

using TerminalGuiFluentTesting;
using Xunit;

namespace TerminalGuiFluentTestingXunit;

public static partial class XunitContextExtensions
{
    // Placeholder
}

It's secure delete the TerminalGuiFluentTesting.Xunit folder then?

[tznind]

Yes, the placeholder is correct one - code gen builds all the relevant methods at build time
