fixes #3194

#if DEBUG
        internal static string BuildCurrentState(string done, char current, string todo)
            => $"done: '{done}'.   current: '{current}'.   todo: '{todo}'";
        internal string CurrentState
        {
            get
            {
                var current = (char)Peek();
                if (Position < 0 || Position > Text.Length)
                {
                    return BuildCurrentState(done: "INVALID_CURRENT_STATE", current: char.MaxValue, todo: "INVALID_CURRENT_STATE");
                }
                var done = Substring(0, Position);
                var todo = ((Position < _text.Length) ? Text.Substring(Position) : "");
                return BuildCurrentState(done: done, current: current, todo: todo);
            }
        }

Need to change the config * .yml,
The tests only work for the release configuration now.
It is necessary to run only debug tests as well
dotnet tests --filter displayName~Debug

It is necessary to run only debug tests as well

Well the code is only activated when making DEBUG-builds. For release-builds then the code is non-existing.

[lobster2012-user]

That's right, but the test result is not obvious. At your discretion.
For dev branch you can also run debug tests.

[snakefoot]

The AppVeyor-build runs the final code-coverage test using a DEBUG-build for proper symbol-information.

Thanks for the PR!

The build fails, see this error:

Missing headers (copy them form other another file).
1 errors:

-C:\projects\nlog\tests/NLog.UnitTests\SimpleStringReaderDebugViewTests.cs

Could you please fix this? Thanks 😊

Thanks, looks good, but please do some renames and a file move - see notes. Then I could merge it :)

[lobster2012-user]

I fixed all and changed the logic of todo.

[304NotModified]

Thanks! Merged! :)
