Added Part1Answer and Part2Answer for testing (thanks Pobiega)
https://www.nuget.org/packages/AdventOfCodeSupport/2.3.0

protected override void InternalPart1()
{
    ...
    return 42; // Can be obtained with Part1Answer.
}

[Fact]
public void TestDay01_Returned42_Equals42()
{
    var day = _solutions.GetDay(2023, 1);
    Assert.Equal("42", day.Part1Answer);
}
