• CommandQuery

Support for:

• AspNetCore 🌐
• AWSLambda ⚡
• AzureFunctions ⚡
• GoogleCloudFunctions ⚡

Do you enjoy writing unit tests and are on the lookout for something new?

Check out this quirky little framework:

• LoFuUnit

View example:

public class MoodTests : LoFuTest<MoodIdentifier>
{
    string _mood;

    [LoFu, Test]
    public void Identify_mood_on_mondays()
    {
        void given_the_current_day_is_monday()
        {
            var monday = new DateTime(2011, 2, 14);

            Use<ISystemClock>()
                .CurrentTime
                .Returns(monday);
        }

        void when_identifying_my_mood() =>
            _mood = Subject.IdentifyMood();

        void should_be_pretty_bad() =>
            _mood.Should().Be("Pretty bad");
    }
}

Do you need markup in the frontend?

Generate some HTML in the backend:

        e.title("Markupolation"),
        meta(name("description"), content("Sample of how to use Markupolation")),
        meta(name("viewport"), content("width=device-width, initial-scale=1"))
    ),
    body(
        h1("Hello, World!"),
        p("This is ", mark(a.title("Markup with string interpolation"), "Markupolation"), " in action.")
    )
);

Command functionality

Hi, I have got acquainted with your source code and it is excellent and easy to use library. But for now, there is no opportunity to return result from command. Is it in plat to implement this functionality or no?
