Extension methods to create dynamic objects from SpecFlow tables

SpecFlow.Assist.Dynamic

Just to be clear - I rather have this whole project in SpecFlow core - but couldn't make that happen due to the solution I'm using and it's dependencies which didn't play nicely with signed assemblies :(

This file is just a teaser... Be sure to check-out the documentation (https://github.com/marcushammarberg/SpecFlow.Assist.Dynamic/wiki/Documentation)

SpecFlow.Assist.Dynamic is a couple of simple extension methods for the SpecFlow Table object that helps you to write less code.

What would you rather write? This:

[Binding]
public class StepsUsingStaticType
{
    private Person _person;
 
    [Given(@"I create an instance from this table")]
    public void GivenICreateAnInstanceFromThisTable(Table table)
    {
        _person = table.CreateInstance<Person>();
    }

    [Then(@"the Name property on Person should equal '(.*)'")]
    public void PersonNameShouldBe(string expectedValue)
    {
        Assert.AreEqual(expectedValue, _person.Name);
    }

}

public class Person
{
    public string Name { get; set; }
    public int Age { get; set; }
    public DateTime BirthDate { get; set; }
    public double LengthInMeters { get; set; }
}

Or this:

[Binding]
public class StepsUsingDynamic
{
    private dynamic _instance;
 
    [Given(@"I create a dynamic instance from this table using step argument transformation")]
    public void c(dynamic instance)
    {
        _instance = instance;
    }

    [Then(@"the Name property should equal '(.*)'")]
    public void NameShouldBe(string expectedValue)
    {
        Assert.AreEqual(expectedValue, _instance.Name.ToString());
    }
}

The later version uses SpecFlow.Assist.Dynamic. Shorter, sweater and more fun!
