Example of using a step argument transform to convert text to an enum value

step_argument_transform.cs

[StepArgumentTransformation(@"from (A-Z|Z-A)")]
public SortOrder SortOrderTransform(string sortOrderPhrase)
{
    if (sortOrderPhrase == "Z-A")
        return SortOrder.Descending;
 
    return SortOrder.Ascending;
}

[When(@"I sort by product name (.*)")]
public void WhenISortByProductName(SortOrder sortOrder)
{
    _products.Sort((s1, s2) =>
    {
        if (sortOrder == SortOrder.Descending)
            return s1.ProductName.CompareTo(s2.ProductName) * (-1);

        return s1.ProductName.CompareTo(s2.ProductName);
    });

    int i = 1;
    _products.ForEach(p => p.Index = i++);
}
