Defining a custom step method

If the f and _ methods are not to your taste, it's trivial to define your own synonym(s). E.g.

public static class MyExtensions
{
    public static IStep x(this string text, Action body)
    {
        return text.f(body);
    }

    public static IStep ʃ(this string text, Action body)
    {
        return text.f(body);
    }

    public static IStep σʃσ(this string text, Action body)
    {
        return text.f(body);
    }

    public static IStep 梟(this string text, Action body)
    {
        return text.f(body);
    }

    public static IStep χ(this string text, Action body)
    {
        return text.f(body);
    }
}

Note that to support all types of steps, you should also provide overloads of your custom step method which accept Action<IStepContext>, Func<Task> and Func<IStepContext, Task>. E.g. a full set of x custom step methods would be:

public static class MyExtensions
{
    public static IStep x(this string text, Action body)
    {
        return text.f(body);
    }

    public static IStep x(this string text, Action<IStepContext> body)
    {
        return text.f(body);
    }

    public static IStep x(this string text, Func<Task> body)
    {
        return text.f(body);
    }

    public static IStep x(this string text, Func<IStepContext, Task> body)
    {
        return text.f(body);
    }
}
