BeforeScenario and AfterScenario hooks not working in specflow - selenium

Question

I have the following code in my SeleniumSteps.cs code
I am trying to get the AfterScenario to fire on debugging these tests
using PrivateDomain;
using Machine.Specifications;
using NUnit.Framework;
using OpenQA.Selenium;
using OpenQA.Selenium.Support.UI;
using System;
using System.Collections.Generic;
using System.Drawing.Imaging;
using System.IO;
using System.Linq;
using TechTalk.SpecFlow;
namespace Functional.Steps
{
public class SeleniumSteps : PrivateDomain.Steps.SeleniumSteps
{
#region Hooks
[BeforeScenario]
public void Before()
{
// before
}
[AfterTestRun, Scope(Tag = null)]
public new static void AfterTestRun()
{
// after testrun
}
[AfterScenario]
public void AfterScenarioErrorScreenshot()
{
// after scenario
}
#endregion
}
}
using OpenQA.Selenium;
using TechTalk.SpecFlow;
namespace PrivateDomain.Steps
{
[Binding]
[Scope(Tag = "Selenium")]
public class SeleniumSteps
{
protected static IWebDriver webDriver;
public SeleniumSteps();
public virtual IWebDriver WebDriver { get; }
[AfterTestRun]
[Scope(Tag = null)]
public static void AfterTestRun();
[AfterScenarioAttribute(new[] { })]
public virtual void AfterScenario();
}
}
My feature file looks like this:
(Details removed)
#Customer_Portal
Feature: Account Management - Registration
In order to create an account
As a customer
I want to register my details with the application
Scenario: Register
# Registration Form
When I navigate to "/Customer/Account/Register"
// more code...
Scenario: Required Fields
// more code...
Scenario: Invalid Contact Details
// more code...
Scenario: Insufficient Password Strength
// more code...
Scenario: Password Mismatch
// more code...
Scenario: Already Registered
// more code...
Scenario: Invalid Activation
// more code...
Scenario: Already Activated
// more code...
When I debug a test, I can see the debugger hitting the AfterTestRun portion.
However, neither the BeforeScenario or the AfterScenario are being exercised.
Can someone tell me what I'm doing wrong?

Answer 1

First, as Sandesh noted in his answer, you are missing [Binding] attribute for your SeleniumSteps subclass. It's not enough to have [Binding] only in base class, you must apply it to every class where are your hook methods or step definitions (bindings), because that is the way how specflow is searching for hooks and bindings under the hood. It is like scope identifier. If you miss to place [Binding] attribute to class, specflow will not search for potential hook methods or bindings in that class. Link on documentation: https://specflow.org/documentation/Hooks/
This link can be useful also. Check answer given by RunOfTheShipe: Specflow test step inheritance causes "Ambiguous step definitions"

Answer 2

You have missed [Binding] attribute in your SeleniumSteps
namespace Functional.Steps
{
[Binding]
public class SeleniumSteps : PrivateDomain.Steps.SeleniumSteps
{
#region Hooks
[BeforeScenario]
public void Before()
{
// before
}
}
}
