Not able to call method from class

Question

I have a class named test.cs:

using Microsoft.VisualStudio.TestTools.UnitTesting;
using OpenQA.Selenium;
using OpenQA.Selenium.Support.PageObjects;
using qa.WrapperFactory;

namespace Common.PageObjects
{
    public class Test
    {
        [FindsBy(How = How.XPath, Using = "xpath")]
        private IWebElement foundElement;

        [FindsBy(How = How.XPath, Using = "xpath")]
        private IWebElement EnvironmentLogoElement;

        [FindsBy(How = How.XPath, Using = "xpath")]
        private IWebElement UsernameElement;

        [FindsBy(How = How.Id, Using = "xpath")]
        private IWebElement PasswordElement;

        public void Setup()
        {
            // Set window to full screen
            BrowserFactory.Driver.Manage().Window.Maximize();
            // Clear all cookies
            BrowserFactory.Driver.Manage().Cookies.DeleteAllCookies();
        }

        public void CheckLoginPage ()
        {
            WaitMethods.WaitForShort(() => foundElement.Displayed);
            Assert.IsTrue(UsernameElement.Displayed);
            Assert.IsTrue(PasswordElement.Displayed);
        }

    }
}

I want to call the method public void CheckLoginPage () from the specflow steps. that looks like this:

using System.Configuration;
using Common.PageObjects;
using qa.WrapperFactory;
using TechTalk.SpecFlow;

namespace RegressionTest
{
    [Binding]
    public class SmokeTestSteps
    {
        [Given(@"I go to the HRControlnet login page")]
        public void GivenIGoToTheHRControlnetLoginPage()
        {
            BrowserFactory.InitBrowser("Firefox");
            var subDomain = ConfigurationManager.AppSettings["Environment"];
            BrowserFactory.LoadApplication(subDomain);
        }

        [Then(@"the result should be on the screen")]
        public void ThenTheResultShouldBeOnTheScreen()
        {
            Test.CheckLoginPage();
        }
    }
}

I get now the error on the step ThenTheResultShouldBeOnTheScreen() with Error CS0120 An object reference is required for the non-static field, method, or property.

I tried to make CheckLoginPage () a static but then all the xpaths give an error.

Anyone can help me out on how to fix this?

You just have to initialize the class and call the method something like below:

  public void ThenTheResultShouldBeOnTheScreen()
    {
        new Test().CheckLoginPage();
    }

This works. But when I execute the test I get the following error in Tests.cs: object reference not set to an instance of an object. – Tester2019 Jan 23 '19 at 10:28
Either `WaitMethods` or `Assert` is null you might want to check this https://stackoverflow.com/questions/779091/what-does-object-reference-not-set-to-an-instance-of-an-object-mean – FreakyAli Jan 23 '19 at 10:54

public void ThenTheResultShouldBeOnTheScreen()
{
    Test test = new Test() // initialize new instance of class
    test.CheckLoginPage()  // call method
}

If this doesn't work, you need to add reference
