nUnit attribute [Retry] does not work in my test

Question

I am very new to nUnit testing I try to use nUnit attributes and in my code [Retry] does not work when Assert fails. I am using Microsoft Visual Studio Professional 2022 Current Version 17.6.2 NuGet packages: Selenium.WebDriver, Selenium.Support, Selenium.Chrome.WebDriver, Gherkin, NUnit, NUnit3TestAdapter

I use in Assert method wrong title (see "Attention! WrongTitle so that Assertion will fail") to make assertion fail.

the code is:

using NUnit;
using NUnit.Framework;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using OpenQA.Selenium.DevTools.V113.CSS;
using System;


namespace TestThePage
{
    [TestFixture]
    public class NavigateToTheWepPage
    {
       
        private IWebDriver driver;

        public IWebDriver theDriver
        {
            get { return driver; }
            set { driver = value; }
        }

        string url = "https://www.Some Web Site I Use to Experiment With nUnit";

        [OneTimeSetUp]
        public void InitaliseSmth()
        {
            var options = new ChromeOptions();
            driver = new ChromeDriver();
            options.AddArgument("--no-sandbox");
            options.AddArgument("start-maximized");
            options.AddUserProfilePreference("disable-popup-blocking", "true");
        }

        [Test]
        [Retry(2)]
        public void CallSomeTest()
        {
            //Step 1: Navigate through couple of pages
            OpenSomePage(url);
            IWebElement element = theDriver.FindElement(By.XPath("/html/body/div[8]/header/div[2]/div[1]/div[1]/nav/ul/li[5]/a/span[1]"));
            element.Click();
            IWebElement element1 = theDriver.FindElement(By.XPath(".//*[@id=\"orb-modules\"]/header/div[2]/div[1]/div[1]/nav/ul/li[6]/a/span[1]"));
            element1.Click();
            
            //element2.Click();
            string currentPageTitle = theDriver.Title;

            // Step 2 Assert you have an expected content on the page you navigated to 
            try
            {
                Assert.IsTrue(currentPageTitle.Contains("Attention! WrongTitle so that Assertion will fail"));
                TestContext.WriteLine("Word \"World\" was found in the header");
            }
            catch (Exception ex)
            { 
                TestContext.WriteLine("Word \"World\" was NOT found in the header");
                if (ex is AssertionException)
                Console.WriteLine($"Processing failed: {ex.Message}");

            }
        }

        public void OpenSomePage(string url)
        { 
            theDriver.Url = url;
        }
    }
}

I would expect that when assertion fails, so because I have [Retry(2)] it would try to run the code again. However, when I run the code it just fails for the first time and would NOT try to execute again. Is it my wrong expectation about [Retry(2)] ,or I am doing something wrong?

Answer 1

In my code I changed [TearDown] to [OneTimeTearDown] and it is working now. It was just closing the driver before the second attempt.

using NUnit;
using NUnit.Framework;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using OpenQA.Selenium.DevTools.V113.CSS;
using System;


namespace TestThePage
{
    [TestFixture]
    public class NavigateToTheWepPage
    {
       
        private IWebDriver driver;
        //public IWebDriver Driver => driver;

        public IWebDriver theDriver
        {
            get { return driver; }
            set { driver = value; }
        }

        readonly string url = "https://Some web site url";
        int count = 0;

        [OneTimeSetUp]
        public void InitaliseSmth()
        {
            var options = new ChromeOptions();
            driver = new ChromeDriver();
            options.AddArgument("--no-sandbox");
            options.AddArgument("start-maximized");
            options.AddUserProfilePreference("disable-popup-blocking", "true");
        }

        [Test]
        [Retry(2)]
        [Category("PracticenUnit")]
        public void CallSomeTest()
        {
            //Step 1: Navigate through couple of pages
            OpenSomePage(url);
            IWebElement element = theDriver.FindElement(By.XPath("/html/body/div[8]/header/div[2]/div[1]/div[1]/nav/ul/li[5]/a/span[1]"));
            element.Click();
            IWebElement element1 = theDriver.FindElement(By.XPath(".//*[@id=\"orb-modules\"]/header/div[2]/div[1]/div[1]/nav/ul/li[6]/a/span[1]"));
            element1.Click();
         
            string currentPageTitle = theDriver.Title;

            // Step 2 Assert you have an expected content on the page you navigated to
            try
            {
                TestContext.Progress.WriteLine("Here it is in try assertion, count: {0}", ++count);
                Assert.IsTrue(currentPageTitle.Contains("Attention! WrongTitle so that Assertion will fail"));
                TestContext.Progress.WriteLine("Here it is AFTER Assertion");
              
            }
            catch
            {
                TestContext.Progress.WriteLine("In the catch");
            }

            // Step 3 return to the previous page
            ReturnToThePreviousPage();
        }

       
        public void OpenSomePage(string url)
        { 
            theDriver.Url = url;
        }

        public void ReturnToThePreviousPage()
        {
            theDriver.Navigate().Back();
        }

        //[TearDown]
        // public void closeBrowser()
        //{
        //theDriver.Close();
        //}

        [OneTimeTearDown]
        public void closeBrowser()
        {
            theDriver.Close();
        }
    }
}

Now it is running twice before the program is closed, see the Output:
