Author Topic: NUnit crash problem when used with Selenium Webdriver in Visual Studio 2010 [C#] (Read 816 times)

Hi,

I am using Selenium Webdriver with NUnit to test a web application. I have set-up a class library project, and I am loading the .dll into NUnit to run the tests.

This setup is working fine, when I build the solution in VS, then load the DLL in NUnit, and click RUN test cases.

The problem starts when I go back to VS, makes some changes and build the solution again. [Which creates a new .DLL]. As soon as this is done, and I go back to Nunit, it stops working and crashes. I have re-open NUnit, load the solution DLL again and then the tests run fine.

I know that I am missing a simple thing somewhere, but I can't find what. I would appreciate if someone could help me with this.

Hi,

Here is a sample code I have used and it works with Nunit.

Code: [Select]

using System;
using System.Text;
using System.Text.RegularExpressions;
using System.Threading;
using NUnit.Framework;
using OpenQA.Selenium;
using OpenQA.Selenium.Firefox;
using OpenQA.Selenium.Support.UI;

namespace SeleniumTests
{
    [TestFixture]
    public class Untitled
    {
        private IWebDriver driver;
        private StringBuilder verificationErrors;
        private string baseURL;

        [SetUp]
        public void SetupTest()
        {
            driver = new FirefoxDriver();
            baseURL = "http://www.google.com.au/";
            verificationErrors = new StringBuilder();
        }

        [TearDown]
        public void TeardownTest()
        {
            try
            {
                driver.Quit();
            }
            catch (Exception)
            {
                // Ignore errors if unable to close the browser
            }
            Assert.AreEqual("", verificationErrors.ToString());
        }

        [Test]
        public void TheUntitledTest()
        {
            driver.Navigate().GoToUrl(baseURL + "/");
            driver.FindElement(By.Name("q")).Clear();
            driver.FindElement(By.Name("q")).SendKeys("google webdriver");
            Thread.Sleep(10000);
            driver.PageSource.Contains("Google Webdriver");            
        }
        private bool IsElementPresent(By by)
        {
            try
            {
                driver.FindElement(by);
                return true;
            }
            catch (NoSuchElementException)
            {
                return false;
            }
        }
    }
}

Also see the screen shot to integrate nunit for debugging just in-case you have missed.

I would also suggest you have a look at this solution http://www.seleniumwiki.com/visual-studio-2010/selenium-2-webdriver-example-using-visual-studio-test-project/

Instead of creating a class library you will create a test project. Check the screen shot.

Let me know if you have any issues. All the best.

Thank you for your help. The problem with NUnit crash is resolved now. The problem was with NUnit settings for Assembly Isolation.
After selecting the option 'Run Tests in a single separate Process' it worked fine.
It was defaulted to 'Run tests directly in the NUnit process' before.

I will take a look at using the Test project in Visual studio to run the tests. I have never done it before, so I am a little skeptical.

I will get back to you with any further questions I might have.

thank you again for your help.
