I have created NUnit suite that initialises Chrome Webdriver in Selenium. This works fine with InternetExplorer driver and Firefox driver however fails with SerializationException every time I try to run it with Chrome driver.
Anyone can point me in right direction?
namespace TestNamespace
{
using System;
using NUnit.Framework;
using NUnit.Core;
using SeleniumTests;
using OpenQA.Selenium;
using OpenQA.Selenium.IE;
using OpenQA.Selenium.Firefox;
using OpenQA.Selenium.Chrome;
using OpenQA.Selenium.Support.UI;
class AllInOne
{
public static IWebDriver WebDriver { get; private set; }
[Suite]
public static TestSuite Suite
{
get
{
TestSuite suite = new TestSuite("All Tests");
SetupChrome();
suite.Add(new FlashLoadedTest { Driver = WebDriver });
return suite;
}
}
private static void SetupChrome()
{
WebDriver = new ChromeDriver(#"C:\Users\<username>\AppData\Local\Google\Chrome\Application");
}
}
}
This is error I get:

I am not into NUnit, but I believe that IWebDriver class is for Internet Explorer only - but that applies to Java
Do you have class WebDriver also? If yes, try using it.

I had the same issue, it is stated that it will be fixed with the next version. Ticket - https://github.com/SeleniumHQ/selenium/issues/9483
I encountered this issue with selenium 4.0.0-beta-3
I am new to this WCF stuff and I need to get the project involving WCF at work. So, I am testing the water by creating a very simple wcf using NetTcpBinding hardcoding the ip address to simplify the configuration but I was not able to get it to work. Please take a look and see if there is something that jumps at you, I would appreciate it if you could point me to something I have done incorrectly.
I have a WCFLib, WCFHost and WCFClient. If everything is on the same machine, it is fine and dandy and the client and host worked perfect and the result was correct. However, If the host is on one machine and the client on a different one in the same subnet no firewall (the client could ping the host successfully) and I tried to run the client then click the "=" button in the application, I got this error:
See the end of this message for details on invoking

I have developed an WCF Service Library that uses Agatha RRSL, but I can not figure out how to initialize the container. If I recreate this service in an ASP.NET Web Application, I can call the initialization code from the Global.asax.cs Application_Start() and everything works perfectly. The initialization code is:
public static class ComponentRegistration
{
public static void Register()
{
new ServiceLayerConfiguration(Assembly.GetExecutingAssembly(),
typeof(HelloWorldRequest).Assembly,
typeof(Agatha.Castle.Container)).Initialize();
}
}
In the WCF Service Library, I added an App_Code folder with a class that calls:
public static void AppInitialize()
{
ComponentRegistration.Register();
}
That didn't work as my client app throws an exception that there is no response with that type. I also tried adding a component to the web.config file, but I never got that even close to working.
I also tried to create a custom ServiceHost that does the initialization:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.ServiceModel;
using System.ServiceModel.Activation;
using Agatha.ServiceLayer;
using System.Reflection;
using Sample.Common.RequestsAndResponses;
namespace Sample.ServiceLayer.WCFHost
{
public class CustomServiceHostFactory : ServiceHostFactory
{
public CustomServiceHostFactory()
{
new ServiceLayerConfiguration(Assembly.GetExecutingAssembly(), typeof(HelloWorldRequest).Assembly,
typeof(Agatha.Castle.Container)).Initialize();
}
protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses)
{
return new CustomServiceHost(serviceType, baseAddresses);
}
}
public class CustomServiceHost : ServiceHost
{
public CustomServiceHost()
{
}
public CustomServiceHost(Type serviceType, params Uri[] baseAddresses)
: base(serviceType, baseAddresses)
{
}
protected override void OnOpening()
{
base.OnOpening();
}
protected override void OnClosing()
{
base.OnClosing();
}
protected override void ApplyConfiguration()
{
base.ApplyConfiguration();
}
}
}
However, I get the same exception on my client:
System.InvalidOperationException was unhandled
Message=There is no response with type Sample.Common.RequestsAndResponses.HelloWorldResponse. Maybe you called Clear before or forgot to add appropriate request first.

What approach should I take to get the WCF Service Library to run my initialization code so that the host returns the correct type?
Any guidance would be much appreciated.

What could be the possible reason when I unit test Postgresql, it results to RemotingException: Unix transport error. ?
If I run the code outside of unit test (e.g. Main), it works. Btw, if I unit test Sqlite, it doesn't cause any errors too
Found the answer, I tried launching MonoDevelop from Terminal (/Applications/MonoDevelop.app/Contents/MacOS/monodevelop), I saw the more detailed error from the commandline when I ran the unit tests.

Lesson learned, use the Mono version of the component you are using if you are running things on Mono
This exception occurs, when a unit test in MonoDevelop raises an exception, which could not be caught by the test runner (i.e. when the test starts some threads and they crash).
If you have such a test which is grey even after running
and the unit test pad shows the internal error
you should try running the test on your console with nunit-console (should be in the repo of your distro where mono comes from) and leak the exception.
In my case it was a simple multiple enumeration exception in a sub-thread of my test.

I have just tried this code in my Console Application and it worked:
using System.Management.Automation.Runspaces;
using Microsoft.PowerShell;
namespace TryConsoleShell
{
class Program
{
static void Main(string[] args)
{
var config = RunspaceConfiguration.Create();
ConsoleShell.Start(config, "Windows PowerShell", "help text", new string[] { "-noexit", "ls" });
}
}
}
I guess your application is Windows Application and this scenario is either not supported at all or you still have to have a console window available (I have not tried this way yet).
EDIT:
It worked in WinForm Application as well. But the console window is still needed for the console host. To make the console window available just change the project output type to Console Application.

using System.Windows.Forms;
using Microsoft.PowerShell;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
var config = RunspaceConfiguration.Create();
ConsoleShell.Start(config, "Windows PowerShell", "help text", new string[] { "-noexit", "ls" });
}
}
}
P.S. I have never seen use of this scenario in practice and did not even know that it actually works. Are there some practically useful applications of it?
