I'm trying to use Azure WebApps, with Webjobs, to Test applications.
Locally, it works great. But when I build to cloud it happens the problem listed above.
Apperently the file was found, but it stays wainting until timeout.
Does anybody knows how to solve this?
I'm using C# Selenium WebDriver.
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using System;
using System.Diagnostics;
using System.IO;
namespace Ololu_WebJob
{
class Program
{
static void Main()
{
IWebDriver driver = new ChromeDriver();
driver.Url = "my_url";
Console.WriteLine(driver.Title);
driver.Quit();
}
}
}

Per my experience, you can not directly use selenium and chromedriver without an installed instance of Chrome or Chromium on Azure WebApp, as the requirement of ChromeDriver Setup said below.
Ensure Chromium/Google Chrome is installed in a recognized location
ChromeDriver expects you to have Chrome installed in the default location for your platform. You can also force ChromeDriver to use a custom location by setting a special capability.
However, due to some restricts of Azure WebApp sandbox which include Win32k.sys (User32/GDI32) Restrictions and Local Address Requests, you could not start Chrome or Chromium without GDI support via chromedriver even if you uploaded a portable distribution of Chrome or Chromium into Azure WebApp and configured environment variables.
Although your error information did not point out the real reason of the issue in your C# code, I got the error information in Python on Azure WebApp as below.
So a workaround way is to directly use selenium and chromedriver on Azure VM. Or considering for your scenario, you can start chromedriver on default port 9515 on Azure VM and configure the VM NSG role to allow the inbound of port 9515, then to use class OpenQA.Selenium.Remote.RemoteWebDriver to connect the remote webdriver in Azure WebJob.
Here is a sample code for using RemoteWebDriver which comes from C# (CSharp) OpenQA.Selenium.Remote RemoteWebDriver.FindElement Examples
IWebDriver webDriver = new RemoteWebDriver(new Uri("http://<vm host ip>:9515"), DesiredCapabilities.Chrome());

...implies that the ChromeDriver was unable to initiate/spawn a new Browsing Context i.e. Chrome Browser session.
Possibly your main issue is the incompatibility between the version of the binaries you are using as the ChromeDriver version is not getting detected:
Driver info: driver.version: unknown
Solution
Ensure that:
ChromeDriver is updated to current ChromeDriver 97.0.4692.71 level.
Chrome is updated to current chrome=Version 97.0.4692.71 (as per chrome=97.0.4692.71 release notes).
The Issue:
Perform the following steps to recreate the issue:
cd C:\Temp
New-Item -ItemType Directory -Name init-db-issue
cd .\init-db-issue
# Download ASP.NET Core sample projects
Invoke-WebRequest -Uri https://codeload.github.com/dotnet/AspNetCore.Docs/zip/main -OutFile main.zip
# Expanding takes a while
Expand-Archive -Path .\main.zip
cd .\main\AspNetCore.Docs-main\aspnetcore\security\authorization\secure-data\samples\final3
dotnet user-secrets set SeedUserPW Secret123!
# Drop the database in case it already exists
sqlcmd -S "(localdb)\MSSQLLocalDB" -Q "DROP DATABASE [aspnet-ContactManager-02]"
At this point, do not load the project in vs or vscode. Simply run the project from a PowerShell prompt:
dotnet run
Here's what I get on my system:

Note the following part:

An error occurred seeding the DB.
System.AggregateException: One or more errors occurred. (Value cannot be null. (Parameter 'password'))
Now, load the project in vs but do not run it from there:
Start-Process .\ContactManager.csproj
Run the app from the PowerShell prompt:
dotnet run
Now I don't get the message An error occurred seeding the DB and the DB is indeed seeded.
Question:
Why does the issue go away when we simply load the project into Visual Studio? I would expect the project to work fine when running it via dotnet run without needing to also run Visual Studio. Is this a bug? Or is it due to some aspect of how the project is setup?
The project can be viewed here.
This project is the example used in the following tutorial:
Create an ASP.NET Core web app with user data protected by authorization
The issue is that Properties/launchSettings.json does not exist.
See this comment:
https://github.com/dotnet/AspNetCore.Docs/issues/21668#issuecomment-795543707
Here's a minimal test case which demonstrates the issue:
cd C:\Temp

cd init-db-issue-new-app
dotnet new webapp -o ContactManager -au Individual -uld
cd .\ContactManager

}
public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.ConfigureWebHostDefaults(webBuilder =>

});
}
}
"# | Set-Content .\Program.cs

When the application is published on windows it works perfectly. I am not using SQLite, I´m using SqlServer.

I am trying to run selenium UI tests through vsts release pipeline usingVisual Studio Test tasks from vsts release. My tests are getting recognized but not getting executed. getting same error for all tests.
I have tried updating the chrome drive used the old chrome driver still no luck. Initially I was using the chromedrive.exe file in my sln but then I removed that and add a nuget reference form Selenium.Chrome.Webdriver 2.45. tests are running fine on my local machine but when I deploy on vsts agent server I am getting an error
this the error I am getting in my VsTest log

driver.Navigate().GoToUrl(url);
driver.Manage().Window.Size = new Size { Width = 1920, Height = 1080 };

}
In my prior tries I was getting same error for Maximize() code.
This is was added in mu csproj after the nuget addition
<Import Project="..\packages\Selenium.Chrome.WebDriver.2.45\build\Selenium.Chrome.WebDriver.targets" Condition="Exists('..\packages\Selenium.Chrome.WebDriver.2.45\build\Selenium.Chrome.WebDriver.targets')" />
and this in packages.

I want to Run the selenium tests In my VSTS pipeline using the Visual Studio Test. Also I have Visual Studio Test Platform Installer task prior to test execution task in my pipeline and my tests are getting recognized successfully.
I tried most of the available solution but still the same error. hence asking again.
The error message indicates that the agent you are running the UI tests on can't reach the URL you've specified.
Are you using a hosted agent in the release pipeline in AzDO? If so, it won't have line of sight to your localhost URL. Check that by changing your URL to google.com or bing.com and it should be able to run the test successfully.
Install a self-hosted agent on your machine instead: https://learn.microsoft.com/en-us/azure/devops/pipelines/agents/agents?view=azure-devops#install
Or follow this: https://www.azuredevopslabs.com/labs/vstsextend/selenium/.
You'll want to make sure that the appropriate NuGet packages for Selenium are also getting restored but I don't think that's specifically related to this error you're getting.
I created an application that use Selenium using .NetCore for use it on Linux, actually this is my code implementation:
public class Program
{
public static async Task Main(string[] args)
{
//Settings for chrome
var chromeOpts = new ChromeOptions();
chromeOpts.AddArgument("headless");
chromeOpts.AddArgument("no-sandbox");
//Get assembly path where chrome driver is located
string codeBase = Assembly.GetExecutingAssembly().CodeBase;
UriBuilder uri = new UriBuilder(codeBase);
string path = Uri.UnescapeDataString(uri.Path);
path = Path.GetDirectoryName(path);
var driver = new ChromeDriver(path, chromeOpts, TimeSpan.FromSeconds(180));
}
}
as you can see I am using as driver Chrome, I downloaded it here, I also added the driver inside the folder of the assembly, in this way the ChromeDriver knows already where to search it.
On linux I changed the folder permission using chmod -R 777, but when I run my Dotnet application I get this:
Seems that Selenium cannot start the application.
Looking at the Exception I get:
Cannot find Chrome binary
Unfortunately I didn't find anything similar on the web, someone could help me?
Thanks in advance.
UPDATE
I Just reinstalled Chrome on my linux machine and now the error above went away, but there is another problem now, infact I get this error:
OpenQA.Selenium.WebDriverException: unknown error: Chrome failed to start: exited abnormally (Driver info: chromedriver=2.9.248304,platform=Linux 4.4.0-130-generic x86_64)

This error message...
OpenQA.Selenium.WebDriverException: unknown error: Chrome failed to start: exited abnormally
...implies that the ChromeDriver was unable to initiate/spawn a new WebBrowser i.e. Chrome Browser session.
Your main issue is the incompatibility between the version of the binaries you are using as follows:
You are using chromedriver=2.9 which is pretty ancient.
So there is a clear mismatch between the ChromeDriver version (v2.33) and the recent Chrome Browser version (vVersion 68.0)
Solution
Upgrade ChromeDriver to current ChromeDriver v2.41 level.
Keep Chrome version between Chrome v67-69 levels. (as per ChromeDriver v2.41 release notes)
Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
If your base Web Client version is too old, then uninstall it through Revo Uninstaller and install a recent GA and released version of Web Client.
Execute your #Test.
