No longer supported in Selenium 4.x

[kathyrollo]

[TestCleanup]
public void TearDown()
{
    if (TestContext.CurrentTestOutcome == UnitTestOutcome.Failed)
    {
        var maker = new ScreenshotMaker();
        maker.RemoveScrollBarsWhileShooting();
        var vertical = new VerticalCombineDecorator(maker);
        var sshot = driver.TakeScreenshot(vertical);
        var fileName = $"{TestContext.TestResultsDirectory}/sshot_{DateTimeOffset.Now.ToUnixTimeMilliseconds()}.png";
        File.WriteAllBytes(fileName, sshot);
        TestContext.AddResultFile(fileName);
    }
    driver.Quit();
}

No compile error but the same code that used to work with Selenium 3.141.0 no longer saves screenshots after updating to Selenium 4.0.1.

I'll check it in a few days

[Noksa]

I've tested it and I can't reproduce this error. File was saved to a directory in this line: File.WriteAllBytes(fileName, sshot);

[kathyrollo]

@Noksa Thanks for looking into it. What was the exact Selenium version you used?

[Noksa]

@kathyrollo I used the latest version from nuget. It was 4.1.0

[kathyrollo]

@Noksa Thanks, this was observed in 4.0.1. Will check with the latest version to see if it replicates and update.

Seems like this is the proper place to post this as I'm also having issues with 4.x.

When calling WDSE.ExtensionMethods.TakeScreenshot(this IWebDriver driver, IScreenshotStrategy strategy) I get this exception: System.TypeLoadException: 'Could not load type 'OpenQA.Selenium.Remote.CapabilityType' from assembly 'WebDriver, Version=4.0.0.0, Culture=neutral, PublicKeyToken=null'.'

It looks like CapabilityType was moved to the OpenQA.Selenium namespace

I would like to report the same issue

For us a workaround solution was to downgrade Selenium.WebDriver and Selenium.Support to v4.0.0

[Noksa]

Can someone share a sample project where it reproduces every time? I would very appreciate because I can't reproduce it.

The reason for failing for me was that I did not have Selenium.Support in my solution. And seems like the version from your solution (3.8.0) was used.

Adding <PackageReference Include="Selenium.Support" Version="4.1.0" /> to my solution fixed the issue.

So updating Selenium.WebDriver and Selenium.Support versions to 4.1.0 in your solution should probably fix the issue.

[Noksa]

Yeah, that's why I wrote this message: https://github.com/Noksa/WebDriver.Screenshots.Extensions/issues/27#issuecomment-983457976

[shatulsky]

Yea, but to reproduce the issue you can just create an empty project and reference only Selenium.WebDriver 4.1.0 and your NuGet package. That is was you asking for, right?

I still have the same issue after I downgraded from V4.11.x to V3.14.1. I'm not sure where I can add " Adding '<PackageReference Include="Selenium.Support" Version="4.1.0" /'> to my solution fixed the issue. So updating Selenium.WebDriver and Selenium.Support versions to 4.1.0 in your solution should probably fix the issue. "

[updated] I had trouble with the nuget package versions mapping tables while downgrade and upgrade nuget installations. I had to search to understand shatulsky's comments and it helped me solve it.

[sirphilliptubell]

So I confirmed adding Selenium.Support (with the proper version) fixes the issue.

Here's a scenario

• The .csproj references WDSE v2.14.1
  • which references v3.8 of Selenium.Support and Selenium.WebDriver
• The .csproj references Selenium.WebDriver only (v4.3.0)
• You call driver.TakeScreenshot(new VerticalCombineDecorator(new ScreenshotMaker()));
  • That calls WDSE.ScreenshotMaker.ScreenshotMaker.MakeScreenshot()
  • That calls OpenQA.Selenium.Support.Extensions.WebDriverExtensions.TakeScreenshot(this IWebDriver driver) - now this extension (in the Selenium.Support package) needs CapabilityType which is in the Selenium.WebDriver package
  • But the nuget packages that are actually running are:
    • Selenium.WebDriver 4.3
    • Selenium.Support 3.8 (via the WDSE package transitively because you didn't specify it in the .csproj)
    • The CapabilityType was moved to a new namespace from 3.x to 4.x, so Selenium.Support can't find CapabilityType in that namespace anymore

The other fix would be to add a new WDSE version (say 4.0) that has a dependency on 4.x of the Selenium packages - that way it's clear you need a WDSE 4.x if you're using Selenium 4.x. Otherwise people will continue to get the latest WSDE and Selenium.WebDriver packages only and get this error.

@Noksa here's an example

  <ItemGroup>
    <PackageReference Include="Noksa.WebDriver.ScreenshotsExtensions" Version="0.1.5.4" />
    <PackageReference Include="Selenium.WebDriver" Version="4.3.0" />
    <PackageReference Include="WebDriverManager" Version="2.14.1" />
  </ItemGroup>

using OpenQA.Selenium.Chrome;
using OpenQA.Selenium.Support.Extensions;
using WDSE;
using WDSE.Decorators;
using WDSE.ScreenshotMaker;
using WebDriverManager;
using WebDriverManager.DriverConfigs.Impl;

new DriverManager().SetUpDriver(new ChromeConfig());
var driver = new ChromeDriver();
driver.Navigate().GoToUrl("https://slashdot.org");
// throws
var screenshot = driver.TakeScreenshot(new VerticalCombineDecorator(new ScreenshotMaker()));

Hi @Noksa ,

I confirm it works with the following latest versions (as of this writing):

I'm closing the ticket unless you deem otherwise. Thanks.
