Trying to disable images loading in ChromeDriver. I'm using the following code, however it's still loading the images. Any suggestions?
DesiredCapabilities capabilities = DesiredCapabilities.Chrome();
capabilities.SetCapability("chrome.switches", new string[1] { "disable-images" });
IWebDriver driver = new ChromeDriver(#"C:\chromedriver\", capabilities);
I had the same problem and I found the answer here;
Map<String, Object> contentSettings = new HashMap<String, Object>();
contentSettings.put("images", 2);
Map<String, Object> preferences = new HashMap<String, Object>();
preferences.put("profile.default_content_settings", contentSettings);
DesiredCapabilities caps = DesiredCapabilities.chrome();
caps.setCapability("chrome.prefs", preferences);

I had a couple of cmd line options working with Selenium 3.3 as follows:
`DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities = DesiredCapabilities.Chrome();
options.AddArguments("--lang=en-GB");
options.AddArguments("--high-dpi-support=1");
options.AddArguments("--force-device-scale-factor=0.8");
capabilities = options.ToCapabilities() as DesiredCapabilities;
Driver = new RemoteWebDriver(new Uri("WIN10:5566/wd/hub"), capabilities,
TimeSpan.FromSeconds(180));`
However switching to Selenium 3.5.2, these options are no longer being applied even when using new ToCapabilities() as follows:
ChromeOptions options = new ChromeOptions();
options.AddArguments("--lang=en-GB");
options.AddArguments("--high-dpi-support=1");
options.AddArguments("--force-device-scale-factor=0.5");
Driver = new RemoteWebDriver(new Uri("http://WIN10:5566/wd/hub"), options.ToCapabilities(), TimeSpan.FromSeconds(180));
Is there something else I need?
Try replacing
capabilities = options.ToCapabilities() as DesiredCapabilities;
with the following the following:
capability.setCapability(ChromeOptions.CAPABILITY, options);
Then you only need to specify "capability" in the RemoteWebDriver:
RemoteWebDriver(new URL("your url"), capability);
Thanks smit, that would have worked as well. The problem was the chrome driver needed updating (embarrassed emoji here!)
I am trying to Disable a popup which keeps showing up, which is a "Chrome Extension".
I am attaching a screenshot and also the code.
What I am trying to do is I want to click the Disable button.
The code I am using is:
public static void Initialize()
{
//Instance = new FirefoxDriver();
//Instance = new InternetExplorerDriver(#"C:\Sele2");
ChromeOptions options = new ChromeOptions();
options.AddArguments("--disable-popup-blocking");
var basePath = AppDomain.CurrentDomain.BaseDirectory;
Instance = new ChromeDriver(basePath, options);
Instance.Manage().Timeouts().ImplicitlyWait(TimeSpan.FromSeconds(5));
}
Can someone please help? Thanks in advance
You can add one more arguments as --disable-extensions in your chrome options as below :-
ChromeOptions options = new ChromeOptions();
options.AddArguments("--disable-popup-blocking","--disable-extensions");
var basePath = AppDomain.CurrentDomain.BaseDirectory;
Instance = new ChromeDriver(basePath, options);
Instance.Manage().Timeouts().ImplicitlyWait(TimeSpan.FromSeconds(5));
When I try to use
var dc = DesiredCapabilities.Chrome();
var driver = new ChromeDriver(dc);
I get "Cannot resolve constructor".
It seems like I have to pass ChromeOptions instead.
Why?
Every single tutorial/help page on the subject suggests that I pass DesiredCapabilities.
I am using Selenium.WebDriver.ChromeDriver version 2.21.0.0.
You can use ChromeOptions to set any specific options.
ChromeOptions options = new ChromeOptions();
options.AddArguments("--disable-extensions");
options.AddArguments("--start-maximized");
options.ToCapabilities();
ChromeDriverService service = ChromeDriverService.CreateDefaultService(Environment.GetEnvironmentVariable("USERPROFILE") + "\\Downloads");
IWebDriver chromeDriver = new ChromeDriver(service, options);
You can use- options.ToCapabilities(); to get see the capabilities.
You can use ChromeOptions to set any specific type of capabilities- peter.sh/experiments/chromium-command-line-switches . It seems the DesiredCapabilities can be added only in Java or if you are dealing with InternetExplorerDriver- Selenium c#: How to launch Internet Explorer driver in a specific version (IE8 for example)
Using dotpeek and looking at the chromedriver constructors (which there are 7 overloads) 6 of them invoke the constructor below on the ChromeDriver itself
public ChromeDriver(ChromeDriverService service, ChromeOptions options, TimeSpan commandTimeout)
: base((ICommandExecutor) new DriverServiceCommandExecutor((DriverService) service, commandTimeout), ChromeDriver.ConvertOptionsToCapabilities(options))
{
}
Which in turn calls the base constructor on the RemoteWebdriver. This passes in the last parameter as ChromeDriver.ConvertOptionsToCapabilities(options)
Looking at the you can see this:
private static ICapabilities ConvertOptionsToCapabilities(ChromeOptions options)
{
if (options == null)
throw new ArgumentNullException("options", "options must not be null");
return options.ToCapabilities();
}
Then into options.ToCapabilities:
public override ICapabilities ToCapabilities()
{
Dictionary<string, object> dictionary = this.BuildChromeOptionsDictionary();
DesiredCapabilities desiredCapabilities = DesiredCapabilities.Chrome();
desiredCapabilities.SetCapability(ChromeOptions.Capability, (object) dictionary);
if (this.proxy != null)
desiredCapabilities.SetCapability(CapabilityType.Proxy, (object) this.proxy);
Dictionary<string, object> preferencesDictionary = this.GenerateLoggingPreferencesDictionary();
if (preferencesDictionary != null)
desiredCapabilities.SetCapability(CapabilityType.LoggingPreferences, (object) preferencesDictionary);
foreach (KeyValuePair<string, object> additionalCapability in this.additionalCapabilities)
desiredCapabilities.SetCapability(additionalCapability.Key, additionalCapability.Value);
You can see under the hood it appears its already using DesiredCapabilities.Chrome() and you don't need to pass it in. Perhaps the tutorials you have seen are outdated?
I have software which does automated testing via chrome browser, but now this program failed with error message "Vector smash protection is enabled."
I've found a solution for this case, but this solution implemented via java API.
DesiredCapabilities capabilities = DesiredCapabilities.chrome();
capabilities.setCapability("chrome.switches", Arrays.asList("--incognito"));
ChromeOptions options = new ChromeOptions();
options.addArguments("test-type");
WebDriver driver = new ChromeDriver(capabilities);
How to implement a code the same as above via c#?
You need a Dictionary
// Capabilities Values
var imageSetting = new Dictionary<string, object> {{"images", 2}};
var content = new Dictionary<string, object> {{"profile.default_content_settings", imageSetting}};
var prefs = new Dictionary<string, object> {{"prefs", content}};
// List of Chromium Command Line Switches
var options = new ChromeOptions();
options.AddArguments(
"--disable-extensions",
"--disable-features",
"--disable-popup-blocking",
"--disable-settings-window");
// Add the Capabilities
var field = options.GetType().GetField("additionalCapabilities", BindingFlags.Instance | BindingFlags.NonPublic);
if (field != null)
{
var dict = field.GetValue(options) as IDictionary<string, object>;
if (dict != null) dict.Add(ChromeOptions.Capability, prefs);
}
// Create the Chrome Driver
var chromeDriver = new ChromeDriver(options);
Also you can send the driver path when you create the ChromeDriver object.
How does one disable images in Google chrome when using it through Selenium and c#?
I've attempted 6 ways and none worked. I've even tried the answer on this StackOverflow question, however I think the info in it is out of date.
Chrome driver: V2.2
Chrome version: V29.0.1547.66 m
Selenium: V2.35
All the attempts I've made don't cause exceptions, they run normally but still display images:
Attempt 1:
ChromeOptions co = new ChromeOptions();
co.AddArgument("--disable-images");
IWebDriver driver = new ChromeDriver(co);
Attempt 2:
DesiredCapabilities capabilities = DesiredCapabilities.Chrome();
capabilities.SetCapability("chrome.switches", new string[1] { "disable-images" });
Attempt 3:
ChromeOptions co = new ChromeOptions();
co.AddAdditionalCapability("chrome.switches", new string[1] { "disable-images" });
Attempt 4:
var imageSetting = new Dictionary<string, object>();
imageSetting.Add("images", 2);
Dictionary<string, object> content = new Dictionary<string, object>();
content.Add("profile.default_content_settings", imageSetting);
var prefs = new Dictionary<string, object>();
prefs.Add("prefs", content);
var options = new ChromeOptions();
var field = options.GetType().GetField("additionalCapabilities", BindingFlags.Instance | BindingFlags.NonPublic);
if (field != null)
{
var dict = field.GetValue(options) as IDictionary<string, object>;
if (dict != null)
dict.Add(ChromeOptions.Capability, prefs);
}
Attempt 5:
ChromeOptions options = new ChromeOptions();
options.AddAdditionalCapability("profile.default_content_settings", 2);
Attempt 6:
Dictionary<String, Object> contentSettings = new Dictionary<String, Object>();
contentSettings.Add("images", 2);
Dictionary<String, Object> preferences = new Dictionary<String, Object>();
preferences.Add("profile.default_content_settings", contentSettings);
DesiredCapabilities caps = DesiredCapabilities.Chrome();
caps.SetCapability("chrome.prefs", preferences);
This is my solution
IWebDriver driver;
ChromeOptions options = new ChromeOptions();
options.AddUserProfilePreference("profile.default_content_setting_values.images", 2);
driver = new ChromeDriver(options);
You should use --blink-settings instead of --disable-images by:
options.add_argument('--blink-settings=imagesEnabled=false')
which also works in headless mode. Setting profile doesn't work in headless mode. You can verify it by screenshot:
driver.get_screenshot_as_file('headless.png')
Note: I was using python with selenium, but I think it should be easy to transfer to c#.
For your method 1-3, I don't see a Chrome switch called --disable-images listed here. So even if the code snippets are correct, they won't work no matter what. Where did you get that switch? Any references?
For the methods 4-6, I assume you got the idea from this chromdriver issue. I don't know if this {'profile.default_content_settings': {'images': 2}} is still valid or not, but you can give it a try with the following code (which was originally the answer to How to set Chrome preferences using Selenium Webdriver .NET binding?, answer provided by Martin Devillers).
public class ChromeOptionsWithPrefs: ChromeOptions {
public Dictionary<string,object> prefs { get; set; }
}
public static void Initialize() {
var options = new ChromeOptionsWithPrefs();
options.prefs = new Dictionary<string, object> {
{ "profile.default_content_settings", new Dictionary<string, object>() { "images", 2 } }
};
var driver = new ChromeDriver(options);
}
Use http://chrome-extension-downloader.com/ to download the "Block Image" extension (https://chrome.google.com/webstore/detail/block-image/pehaalcefcjfccdpbckoablngfkfgfgj?hl=en-GB). The extension prevents the image from being downloaded in the first place. Now it's just a matter of loading it using the following statement:
var options = new ChromeOptions();
//use the block image extension to prevent images from downloading.
options.AddExtension("Block-image_v1.0.crx");
var driver = new ChromeDriver(options);
An easier approach would be solely:
ChromeOptions options = new ChromeOptions();
options.addArguments("headless","--blink-settings=imagesEnabled=false");
I found out simple solution. This idea referred from Python:Disable images in Selenium Google ChromeDriver
var service = ChromeDriverService.CreateDefaultService(#WebDriverPath);
var options = net ChromeOptions();
options.AddUserProfilePreference("profile.managed_default_content_settings.images", 2);
IWebDriver Driver = new ChromeDriver(service, options);
I recommend that you create a new profile, customize this profile so that it does not load the images, and use this profile as a chromeOption to set up your driver.
