Here’s how you can resolve this:

Steps Description
Checking Chrome Version To begin, first find out your chrome browser’s version. Go to ‘help > about Google chrome’.
Download Compatible Chromedriver Now download the compatible Chromedriver from here, for your browser version.
Chrome Options You can pass chrome options to ignore such adapter errors by disabling GPU.

To utilize Chrome options, just like we indicated in our third step on the table, here’s a snippet that can change how Chrome behaves when launched via Selenium:

from selenium import webdriver
from selenium.webdriver.chrome.service import Service

# Add options to ignore default adapter failed error by disabling GPU
options = webdriver.ChromeOptions()
options.add_argument('--disable-gpu')

driver = webdriver.Chrome(service=Service('path-to-your-chromedriver'), options=options)
driver.get("http://www.your-website.com")

In our code snippet above, we import necessary modules from Selenium, set our options to disable GPU (which has helped bypass the ‘Default Adapter Failed’ error for many users), then initialize our webdriver with these options, and finally navigate to our desired webpage.

Be sure to replace ‘path-to-your-chromedriver’ with the path to your downloaded `chromedriver` executable. This should take care of the ‘Getting Default Adapter Failed’ error when launching Chrome and navigating to a website using the Chromedriver via Selenium.Sure, I would love to shed some light on this common error that software developers and testers often stumble upon while using Selenium WebDriver with Chrome: “Getting Default Adapter Failed”.

This error typically appears when you try to initiate a WebDriver session in order to automate Google Chrome. Although it’s a straightforward error indicating a communication breakdown between the ChromeDriver and the Chrome Browser, the reasons behind such issue could be multiple.

from selenium import webdriver

driver = webdriver.Chrome(executable_path='/path/to/chromedriver')
driver.get('http://www.google.com')

If you encounter the “Getting Default Adapter Failed” error upon executing the above script, here’re some possible root causes and solutions:

Compatibility Issues

One common reason behind this error relates to compatibility issues between the Chromedriver and the Google Chrome browser.

* If you’re running an older version of Chromedriver with a newer version of Chrome (or vice versa), you may confront this type of error.

Solution: Always ensure both your Chromedriver and Chrome Browser are compatible. You can find information about which versions of Chrome are supported by each version of Chromedriver on the ChromeDriver download page. Once you determine the correct version for your setup, download it and replace the existing one.

Happy coding!When you’re navigating the world of Selenium for webpage accessibility and testing, one common hurdle that might be encountered is the ‘Getting default adapter failed’ error when launching Chrome using the Chromedriver. This issue usually rises due to an incompatibility between the versions of Chrome browser and Chromedriver, or due to some misconfiguration.

from selenium import webdriver

driver = webdriver.Chrome()
driver.get("https://www.google.com")

In this given example, if an error happens with a message displaying ‘getting default adapter failed’, it’s vital to know how to troubleshoot and resolve it. Fortunately, there are several methods to tackle these situations:

Update Your Chromedriver: Selenium servers typically require third-party drivers to interface with browsers and steering the Chromedriver is considered as an integral aspect. However, each version of the Chromedriver supports different ranges of Chrome browser versions. Therefore, in order to avoid aforementioned error, try updating your Chromedriver to match the version of your Chrome browser.

Maintain Consistent Binaries Version: In other cases, an incorrect installation or configuration might cause the ‘Getting default adapter failed’ problem. Confirm both Google Chrome and Chromedriver binaries are installed to expected paths, and that these paths are correctly configured in your system’s Environment Variables.

Ensure Browser Compatibility: While keeping up-to-date with the latest Chromedriver and browser version aids in preventing a myriad of problems, it must also be ensured that the specific version of chromedriver is compatibility with the installed browser version.
One way to do is by referring to official Chromedriver downloads page, which lists supported browser versions per Chromedriver version.

For example in python;

from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager

driver = webdriver.Chrome(ChromeDriverManager(version="88.0.4324.96").install()) # adjust according to own chrome version
driver.get('http://www.google.com');

Adopt Virtual Environments: Using virtual environments can take care of package management isolating requirements needed by particular projects or tests. For instance, Python’s venv module lets you create self-contained ‘Environments’ with their own Python binaries and isolated package versions — ensuring that dependencies won’t conflict. This approach might help if your issue persists across multiple environments.

In conclusion, understanding how the individual parts of your testing environment interact is a crucial part of ensuring functional automated tests. Tools like Selenium do much of the heavy lifting, but proper setup and maintenance of your testing configurations is equally important.

Why does this happen?

To function efficiently, Selenium WebDriver needs the platform-specific Chromedriver. However, if the Chromedriver’s version doesn’t match or support the existing Google Chrome browser version installed on your machine, it leads to the ‘Getting Default Adapter Failed’ error. It results from:

  • The discrepancy in the versions of your Chromedriver and Chrome Browser.
  • Chromedriver is designed for stable Chrome versions. If you have a beta or unstable variant of the Chrome browser, the compatibility problem might arise.

Correcting these issues will likely solve your problem. Below are the steps you can take to rectify the situation.

Check Your Chrome Browser Version

First, check your Google Chrome browser’s version number. To get this information, open your Chrome browser and type ‘chrome://version’ into the address bar. The details of the current browser, including the version, will be displayed.

Check Your Chromedriver Version

The next step is to verify the version of your Chromedriver. You can do this by executing the Chromedriver file through the command line as follows:

./chromedriver

Above, DOT signifies the current directory where the chromedriver executable is located. Replace “chromedriver” with the respective filename in your system.

Ensure Compatibility Between The Chromedriver and Chrome Browser Versions

Compare the obtained browser and Chromedriver versions. They should comply with each other. For instance, for Chrome Browser v89.x.y.z, you should use Chromedriver 89.y.z (y,z – might not exactly match as per official Chromium documentation).

Update Your Chromedriver If Required

If your versions aren’t compatible, you’ll have to update your Chromedriver. To install the matching Chromedriver, use the official Chromedriver downloads page. Download the correct version that matches your installed Chrome Browser, extract, and replace the older one.

With these steps completed, your Selenium tests should now successfully launch Google Chrome and access webpages without encountering the ‘Getting Default Adapter Failed’ error.

This problem may stem from using an outdated version of Chromedriver that’s incompatible with your Chrome Browser. So, it’s necessary to keep your Chromedriver up-to-date. To ensure that you’re using a compatible driver-version pair, you can consult the official compatibility documentation

# Download the latest version of Chromedriver
driver = webdriver.Chrome(ChromeDriverManager().install())

Verifying Chromedriver Installation Path

Sometimes ‘Getting Default Adapter failed’ error arises when the system property isn’t set correctly. It might be due to the missing path specification while setting the WebDriver. You need to specify the exact path where the Chromedriver resides in your system while setting the WebDriver.

System.setProperty("webdriver.chrome.driver", "your\\path\\to\\chromedriver.exe");
WebDriver driver = new ChromeDriver();

Upgrading/Downgrading Chrome Browser Version

If you have recently updated Chromedriver but are still facing this issue, it might be because the current version of the web browser installed on your machine has compatibility issues with the updated driver. Check if there is an upgrade available for the browser. If it still does not solve the issue, consider downgrading to an older stable version.

Use Capabilities to Ignore Not Available Errors

Selenium provides DesiredCapabilities functionality, which enables you to customize and manage browser properties. You could use it to ignore these kinds of errors:

html
DesiredCapabilities capabilities = DesiredCapabilities.chrome();
// Use FLAG to ignore the error
capabilities.setCapability(“chrome.switches”, Arrays.asList(“–ignore-certificate-errors”));
System.setProperty(“webdriver.chrome.driver”,”path/to/chromedriver”);
WebDriver driver = new ChromeDriver(capabilities);

Disabling Extensions

In some situations disabling all Chrome extensions can be helpful. For this:

  • Right-click the extension icon on the toolbar.
  • Go to Manage Extensions.
  • Toggle off the button to disable the extensions.

Then try running your selenium script again.

Remember, the above practices are just starting points. Configuration setups differ and what works for one might not work for another. Always keep track of changes and updates with respect to Selenium, Chromedriver, and your operating system to effectively troubleshoot such common issues. Happy coding!
