How to automate shadow DOM elements with Selenium?

#2

Hi Toby,

When attempting to locate Shadow DOM elements through Selenium locators, a NoSuchElementException is encountered since it is not directly reachable within the DOM.

To overcome this limitation, the following approaches can be employed to access Shadow DOM locators:

  1. Using the getShadowRoot() method of Selenium WebDriver.
  2. Employing JavaScriptExecutor for indirect access.

You can refer to the following blog, for more detail.

Hey Toby,

You can use CSS Selectors: If you know the shadow host element’s CSS selector, you can use JavaScript to access its shadow root and then locate the shadow DOM elements within it. Here’s an example:

WebElement shadowHost = driver.findElement(By.cssSelector(“your-shadow-host-css-selector”)); WebElement shadowRoot = (WebElement) ((JavascriptExecutor) driver).executeScript(“return arguments[0].shadowRoot”, shadowHost); WebElement shadowElement = shadowRoot.findElement(By.cssSelector(“your-shadow-element-css-selector”));

let me know if you have further any questions

Hey Toby,

The other way to automate shadow DOM is using querySelector in JavaScriptExecutor you can directly execute JavaScript code to find the shadow DOM elements. Here’s an example:

WebElement shadowElement = (WebElement) ((JavascriptExecutor) driver).executeScript(“return document.querySelector(‘your-shadow-element-css-selector’)”);

The above method allow you to access and interact with shadow DOM elements in Selenium.
