[SOLVED] How to automate shadow DOM elements using selenium?

How to automate shadow DOM elements using selenium?

I am using Java Selenium project for web page automation. The web page contains lots of multi-level shadow-root DOM elements that I am not able to interact with using selenium findElement method.

I have tried the following solutions:

deep css (Don't work on latest chrome browser)
JS Executor. (This is really tedious and becomes complex to maintain)

Note:

If you know any other solution other than listed above that I can implement in Selenium Java framework , please pass on the solution. Thanks in advance !.

Solution

There is a very good plugin that can be used with selenium project shadow-automation-selenium. It helps in writing much better, readable and maintainable code. Using this you can access multi level of shadow DOM (up to 4 levels). This uses simple css selector to identify elements.

WebElement findElement(String cssSelector) : use this method if want single element from DOM

List<WebElement> findElements(String cssSelector) : use this if you want to find all elements from DOM

WebElement findElements(WebElement parent, String cssSelector) : use this if you want to find a single elements from parent object DOM

List<WebElement> findElements(WebElement parent, String cssSelector) : use this if you want to find all elements from parent object DOM

WebElement getShadowElement(WebElement parent,String selector) : use this if you want to find a single element from parent DOM

List<WebElement> getAllShadowElement(WebElement parent,String selector) : use this if you want to find all elements from parent DOM

boolean isVisible(WebElement element) : use this if you want to find visibility of element

boolean isChecked(WebElement element) : use this if you want to check if checkbox is selected

boolean isDisabled(WebElement element) : use this if you want to check if element is disabled

String getAttribute(WebElement element,String attribute) : use this if you want to get attribute like aria-selected and other custom attributes of elements.

void selectCheckbox(String label) : use this to select checkbox element using label.

void selectCheckbox(WebElement parentElement, String label) : use this to select checkbox element using label.

void selectRadio(String label) : use this to select radio element using label.

void selectRadio(WebElement parentElement, String label) : use this to select radio element from parent DOM using label.

void selectDropdown(String label) : use this to select dropdown list item using label (use this if only one dropdown is present or loaded on UI).

void selectDropdown(WebElement parentElement, String label) : use this to select dropdown list item from parent DOM using label.

How to use this plugin: You will have to dependency in your project.

Maven

<dependency>
  <groupId>io.github.sukgu</groupId>
  <artifactId>automation</artifactId>
  <version>0.0.4</version>
<dependency>

for html tag that resides under a shadow-root dom element

<properties-page id="settingsPage"> 
  <textarea id="textarea">
</properties-page>

You can use this code in your framework to grab the textarea element Object.

import io.github.sukgu.*;
Shadow shadow = new Shadow(driver);
WebElement element = shadow.findElement("properties-page#settingsPage>textarea#textarea");
String text = element.getText();
