Robot Framework: How to detect Shadow DOM

The Robot Framework is a test automation framework for acceptance testing and acceptance test-driven development (ATDD). It has a keyword-driven approach and allows users to create test cases in a simple, tabular syntax.

The Robot Framework does not have built-in support for testing the Shadow DOM. The Shadow DOM is a browser feature that allows web developers to create and use isolated, reusable elements in their web pages.

It provides a way to encapsulate the internals of an element, making it difficult or impossible to access or modify the element’s contents from outside of the element.

To test elements in the Shadow DOM using the Robot Framework, you would need to use a library that provides support for interacting with the Shadow DOM. One such library is the SeleniumLibrary, which provides keywords for controlling a web browser and interacting with web pages.

Here is an example of how you can use the SeleniumLibrary to test an element in the Shadow DOM using the Robot Framework:

*** Settings ***
Library    SeleniumLibrary
*** Test Cases ***
Test Shadow DOM Element
    Open Browser    http://www.example.com    chrome
    Go To    http://www.example.com/page-with-shadow-dom-element
    Wait Until Element Is Visible    css:my-shadow-dom-element
    ${element}=    Get Shadow Root    css:my-shadow-dom-element
    Log To Console    ${element}
    Should Contain    ${element}    Shadow DOM Element

In this test case, the Open Browser keyword is used to open the Chrome web browser and navigate to the specified URL.

The Wait Until Element Is Visible keyword is used to wait for the specified element to be visible on the page.

The Get Shadow Root keyword is then used to get the shadow root of the specified element, which represents the root of the element’s Shadow DOM subtree.

The shadow root is logged to the console and verified to contain the text “Shadow DOM Element”.

Note that this is just one possible way to test an element in the Shadow DOM using the Robot Framework. The specific details of the test case will depend on the specific requirements of the element and the expected behavior.

More Examples

Here are some more examples of how you can use the SeleniumLibrary to test elements in the Shadow DOM using the Robot Framework:

*** Test Cases ***
Test Shadow DOM Element Text
    Open Browser    http://www.example.com    chrome
    Go To    http://www.example.com/page-with-shadow-dom-element
    Wait Until Element Is Visible    css:my-shadow-dom-element
    ${element}=    Get Shadow Root    css:my-shadow-dom-element
    ${text}=    Get Text    ${element}
    Should Be Equal    ${text}    Shadow DOM Element
Test Shadow DOM Element Attributes
    Open Browser    http://www.example.com    chrome
    Go To    http://www.example.com/page-with-shadow-dom-element
    Wait Until Element Is Visible    css:my-shadow-dom-element
    ${element}=    Get Shadow Root    css:my-shadow-dom-element
    ${attributes}=    Get Element Attributes    ${element}
    Should Contain    ${attributes}    attribute1    attribute2
Test Shadow DOM Element Click
    Open Browser    http://www.example.com    chrome
    Go To    http://www.example.com/page-with-shadow-dom-element
    Wait Until Element Is Visible    css:my-shadow-dom-element
    ${element}=    Get Shadow Root    css:my-shadow-dom-element
    Click Element    ${element}
    Wait Until Element Is Visible    css:my-shadow-dom-element-click-result
    ${result}=    Get Text    css:my-shadow-dom-element-click-result
    Should Be Equal    ${result}    Shadow DOM Element Clicked

In the first test case, the Get Text keyword is used to get the text content of the element in the Shadow DOM. The text is verified to be equal to the expected value.

In the second test case, the Get Element Attributes keyword is used to get the attributes of the element in the Shadow DOM. The attributes are verified to include the expected values.

In the third test case, the Click Element keyword is used to simulate a mouse click on the element in the Shadow DOM. This triggers an event that is handled by the element, and the result of the event is verified using the Get Text and Should Be Equal keywords.

Note that these test cases are just examples, and you may need to modify them to match the specific requirements of your elements and the expected behavior.
