Click via an Extension in Virtuoso

Article Overview:

This article will cover how you can achieve the following:

Perform a click action on an element using a custom extension when the native mouse click NLP is not compatible with the AUT.

Problem Statement:

If the Native Mouse click NLP in Virtuoso is not compatible with the AUT, making it difficult to perform a click action during test execution.

Solution:

1. Using Virtuoso's Native Mouse Action NLP: The standard command to perform mouse actions in Virtuoso is: mouse click "Element" If the AUT supports this command, it will execute the click action on the specified element.
   

2. Custom Extension for  Click Action: If the native click NLP is incompatible, you can use the following custom JavaScript extension to simulate the click action:
   

function ClickByXPath(xpath) {
    const element = document.evaluate(xpath, document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue;
    if (element) {
        const event = new MouseEvent('click', {
            bubbles: true,
            cancelable: true,
            view: window
        });
        element.dispatchEvent(event);
    } else {
        console.error('Element not found for the provided XPath.');
    }
}
return ClickByXPath(xpath);

1. Usage:

   • Step 1: Identify the XPath of the element you wish to click on.
   • Step 2: Pass the XPath into the code using the extension parameter ExtClick(xpath).
   • Step 3: Call the ExtClick extension into the journey to perform the click action.
   • Optional: To perform a double click, use the mouse event as 'dblclick' on line 4 of the code above.

Examples:

Here's how we call the specific extension:
