Running the JavaScript code on a webpage using Selenium WebDriver

I am currently in the process of creating an automated test for a website, and I am encountering some difficulty trying to execute a specific function within the site's code.
Upon inspecting the developer tools, I have identified the function I need to run, and when I trigger alert('hello world') from my script, I can see it working on the test page.
Here is the snippet of my code:

WebDriver driver = getDriver();
JavascriptExecutor js = (JavascriptExecutor) driver;
String retval = (String) js.executeScript("return theFunction()");

However, despite following this approach, I seem to be missing something. Can anyone pinpoint what might be wrong with my implementation?

Answer №1

When working with GWT, it is important to properly declare and reveal functions before using them. For detailed instructions on how to do this, refer to this resource in the Creating JavaScript libraries with GWT section.

To make a function accessible, you must "publish" it by utilizing the following syntax:

$wnd.publishedFuncName = @pakage.class::realfuctionName(D);

Here, D represents a double input parameter. Refer to this guide for more information on variable references.

Once this setup is complete, you can execute the function without needing to reference window.fuction. Additionally, consider changing the data type of retval to Object and utilize the toString function as needed.
