Check if PowerBI page is loaded (using Selenium)

Hi!

I am using Selenium to automate load and performance testing of PowerBI reports and I need a reliable way to pause code execution until page is fully loaded (all queries executed and all slicers and charts displayed). Many pages on Google suggested I should use following JavaScripts codes to achieve that:

• return jQuery.active == 0
• return document.readyState == "complete"

But this does not work for me as both lines are always verified as true and code continues executing although I can see that chart has not been drawn.

The only way I could made it work is to get XPaths of all elements from the report (slicers, charts, etc.) and wait for all of those elements to "become"visible:

public void waitUntilReportProcesses(IWebDriver driver)
{
	WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(600.00));
	var xpaths = new string[]
	{
		"//*[@id=\"pvExplorationHost\"]/div/div/div/div[1]/div[2]/div[3]/div[2]/div[2]", // chart 1
		"//*[@id=\"pvExplorationHost\"]/div/div/div/div[1]/div[2]/div[9]/div[2]/div[2]", // chart 2
		"//*[@id=\"pvExplorationHost\"]/div/div/div/div[1]/div[2]/div[6]/div[2]/div" // slicer 1
		//...
	};

	foreach (var xpath in xpaths)
		wait.Until(ExpectedConditions.ElementIsVisible(By.XPath(xpath)));
}

I tried to make above code more universal by finding elements using css (By.CssSelector). With that approach I am able to get all of the necessary elemets but ElementIsVisible and VisibilityOfAllElementsLocatedBy methods seems to behave differently in that case and code never pauses execution.

What would be the proper way to check if PowerBI page has been loaded?

Thanks,
