等待元素可见性，而不是使用Neustar WPM加载页面

Question

I am trying to write a Neustar WPM script to measure the time taken from clicking a button to the appearance of a button in a overlay that opens. The script looks something like below.

var webDriver = test.openBrowser();
var selenium = webDriver.getSelenium();

webDriver.get('https://www.mywebsite.com');
selenium.waitForPageToLoad(30000);

// Start logging HTTP traffic and timings
test.beginTransaction();    

test.beginStep("Open SignUp");
selenium.click("link=Sign Up");
selenium.waitForElementPresent("name=nextStep");
test.endStep();

test.endTransaction(); 

The problem I am facing is that click does not return immediately and waits for the overlay to completely load. However I want to stop as soon as desired element is visible. How can I ensure that selenium.click return immediately instead of waiting till entire page is loaded.

Answer 1

you can try using this Java method,

public WebElement waitForVisibilityOfElementLocatedBy(final By locator) { return waitFor(visibilityOfElementLocated(locator)); }

public static ExpectedCondition<WebElement> visibilityOfElementLocated(final By locator) {
    return new ExpectedCondition<WebElement>() {
        public WebElement apply(WebDriver driver) {
            try {
                return ExpectedConditions.elementIfVisible(ExpectedConditions.findElement(locator, driver));
            } catch (StaleElementReferenceException var2) {
                return null;
            }
        }

        public String toString() {
            return "visibility of element located by " + locator;
        }
    };
}`
