How can I handle dynamic WebElements in Java test cases?

Hey Punamhans,

Use dynamic XPath or CSS Selectors to handle WebElements whose attributes change frequently. Implement waits (explicit, implicit, or fluent) to synchronize your tests with the web application’s state.

To learn more about how to write test cases in Java, follow the blog below and get detailed insights.

Handling StaleElementReferenceException: Dynamic web elements may be removed or replaced in the DOM, leading to a StaleElementReferenceException. To handle this, you can implement a retry mechanism that re-fetches the element when such an exception occurs.

public WebElement getElementWithRetry(By locator) {
    int retries = 3;
    while (retries > 0) {
        try {
            return driver.findElement(locator);
        } catch (StaleElementReferenceException e) {
            retries--;
        }
    }
    throw new NoSuchElementException("Element not found after retries.");
}

This method attempts to find the element up to 3 times, handling cases where the element is dynamically refreshed or replaced in the DOM.

JavaScript Executor for Stable Interactions: When traditional methods fail due to dynamic content, using JavaScript to interact with web elements can offer more control. JavaScriptExecutor can help click or scroll into view for elements that appear dynamically.

WebElement dynamicElement = driver.findElement(By.id("dynamicElementId"));
JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("arguments[0].scrollIntoView(true);", dynamicElement);
js.executeScript("arguments[0].click();", dynamicElement);

This approach uses JavaScript to scroll to the element and interact with it, ensuring more reliable handling of dynamic web elements.
