Selenium: waiting for an element disappears

Question

I posed with a difficult task. I am new to selenium and still working on functionality for expecting elements and the like.

I need to manipulate some data on a website and then move on to another. Problem: the manipulation calls a script, which makes a small label "Save ..." while the data being processed is processed in the background. I need to wait until I go to the next website.

So here it is: How am I waiting for the DISAPPEAR element? The thing is this: it is always present in the DOM, but is visible only to some script (I assume, see the image below).

This is what I tried, but it just doesn’t work - there is no waiting, selenium simply proceeds to the next step (and gets stuck with a warning asking me if I want to leave or stay on the page because of "saving ...").

private By savingLableLocator = By.id("lblOrderHeaderSaving");

    public boolean waitForSavingDone(By webelementLocator, Integer seconds){
    WebDriverWait wait = new WebDriverWait(driver, seconds);
    Boolean element = wait.until(ExpectedConditions.invisibilityOfElementLocated(webelementLocator));
    return element;
}

UPDATE / DECISION:

I came up with the following solution: I built my own method. It basically checks for CssValue changes in the loop.

loops check a certain amount of time for the CSSVALUE “display” to transition from the “block” to another state.

public void waitForSavingOrderHeaderDone(Integer _seconds){
    WebElement savingLbl = driver.findElement(By.id("lblOrderHeaderSaving"));   
    for (int second = 0;; second++) {
        if (second >= _seconds)
            System.out.println("Waiting for changes to be saved...");
        try {
            if (!("block".equals(savingLbl.getCssValue("display"))))
                break;
        } catch (Exception e) {

        }
    }

Answer 1

I'm not sure, but you can try something like this :)

driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS); //time in second
WebElement we = driver.findElement(By.id("lblOrderHeaderSaving"));   
assertEquals("none", we.getCssValue("display"));

Webdriver , .

Wait<WebDriver> wait = new FluentWait<WebDriver>(driver)
   .withTimeout(30, SECONDS)
   .pollingEvery(5, SECONDS)
   .ignoring(NoSuchElementException.class);

WebElement foo = wait.until(new Function<WebDriver, WebElement>() {
 public WebElement apply(WebDriver driver) {
   return (driver.findElements(By.id("lblOrderHeaderSaving")).size() == 0);
 }
});

Answer 3

, WebElement StaleElementReferenceException :

public void waitForInvisibility(WebElement webElement, int maxSeconds) {
    Long startTime = System.currentTimeMillis();
    try {
        while (System.currentTimeMillis() - startTime < maxSeconds * 1000 && webElement.isDisplayed()) {}
    } catch (StaleElementReferenceException e) {
        return;
    }
}

2.4.0. mehtod , .

final public static boolean waitForElToBeRemove(WebDriver driver, final By by) {
    try {
        driver.manage().timeouts()
                .implicitlyWait(0, TimeUnit.SECONDS);

        WebDriverWait wait = new WebDriverWait(UITestBase.driver,
                DEFAULT_TIMEOUT);

        boolean present = wait
                .ignoring(StaleElementReferenceException.class)
                .ignoring(NoSuchElementException.class)
                .until(ExpectedConditions.invisibilityOfElementLocated(by));

        return present;
    } catch (Exception e) {
        return false;
    } finally {
        driver.manage().timeouts()
                .implicitlyWait(DEFAULT_TIMEOUT, TimeUnit.SECONDS);
    }
}
