How to wait until all loaders disappears using Selenium WebDriver through Java

问题

I am using selenium web driver and I need to wait until all loaders disappear. I have 12 widgets on dashboard page and I need to wait until all widgets are loaded. Loader shows on each widget. I have used both following ways but nothing works and no errors, it just passes on to next statement.

new WebDriverWait(driver,60)
.until(ExpectedConditions.invisibilityOfElementLocated(By.xpath("//div[contains(text(),'Loader')]"))); 

WebDriverWait wait2 = new WebDriverWait(driver,60);
wait2.until(ExpectedConditions.invisibilityOfElementLocated(By.cssSelector("div.loader")));

回答1:

As you are having total 12 widgets on dashboard page and you need to wait until all widgets are loaded you have to induce WebDriverWait for the invisibilityOfAllElements() and you can use either of the following Locator Strategies:

• cssSelector:

  new WebDriverWait(driver, 20).until(ExpectedConditions.invisibilityOfAllElements(driver.findElements(By.cssSelector("div.loader"))));
  

• xpath:

  new WebDriverWait(driver, 20).until(ExpectedConditions.invisibilityOfAllElements(driver.findElements(By.xpath("//div[@class='loader']"))));
