Equivalent of waitForVisible/waitForElementPresent in Selenium WebDriver tests using Java?
Implicit and Explicit Waits
Implicit Wait
An implicit wait is to tell WebDriver to poll the DOM for a certain amount of time when trying to find an element or elements if they are not immediately available. The default setting is 0. Once set, the implicit wait is set for the life of the WebDriver object instance.
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
Explicit Wait + Expected Conditions
An explicit waits is code you define to wait for a certain condition to occur before proceeding further in the code. The worst case of this is Thread.sleep(), which sets the condition to an exact time period to wait. There are some convenience methods provided that help you write code that will wait only as long as required. WebDriverWait in combination with ExpectedCondition is one way this can be accomplished.
WebDriverWait wait = new WebDriverWait(driver, 10);
WebElement element = wait.until(
ExpectedConditions.visibilityOfElementLocated(By.id("someid")));
WebElement myDynamicElement = (new WebDriverWait(driver, 10))
.until(ExpectedConditions.presenceOfElementLocated(By.id("myDynamicElement")));
This waits up to 10 seconds before throwing a TimeoutException or if it finds the element will return it in 0 - 10 seconds. WebDriverWait by default calls the ExpectedCondition every 500 milliseconds until it returns successfully. A successful return is for ExpectedCondition type is Boolean return true or not null return value for all other ExpectedCondition types.
WebDriverWait wait = new WebDriverWait(driver, 10);
WebElement element = wait.until(ExpectedConditions.elementToBeClickable(By.id("someid")));
Element is Clickable - it is Displayed and Enabled.
