Implicit and Explicit Waits in selenium with examples

Explicit Wait is related with certain conditions to wait; Implicit Wait with specific time to wait for an Element.


Explicit Wait

Here, the driver waits for 10 secs till the web element is found;  If not, it simply throws a Timeout Exception.

WebElement element = (new WebDriverWait(driver, 10))
  .until(ExpectedConditions.presenceOfElementLocated(By.id("Value")));

or|

WebDriverWait wait = new WebDriverWait(driver, 20);
WebElement element = wait.until(ExpectedConditions.elementToBeClickable(By.id("Value")));


WebDriverWait can't be declared globally and throw NullPointerException; whereas the below snippets will help you to do so.


// Handles any locator
@Test
public void Test01() throws Exception {
  driver.get("www.xyz.com");
  wait().until(ExpectedConditions.presenceOfElementLocated(By.xpath("Value")));
  }

private WebDriverWait wait()
   {
    return new WebDriverWait(driver, 20);
   }


// Handles any locator [This method works for page object pattern]
private WebDriver driver;
private final Wait<WebDriver> wait;

public Classname(WebDriver driver) { //constructor
   this.driver = driver;
   wait = new WebDriverWait(driver, 20);
 }

@Test
public void Test01() throws Exception {
  driver.get("www.xyz.com");
  wait.until(ExpectedConditions.presenceOfElementLocated(By.xpath("Value")));
  }

// Handle the locators by id, name, xpath, css, etc.,
@Test
public void Test02() throws Exception {
  driver.get("www.xyz.com");
  waitForID("Value");
   }

public void waitForID(String id) 
   {         
    WebDriverWait wait = new WebDriverWait(driver, 10);      
    wait.until(ExpectedConditions.presenceOfElementLocated(By.id(id)));      
   }
