Why is it better to use explicitly wait rather than implicitly wait in Selenium Web Driver?

Hi Friend,

Totally different concept for explicit wait and implicit wait.

When Implicit wait defined, selenium waits for every element on page or screen to become available before it throws NoSuchElementExeception.

And Explicit wait is, when selenium waits for certain condition before performing any action on WebElement.

Now see advantage of using explicit wait,where we can create WebbElement in different ways. For example

WebDriverWait wait = new WebDriverWait(driver, 50);

element=wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("loginButton"))); element=wait.until(ExpectedConditions.presenceOfElementLocated(By.id("loginButton")));

element=wait.until(ExpectedConditions.elementToBeClickable(By.id("loginButton")));

You can also see other implementations of these methods in webdriver API

Now please see, how Webdriver methods can be used to wait dynamically for any element using these explicit wait methods. All of the below methods return boolean ie true if element is found otherwise false.

Attribute Validation

wait.until(ExpectedConditions.attributeContains(By.cssSelector("box"),"name","txt"));

wait.until(ExpectedConditions.attributeToBe(By.cssSelector("box"),"name","txt1"));

wait.until(ExpectedConditions.attributeToBeNotEmpty(element,"name"));

Waiting for Elements Count

wait.until(ExpectedConditions.numberOfElementsToBe(By.cssSelector("box"),5));

wait.until(ExpectedConditions.numberOfElementsToBeLessThan(By.cssSelector("box"),5));

wait.until(ExpectedConditions.numberOfElementsToBeMoreThan(By.cssSelector("box"),5));

Waiting for a text in an element

wait.until(ExpectedConditions.textMatches(By.cssSelector("box"),Pattern.compile("(.*)(\\d+)(.*)")));

wait.until(ExpectedConditions.textToBe(By.cssSelector("box"),"Sample"));

Waiting for a title of the page

boolean flag = wait.until(ExpectedConditions.titleIs(title));

boolean flag = wait.until(ExpectedConditions.titleContains(title));
