Explicit wait (WebDriverWait) in Selenium Java - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is an explicit wait in Selenium WebDriver?

An explicit wait tells WebDriver to wait for a certain condition to happen before continuing. It waits for a specific element or condition for a set time.

How do you create an explicit wait using WebDriverWait in Java?

You create a WebDriverWait object with the driver and timeout, then use it with ExpectedConditions to wait for a condition, like this:<br>

WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(10));<br>wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("elementId")));

Why is explicit wait better than Thread.sleep()?

Explicit wait waits only as long as needed for a condition, making tests faster and more reliable. Thread.sleep() always waits the fixed time, which can slow tests and cause failures.

intermediate

What happens if the condition in WebDriverWait is not met within the timeout?

If the condition is not met in the given time, WebDriverWait throws a TimeoutException, which means the test will fail at that point.

Give an example of waiting for an element to be clickable using explicit wait.

Example:<br>

WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(15));<br>WebElement button = wait.until(ExpectedConditions.elementToBeClickable(By.cssSelector("button.submit")));
button.click();

What does WebDriverWait do in Selenium?

A Waits for a specific condition before proceeding

B Pauses the test for a fixed time

C Closes the browser after test completion

D Finds elements without waiting

WebDriverWait waits for a condition like element visibility or clickability before continuing.

Which exception is thrown if WebDriverWait times out?

A TimeoutException

B StaleElementReferenceException

C ElementNotVisibleException

D NoSuchElementException

TimeoutException is thrown when the wait condition is not met within the timeout.

Which method is used with WebDriverWait to wait for an element to be visible?

A ExpectedConditions.elementToBeClickable()

B ExpectedConditions.visibilityOfElementLocated()

C ExpectedConditions.presenceOfElementLocated()

D ExpectedConditions.invisibilityOfElement()

visibilityOfElementLocated waits until the element is visible on the page.

Why is explicit wait preferred over implicit wait?

A Implicit wait throws exceptions

B Implicit wait is faster

C Explicit wait is deprecated

D Explicit wait waits for specific conditions, implicit wait waits for all elements

Explicit wait targets specific conditions, making tests more precise and reliable.

How do you specify the timeout duration in WebDriverWait in Java?

A Using a String value

B Using an int value in seconds

C Using Duration.ofSeconds()

D Using a boolean flag

In modern Selenium Java, Duration.ofSeconds() is used to set the timeout.

Explain how to use explicit wait with WebDriverWait to wait for an element to become clickable.

Think about waiting for a button before clicking it.

Describe the difference between explicit wait and implicit wait in Selenium.

Consider how each wait affects test speed and reliability.
