Expected conditions in Selenium Python - Cheat Sheet & Quick Revision

Recall & Review

What are Expected Conditions in Selenium?

Expected Conditions are predefined rules or states that Selenium waits for before continuing test execution, like waiting for an element to be visible or clickable.

Why do we use Expected Conditions instead of fixed waits?

Expected Conditions wait only as long as needed for a condition to be true, making tests faster and more reliable than fixed waits which pause for a set time regardless of readiness.

Name three common Expected Conditions in Selenium.

1. element_to_be_clickable<br>2. visibility_of_element_located<br>3. presence_of_element_located

How do you use Expected Conditions with WebDriverWait in Selenium Python?

You create a WebDriverWait object with a timeout, then call its until() method with an Expected Condition to wait until that condition is met or timeout occurs.

What happens if an Expected Condition is not met within the timeout?

Selenium throws a TimeoutException, indicating the condition was not fulfilled in time, which usually causes the test to fail.

Which Selenium class is used to wait for Expected Conditions?

A WebDriverSleep

B WebDriverWait

C ExpectedWait

D WaitCondition

WebDriverWait is the Selenium class designed to wait for Expected Conditions.

What does the Expected Condition 'element_to_be_clickable' check for?

A Element is hidden

B Element is present in the DOM

C Element is visible and enabled so it can be clicked

D Element has a specific text

'element_to_be_clickable' waits until the element is visible and enabled for clicking.

What exception is raised if an Expected Condition times out?

A NoSuchElementException

B ElementNotVisibleException

C StaleElementReferenceException

D TimeoutException

TimeoutException is raised when the wait exceeds the specified timeout without the condition being met.

Why is using Expected Conditions better than using time.sleep()?

A Expected Conditions wait only as long as needed, making tests faster and more reliable

B time.sleep() is faster

C Expected Conditions ignore element states

D time.sleep() waits for conditions automatically

Expected Conditions wait dynamically until the condition is met, unlike time.sleep() which waits a fixed time.

Which Expected Condition waits for an element to be present in the DOM but not necessarily visible?

A presence_of_element_located

B invisibility_of_element

C element_to_be_clickable

D visibility_of_element_located

'presence_of_element_located' waits for the element to exist in the DOM regardless of visibility.
