What happens if an element is not located within the time frame of explicit wait in Selenium?
It will throw an exception
What role do 'Waits' play in executing tests in Selenium?
They prevent 'ElementNotVisibleException' exceptions
Why are 'Waits' necessary in Selenium?
To handle time intervals for element loading
What problem do 'Waits' in Selenium help resolve?
Locating elements when they load at different intervals
What happens if an element is not located within the time frame defined by explicit wait?
It switches to implicit wait time frame
Where has Selenium Web Driver borrowed the idea of implicit waits from?
Watir
What does an implicit wait of 10 seconds mean?
The test will wait for 10 seconds for an element to be located before throwing an exception
What problem do implicit and explicit waits help resolve in Selenium?
Preventing 'ElementNotVisibleException' exceptions
What exception is thrown if the element is not located within the time frame defined by explicit wait?
TimeoutException
What is the consequence of setting an implicit wait time frame longer than the explicit wait time frame?
The explicit wait will wait for the specified time frame, then the implicit wait will take over
What is the purpose of an explicit wait in Selenium?
To wait for a specific condition to be met before proceeding
What is the consequence of not using any waits in Selenium?
The test will fail due to element identification issues
What type of exceptions can be prevented by using Selenium Waits?
All of the above
Study Notes
Implicit Wait
- Accepts time in seconds as a parameter
- Waits for elements to load within the set time frame before throwing a NoSuchElementException
Explicit Wait
- Waits for a specific condition to occur before proceeding with execution
- Used with ExpectedConditions to check for specific conditions
- Throws a TimeoutException if the condition is not met within the set time frame
- Should be used with a WebDriverWait and ExpectedConditions to check the condition
Fluent Wait
- Example:
Wait fluentWait = new FluentWait(driver).withTimeout(30, TimeUnit.SECONDS).pollingEvery(5, TimeUnit.SECONDS); - Maximum time frame set: 30 seconds
- Frequency set: 5 seconds
Importance of Waits
- Play a crucial role in executing tests by handling synchronization issues
- Necessary to handle page loading and element rendering times
- Help resolve synchronization issues and timeout exceptions
- Prevent NoSuchElementException and TimeoutException
Consequences
- Not using waits can lead to test failures and unreliable tests
- Setting implicit wait time frame longer than explicit wait time frame can lead to longer test execution times
- If an element is not located within the time frame defined by explicit wait, a TimeoutException is thrown
