    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
