What is Implicit Wait in Selenium?

Implicit Wait sets a default timeout for the WebDriver to poll the DOM repeatedly until an element is found, before throwing NoSuchElementException.

How to set:

driver.manage().timeouts().implicitlyWait(Duration.ofSeconds(10));

How it works:

1. ✓You call driver.findElement(By.id("btn"))
2. ✓WebDriver polls the DOM for up to 10 seconds
3. ✓If found before 10s → proceeds immediately
4. ✓If not found in 10s → throws NoSuchElementException

Key characteristics:

• ✓Set once per driver session — applies globally
• ✓Polls at approximately 500ms intervals
• ✓Applies only to findElement() and findElements()
• ✓Does NOT work with ExpectedConditions

Example:

driver.manage().timeouts().implicitlyWait(Duration.ofSeconds(10));
driver.get("https://automateqa.online");
WebElement el = driver.findElement(By.id("result")); // Waits if not immediately available

Warning: Mixing implicit and explicit waits can cause unpredictable wait times. Choose one strategy per project.
