How do you switch back to the main page from an iFrame in Selenium?

Use driver.switchTo().defaultContent() to return to the main page from any iFrame.

Which Selenium method is used to switch to an iFrame?

A driver.findElement()

B driver.switchTo().window()

C driver.get()

D driver.switchTo().frame()

driver.switchTo().frame() changes the context to the specified iFrame.

What argument can you NOT pass to switchTo().frame()?

A CSS selector string

B Frame name or ID (String)

C WebElement representing the frame

D Frame index (int)

You cannot pass a CSS selector string directly to switchTo().frame(). You must use index, name/id, or WebElement.

After switching to an iFrame, how do you return to the main page?

A driver.switchTo().parentFrame()

B driver.quit()

C driver.switchTo().defaultContent()

D driver.switchTo().window()

driver.switchTo().defaultContent() returns to the main page from any iFrame.

What exception is commonly thrown if you try to access an element inside an iFrame without switching?

A NoSuchElementException

B TimeoutException

C ElementNotVisibleException

D StaleElementReferenceException

NoSuchElementException occurs because Selenium cannot find elements inside the iFrame without switching.

If a page has multiple iFrames, how can you switch to the second iFrame?

A driver.switchTo().frame(2)

B driver.switchTo().frame(1)

C driver.switchTo().frame("second")

D driver.switchTo().frame(0)

Frames are zero-indexed, so the second iFrame is at index 1.
