Question 1

In Selenium Grid 4, what is the role of the 'Hub'?

Accepted Answer

Acts as a central router that distributes test sessions to registered nodes

Answer

The Hub receives WebDriver requests from clients and routes each session to an available Node that matches the requested capabilities.

Question 2

Which XPath expression selects a button element that contains the text 'Submit'?

Accepted Answer

//button[contains(text(),'Submit')]

Answer

The XPath function contains(text(),'Submit') matches any button whose text node includes the string 'Submit'.

Question 3

What is the difference between `findElement()` and `findElements()` in WebDriver?

Accepted Answer

findElement() throws NoSuchElementException if not found; findElements() returns an empty list

Answer

findElement() throws NoSuchElementException when no match exists, while findElements() silently returns an empty List<WebElement>.

Question 4

Which Selenium 4 feature allows you to capture a screenshot of a specific WebElement rather than the full page?

Accepted Answer

element.getScreenshotAs(OutputType.FILE)

Answer

In Selenium 4, WebElement implements TakesScreenshot, so element.getScreenshotAs(OutputType.FILE) captures just that element's area.

Question 5

Which technique is used to wait for an AJAX call to complete before interacting with dynamically loaded elements?

Accepted Answer

Explicit wait with an appropriate ExpectedCondition

Answer

Explicit waits using WebDriverWait and ExpectedConditions poll until the AJAX result appears in the DOM, avoiding hard-coded sleeps.
