[Solved] Consider this Base Page method:public boolean checkElementVisible(By locator) { try { WebElement element = driver.findElement(locator);... } }What is a potential problem with this implementation? | Selenium Java

Selenium Java - Page Object Model

Consider this Base Page method:

public boolean checkElementVisible(By locator) {
  try {
    WebElement element = driver.findElement(locator);
    return element.isDisplayed();
  } catch (Exception e) {
    return false;
  }
}

What is a potential problem with this implementation?

Adriver.findElement returns a list, so this code will not compile

BThe method should throw exceptions instead of returning false

CUsing isDisplayed() is incorrect; should use isEnabled()

DCatching generic Exception may hide unexpected errors; better to catch NoSuchElementException

Step-by-Step Solution

Solution:

Step 1: Understand Exception Handling
Catching generic Exception can mask other issues beyond element absence.
Step 2: Identify Best Practice
It's better to catch specific exceptions like NoSuchElementException to handle element absence gracefully.
Step 3: Reasoning
This improves debugging and avoids hiding unrelated errors.
Final Answer:
Catching generic Exception may hide unexpected errors; better to catch NoSuchElementException -> Option D
