What is an element locator in Selenium?

An element locator is a way to find and select elements on a web page, like buttons or text fields, so you can interact with them in your tests.

Why do we use a page class in Selenium tests?

A page class groups all element locators and actions for one web page in one place. It makes tests easier to read and maintain, like having a map for that page.

Name four common locator strategies in Selenium.

Common locator strategies are: ID, Name, CSS Selector, and XPath. Each helps find elements differently, like using an address or a description.

What is the best practice for choosing locators in a page class?

Choose locators that are unique, stable, and simple. For example, prefer ID over XPath because IDs are usually unique and less likely to change.

How does using a page class improve test maintenance?

If a page changes, you only update locators in one place—the page class—instead of many test files. This saves time and reduces errors.

Which locator is usually the most reliable to use in Selenium?

A Class Name

B XPath

C ID

D Tag Name

ID is usually unique and stable, making it the most reliable locator.

What is the main purpose of a page class in Selenium tests?

A To group locators and actions for a web page

B To run tests faster

C To store test data

D To generate reports

A page class organizes locators and actions for one page, improving test clarity and maintenance.

Which locator strategy uses a path-like syntax to find elements?

A CSS Selector

B XPath

C Name

D ID

XPath uses a path syntax to navigate the HTML structure.

If a locator changes on the web page, where should you update it?

A In the test runner

B In every test file

C In the browser settings

D In the page class

Updating locators in the page class keeps tests consistent and easier to maintain.

Which of these is NOT a good locator choice?

A Randomly generated class name

B Stable CSS Selector

C Name attribute

D Unique ID

Random class names can change often, making tests fragile.
