Test class using page objects in Selenium Python - Cheat Sheet & Quick Revision

Recall & Review

What is a Page Object in Selenium testing?

A Page Object is a design pattern that creates an object to represent a web page. It contains locators and methods to interact with page elements, making tests easier to read and maintain.

Why use a Test Class with Page Objects?

A Test Class uses Page Objects to separate test logic from page details. This keeps tests clean, reusable, and easier to update when the web page changes.

In a Page Object, how should locators be defined?

Locators should be private or protected variables using clear and stable selectors like IDs or data attributes. This helps avoid brittle tests that break easily.

What is the role of assertions in a Test Class using Page Objects?

Assertions check if the web page behaves as expected after actions. They verify results like text presence or element visibility to confirm the test passes or fails.

How does using Page Objects improve test maintenance?

When page structure changes, only the Page Object needs updating. Tests using it stay the same, saving time and reducing errors.

What does a Page Object typically contain?

A Only test assertions

B Locators and methods to interact with page elements

C Database connection code

D User interface design

A Page Object holds locators and methods to interact with the web page elements.

Where should assertions be placed in Selenium tests using Page Objects?

A Inside the Test Class

B Inside the Page Object

C In the browser console

D In the web page HTML

Assertions belong in the Test Class to verify expected outcomes after using Page Object methods.

Which locator strategy is best for stable Page Objects?

A Using IDs or data attributes

B Using absolute XPaths

C Using random class names

D Using inline styles

IDs and data attributes are stable and less likely to change, making tests more reliable.

What is a key benefit of separating test logic from page details?

A Less readable tests

B Slower test execution

C More complex code

D Easier test maintenance

Separating logic makes tests easier to maintain and update.

In Selenium Python, which library is commonly used for assertions?

A matplotlib

B requests

C unittest

D pandas

The unittest library provides assertion methods for test verification.

Explain how a Test Class uses Page Objects to perform a login test.

Think about how the test interacts with the page through the object.

Describe the advantages of using the Page Object pattern in Selenium tests.

Consider how changes in the web page affect tests.
