Utility classes in Selenium Java - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is a utility class in Selenium Java?

A utility class is a helper class that contains reusable methods to perform common tasks like waiting for elements, taking screenshots, or reading data. It helps avoid repeating code.

Why should utility classes have static methods?

Static methods allow calling utility functions without creating an object. This makes it easy to reuse methods anywhere in the test code.

Give an example of a common method in a Selenium utility class.

A method to wait for an element to be visible, like: <br>public static void waitForVisibility(WebDriver driver, WebElement element, int timeoutSeconds) {<br> new WebDriverWait(driver, Duration.ofSeconds(timeoutSeconds))<br> .until(ExpectedConditions.visibilityOf(element));<br>}

How do utility classes improve test maintenance?

By centralizing common code, utility classes make it easier to update logic in one place instead of many test files, reducing errors and saving time.

beginner

What is a best practice when naming utility classes?

Use clear, descriptive names like 'WaitUtils' or 'ScreenshotHelper' to indicate the purpose of the class and improve code readability.

What is the main benefit of using utility classes in Selenium tests?

A To reuse common code and avoid duplication

B To make tests run faster

C To create more test cases

D To store test data

Utility classes help reuse common code like waits or screenshots, reducing duplication and improving maintainability.

Which keyword is commonly used for methods in utility classes to avoid creating objects?

A static

B abstract

C private

D final

Static methods can be called without creating an instance of the class, making them ideal for utility methods.

Which of the following is NOT a typical utility class method in Selenium?

A Taking screenshots

B Launching the browser

C Waiting for element visibility

D Reading test data from files

Launching the browser is usually handled by setup code, not utility classes focused on reusable helper methods.

What should you do if you need to change the way you wait for elements in all tests?

A Ignore the change

B Update each test individually

C Change the wait method in the utility class

D Write new tests

Changing the wait method in the utility class updates all tests that use it, saving time and avoiding errors.

Which naming style is best for a utility class that handles waits?

A Test1

B MyClass

C Helper

D WaitUtils

Clear and descriptive names like 'WaitUtils' help understand the class purpose quickly.

Explain what a utility class is and why it is useful in Selenium Java testing.

Think about helper methods you use often in tests.

Describe how static methods in utility classes help simplify test code.

Consider how you call methods from utility classes.
