@FindBy annotations in Selenium Java - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the purpose of the @FindBy annotation in Selenium?

The @FindBy annotation is used to locate web elements on a page in Selenium's Page Object Model. It helps to define how to find elements using locators like id, name, xpath, cssSelector, etc.

beginner

How do you use @FindBy to locate an element by its ID?

You use @FindBy(id = "elementId") before a WebElement field to tell Selenium to find the element with that ID.

intermediate

Can @FindBy use multiple locator strategies together? If yes, how?

Yes, by using @FindBys or @FindAll annotations to combine multiple @FindBy annotations for AND or OR conditions respectively.

beginner

What happens if Selenium cannot find an element defined with @FindBy during test execution?

Selenium throws a NoSuchElementException when it tries to interact with the element and cannot find it on the page.

beginner

Why is using @FindBy considered better than using driver.findElement() directly in tests?

Using @FindBy supports the Page Object Model, making tests cleaner, easier to maintain, and separating element locators from test logic.

Which of the following is a valid way to locate an element using @FindBy?

A @FindBy(className = "btn")

B @FindBy(text = "username")

C @FindBy(id = "username")

D @FindBy(tag = "input")

The correct locator attribute is 'id'. 'text' and 'tag' are not valid attributes for @FindBy. The correct attribute for class is 'className' (case sensitive).

What type of variable should be annotated with @FindBy?

A List<String>

B String

C int

D WebElement

@FindBy is used to locate WebElement or List<WebElement> variables.

Which annotation allows combining multiple @FindBy annotations with AND logic?

A @FindAll

B @FindBys

C @FindByMultiple

D @FindByGroup

@FindBys combines multiple @FindBy annotations with AND logic.

If you want to locate elements by CSS selector using @FindBy, which attribute do you use?

A cssSelector

B css

C style

D selector

The correct attribute is cssSelector.

What is the main advantage of using @FindBy in Page Object Model?

A It separates element locators from test logic

B It makes tests run faster

C It automatically waits for elements

D It replaces the need for assertions

@FindBy helps separate element locators from test logic, improving code organization and maintainability.

Explain how to use the @FindBy annotation to locate a button by its CSS class and why this is useful in test automation.

Think about how you tell Selenium where to find the element and how it helps keep tests clean.

Describe what happens when Selenium cannot find an element defined with @FindBy during test execution and how you might handle it.

Consider what Selenium does when it looks for an element that is missing and how to make tests more reliable.
