Find element by name in Selenium Python - Cheat Sheet & Quick Revision

Recall & Review

beginner

What does the 'find_element(By.NAME, "name")' method do in Selenium?

It locates the first web element on the page that has the specified 'name' attribute.

beginner

How do you find an input field with the name 'username' using Selenium in Python?

Use: driver.find_element(By.NAME, "username") where 'driver' is your WebDriver instance.

intermediate

Why is using 'name' attribute a good locator strategy?

Because 'name' attributes are often unique for form elements and stable, making tests reliable and easy to maintain.

intermediate

What happens if 'find_element(By.NAME, "name")' does not find any element?

It raises a 'NoSuchElementException', indicating the element with that name does not exist on the page.

beginner

Show a simple Selenium Python code snippet to find an element by name and enter text.

from selenium.webdriver.common.by import By

input_field = driver.find_element(By.NAME, "email")
input_field.send_keys("[e-mail]")

Which Selenium method is used to find an element by its 'name' attribute in Python?

A find_element(By.NAME, "value")

B find_element(By.ID, "value")

C find_element(By.CLASS_NAME, "value")

D find_element(By.TAG_NAME, "value")

To find an element by its 'name' attribute, use By.NAME with find_element.

What exception is raised if no element with the specified name is found?

A NoSuchElementException

B TimeoutException

C ElementNotVisibleException

D StaleElementReferenceException

NoSuchElementException is raised when the element cannot be found.

Why might 'name' be preferred over 'id' for locating elements?

A Name attributes are always unique

B Name attributes load faster

C Name attributes are often stable and meaningful for forms

D Name attributes are case insensitive

Name attributes are often stable and meaningful, especially for form inputs.

Which import is necessary to use 'By.NAME' in Selenium Python?

A from selenium.webdriver.support.ui import WebDriverWait

B from selenium.webdriver.common.keys import Keys

C from selenium.webdriver.chrome.service import Service

D from selenium.webdriver.common.by import By

By is imported from selenium.webdriver.common.by to specify locator types.

What is the correct way to enter text into an element found by name 'password'?

A driver.find_element(By.CLASS_NAME, "password").send_keys("mypassword")

B driver.find_element(By.NAME, "password").send_keys("mypassword")

C driver.find_element(By.ID, "password").send_keys("mypassword")

D driver.find_element(By.NAME, "password").click()

Use send_keys on the element found by name to enter text.

Explain how to find a web element by its 'name' attribute using Selenium in Python and handle the case when the element is not found.

Think about locating and error handling.

Describe why using the 'name' attribute as a locator can be beneficial in test automation.

Consider stability and clarity of locators.

Practice

1. What does the Selenium method find_element(By.NAME, "username") do?

easy

A. Finds the element with the class name "username".

B. Finds the first element with the name attribute equal to "username".

C. Finds the element with the id attribute "username".

D. Finds all elements with the name attribute equal to "username".

Solution

1. Step 1: Understand the method purpose

   The method find_element locates a single element matching the given locator.

2. Step 2: Analyze the locator type

   Using By.NAME targets elements by their name attribute, not id or class.

3. Final Answer:

   Finds the first element with the name attribute equal to "username". -> Option B

4. Quick Check:

   find_element(By.NAME, "username") = first element by name [OK]

Hint: Remember: find_element finds one element by attribute [OK]

Common Mistakes:

• Confusing find_element with find_elements (plural)
• Using id or class instead of name attribute
• Assuming it finds multiple elements

2. Which of the following is the correct syntax to find an element by its name attribute "email" in Selenium Python?

easy

A. driver.find_element_by_name("email")

B. driver.find_element(By.ID, "email")

C. driver.find_element(By.NAME, "email")

D. driver.find_element(By.CLASS_NAME, "email")

Solution

1. Step 1: Recall modern Selenium syntax

   Since Selenium 4, the correct way is to use find_element(By.NAME, "email").

2. Step 2: Check each option

   driver.find_element_by_name("email") is deprecated syntax, C and D use wrong locator types.

3. Final Answer:

   driver.find_element(By.NAME, "email") -> Option C

4. Quick Check:

   Use By.NAME with find_element [OK]

Hint: Use By.NAME, not old find_element_by_name [OK]

Common Mistakes:

• Using deprecated find_element_by_name method
• Mixing locator types like ID or CLASS_NAME
• Forgetting to import By from selenium.webdriver.common.by

3. Given the code snippet:

from selenium import webdriver
from selenium.webdriver.common.by import By

driver = webdriver.Chrome()
driver.get('http://example.com')
element = driver.find_element(By.NAME, 'search')
print(element.tag_name)

What will be printed if the page has an input field with name="search"?

medium

A. An error because find_element is incorrect

B. "div"

C. "search"

D. "input"

Solution

1. Step 1: Understand what find_element returns

   It returns the first matching WebElement with name="search".

2. Step 2: Check the tag_name property

   The tag_name of an input field is "input".

3. Final Answer:

   "input" -> Option D

4. Quick Check:

   Element with name 'search' is input tag [OK]

Hint: tag_name shows HTML tag of found element [OK]

Common Mistakes:

• Confusing attribute value with tag name
• Assuming find_element returns text content
• Thinking find_element syntax is wrong here

4. What is wrong with this code snippet?

element = driver.find_element(By.name, "password")

medium

A. By.name should be By.NAME (case sensitive).

B. The method find_element does not exist.

C. The locator should be By.ID instead of By.name.

D. The quotes around "password" are incorrect.

Solution

1. Step 1: Check the locator usage

   Locator constants in Selenium are uppercase, so it should be By.NAME, not By.name.

2. Step 2: Verify other parts

   Method name and quotes are correct; locator type is appropriate for name attribute.

3. Final Answer:

   By.name should be By.NAME (case sensitive). -> Option A

4. Quick Check:

   Locator constants are uppercase in Selenium [OK]

Hint: Locator constants like By.NAME are uppercase [OK]

Common Mistakes:

• Using lowercase locator constants
• Confusing locator types (name vs id)
• Assuming method name is wrong

5. You want to fill a form field with name "user_email" using Selenium Python. Which code snippet correctly finds the element and enters the email "[e-mail]"?

hard

A. element = driver.find_element(By.NAME, "user_email")
element.send_keys("[e-mail]")

B. element = driver.find_element(By.ID, "user_email")
element.send_keys("[e-mail]")

C. element = driver.find_element(By.CLASS_NAME, "user_email")
element.send_keys("[e-mail]")

D. element = driver.find_element(By.NAME, "user_email")
element.click()

Solution

1. Step 1: Locate element by name attribute

   Use find_element(By.NAME, "user_email") to find the input field by its name.

2. Step 2: Enter text into the field

   Use send_keys("[e-mail]") to type the email into the field.

3. Final Answer:

   element = driver.find_element(By.NAME, "user_email") element.send_keys("[e-mail]") -> Option A

4. Quick Check:

   Find by name + send_keys to input text [OK]

Hint: Use send_keys after find_element to type text [OK]

Common Mistakes:

• Using wrong locator type (ID or CLASS_NAME)
• Using click() instead of send_keys() to enter text
• Not locating element before sending keys
