Typing text (send_keys) in Selenium Python

Introduction

Typing text into input fields is a common action in web testing to simulate user input.

Filling out a login form with username and password.

Entering search terms in a search box on a website.

Typing data into a form field during automated form submission tests.

Simulating user input to test validation messages.

Automating repetitive data entry tasks in web applications.

Syntax

Selenium Python

element.send_keys('text to type')

element is the web element you want to type into, found using locators.

send_keys simulates keyboard typing into that element.

Examples

Types 'Selenium testing' into the search box found by its ID.

Selenium Python

search_box = driver.find_element(By.ID, 'search')
search_box.send_keys('Selenium testing')

Types 'user123' into the username input field found by its name attribute.

Selenium Python

username_field = driver.find_element(By.NAME, 'username')
username_field.send_keys('user123')

Types 'mypassword' into the password field found by CSS selector.

Selenium Python

password_field = driver.find_element(By.CSS_SELECTOR, 'input[type="password"]')
password_field.send_keys('mypassword')

Sample Program

This script opens a login page, types a username and password into input fields, then checks if the text was entered correctly. It prints a success message if all is well.

Selenium Python

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.chrome.options import Options
import time

# Setup Chrome driver (adjust path as needed)
options = Options()
options.add_argument('--headless')  # Run in headless mode
service = Service()
driver = webdriver.Chrome(service=service, options=options)

try:
    driver.get('https://www.example.com/login')

    # Locate username and password fields
    username = driver.find_element(By.ID, 'username')
    password = driver.find_element(By.ID, 'password')

    # Type text into fields
    username.send_keys('testuser')
    password.send_keys('securepass')

    # Verify typed text (get attribute 'value')
    assert username.get_attribute('value') == 'testuser', 'Username input failed'
    assert password.get_attribute('value') == 'securepass', 'Password input failed'

    print('Test passed: Text typed correctly')
finally:
    driver.quit()

Important Notes

Always locate elements using reliable locators like ID or name for stability.

Use get_attribute('value') to verify the text typed into input fields.

Remember to close the browser with driver.quit() to free resources.

Summary

send_keys types text into web elements like input boxes.

Use it to simulate user typing in automated tests.

Verify typed text by checking the element's value attribute.

Practice

1. What does the send_keys method do in Selenium Python?

easy

A. It types text into input fields or other elements.

B. It clicks on buttons or links.

C. It retrieves the text from an element.

D. It waits for an element to be visible.

Solution

1. Step 1: Understand the purpose of send_keys

   The send_keys method simulates typing text into input fields or editable elements in Selenium.

2. Step 2: Differentiate from other actions

   Clicking, retrieving text, or waiting are done by other methods like click(), text property, or WebDriverWait.

3. Final Answer:

   It types text into input fields or other elements. -> Option A

4. Quick Check:

   send_keys = types text [OK]

Hint: send_keys means typing text into fields [OK]

Common Mistakes:

• Confusing send_keys with click()
• Thinking send_keys reads text
• Assuming send_keys waits for elements

2. Which of the following is the correct syntax to type the text "hello" into an input element stored in variable input_box?

easy

A. input_box.write("hello")

B. input_box.send_keys("hello")

C. input_box.enter("hello")

D. input_box.type("hello")

Solution

1. Step 1: Recall the method name for typing text

   In Selenium Python, the method to type text is send_keys().

2. Step 2: Check the syntax correctness

   The correct syntax is calling send_keys on the element with the text as a string argument.

3. Final Answer:

   input_box.send_keys("hello") -> Option B

4. Quick Check:

   Correct method is send_keys() [OK]

Hint: Use send_keys() to type text, not type() or enter() [OK]

Common Mistakes:

• Using non-existent methods like type() or enter()
• Forgetting parentheses after send_keys
• Passing non-string arguments

3. What will be the value of the input box after executing this code?

input_box = driver.find_element(By.ID, "username")
input_box.send_keys("user123")
print(input_box.get_attribute("value"))

medium

A. "" (empty string)

B. "input_box"

C. "user123"

D. Throws an error

Solution

1. Step 1: Understand send_keys effect on input value

   Calling send_keys("user123") types "user123" into the input box, setting its value attribute.

2. Step 2: Retrieve the value attribute

   get_attribute("value") returns the current text inside the input box, which is "user123".

3. Final Answer:

   "user123" -> Option C

4. Quick Check:

   send_keys sets value attribute = "user123" [OK]

Hint: send_keys sets input value; get_attribute('value') reads it [OK]

Common Mistakes:

• Expecting get_attribute to return element name
• Thinking send_keys clears input automatically
• Assuming print shows element object

4. You want to type "admin" into an input box but your test fails with an error. Which line fixes the error?

input_box = driver.find_element(By.ID, "user")
input_box.send_keys(admin)

medium

A. input_box.send_keys("admin")

B. input_box.send_keys('admin")

C. input_box.send_keys(admin)

D. input_box.send_keys()

Solution

1. Step 1: Identify the error cause

   The argument admin is not in quotes, so Python treats it as a variable, causing a NameError.

2. Step 2: Fix by passing a string literal

   Enclose "admin" in quotes to pass it as a string: send_keys("admin").

3. Final Answer:

   input_box.send_keys("admin") -> Option A

4. Quick Check:

   Text must be a string in quotes [OK]

Hint: Always put text in quotes inside send_keys() [OK]

Common Mistakes:

• Passing variable without quotes
• Leaving send_keys empty
• Using single quotes inconsistently (valid but watch syntax)

5. You want to type a password into a field but first clear any existing text. Which code snippet correctly does this?

hard

A. input_box.clear("mypassword")

B. input_box.send_keys("")
input_box.send_keys("mypassword")

C. input_box.send_keys("mypassword")
input_box.clear()

D. input_box.clear()
input_box.send_keys("mypassword")

Solution

1. Step 1: Clear existing text before typing

   Use clear() method to remove any existing text in the input box.

2. Step 2: Type the new password

   After clearing, call send_keys("mypassword") to type the password.

3. Final Answer:

   input_box.clear() input_box.send_keys("mypassword") -> Option D

4. Quick Check:

   Clear first, then send_keys [OK]

Hint: Clear input before typing new text with clear() [OK]

Common Mistakes:

• Typing before clearing causes leftover text
• Using clear() with arguments (invalid)
• Sending empty string to clear input
