Clearing input fields in Selenium Python - Test Execution Trace

Test Overview

This test opens a web page with a text input field, enters some text, then clears the input field. It verifies that the input field is empty after clearing.

Test Code - Selenium

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 unittest

class TestClearInputField(unittest.TestCase):
    def setUp(self):
        options = Options()
        options.add_argument('--headless')
        self.driver = webdriver.Chrome(service=Service(), options=options)
        self.driver.get('https://example.com/input')

    def test_clear_input_field(self):
        driver = self.driver
        input_field = driver.find_element(By.ID, 'username')
        input_field.send_keys('testuser')
        input_field.clear()
        self.assertEqual(input_field.get_attribute('value'), '')

    def tearDown(self):
        self.driver.quit()

if __name__ == '__main__':
    unittest.main()

Execution Trace - 7 Steps

Step	Action	System State	Assertion	Result
1	Test starts and Chrome browser opens in headless mode	Browser is ready but no page loaded yet	-	PASS
2	Browser navigates to 'https://example.com/input'	Page with input field having id 'username' is loaded	-	PASS
3	Find input field by ID 'username'	Input field element is located	-	PASS
4	Send keys 'testuser' to input field	Input field contains text 'testuser'	-	PASS
5	Clear the input field using clear() method	Input field is empty	-	PASS
6	Assert that input field value is empty string	Input field value is ''	input_field.get_attribute('value') == ''	PASS
7	Close the browser and end test	Browser closed	-	PASS

Failure Scenario

Failing Condition: Input field is not found or clear() does not empty the field

Execution Trace Quiz - 3 Questions

What does the clear() method do in this test?

A It submits the form

B It clicks the input field

C It empties the text inside the input field

D It refreshes the page

Key Result

Always verify that the input field is actually cleared by checking its 'value' attribute after calling clear(). This ensures the field is empty before further actions.
