Selenium Python Tutorial 11 | Selenium python Logging | Log File

Moving on to the next tutorial in the Selenium Python Tutorials for Beginners. It deals with Python Automation Testing with Selenium WebDriver Python. This Selenium Python beginner tutorial explains Python Selenium logging with import logging library. You can log multiple messages using the Selenium Python logging at multiple levels (debug, info, warning, error and critical). First, view the Selenium Python Logging Tutorial. Then read on.

 After import logging in Python 3, you can use logging.basicConfig to configure logging e.g. to log only certain levels, specify a logging format or specify the log file. Here is the first Selenium Python logging example, which is in Logs.py file in the Selenium Python tutorial 11. The explanations are in the comments within the code (lines or phrases starting with #).

# Selenium WebDriver Python coding
# import Python logging library with the alias, L
import logging as L
# Configure logging to start with severity level, DEBUG.
L.basicConfig(level=L.DEBUG)
L.debug('Debug message')
L.info('Info message')
L.warning('Warning message')
L.error('Error message')
L.critical('Critical message')

This is my Python user defined function to log messages automatically. I put it in the Utilities.py file that I showed in the Selenium Python tutorial 10.

# Selenium WebDriver Python coding

import logging as L

def log(level, message, file):
    # Configure logging to start with the INFO level, the log file and the filemode as append to log file.

    L.basicConfig(level=L.INFO, filename=file, filemode="a",
                  format="%(asctime)-12s %(levelname)s %(message)s", # log entry format
                  datefmt="%d-%m-%Y %H:%M:%S") # date time format
    if level == "INFO": L.info(message)
    if level == "WARNING": L.warning(message)
    if level == "ERROR": L.error(message)
    if level == "CRITICAL": L.critical(message)

Here is my log function called in the Checkbox.py Selenium Python example that I showed in the Selenium Python tutorial 3. The Checkbox.py Selenium Python script answers a quiz automatically until each answer is "Correct." or it runs out of checkbox combinations.

# Selenium WebDriver Python coding
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait as W
from selenium.webdriver.support import expected_conditions as E
import CheckboxFunctions as C
# Import Utilities in order to call the log function.
import Utilities as U

exec_path = r"E:\Training\SeleniumPython\Downloads\geckodriver-v0.26.0-win32\geckodriver.exe"
URL = "https://inderpsingh.blogspot.com/2013/01/HTMLCSSQuiz1.html"
wait_time_out = 15
check_name_locator = "option"
# Specify the log file file path and file name with your computer's folder. Escape the backslashes.
# The following is an example only.
log_file = "E:\\Training\\SeleniumPython\\Logs\\LogCheckBoxQuiz.txt"
# Specify the log message for pass and fail.
pass_message = "Answered correctly - Question Number"
fail_message = "Answered incorrectly - Question Number"

driver = webdriver.Firefox(executable_path=exec_path)
wait = W(driver, wait_time_out)
driver.get(URL)
i = 0
while i<10:
    i += 1
    driver.execute_script("window.scrollBy(0,120)","")
    check_element_1 = wait.until(E.presence_of_element_located((By.NAME, check_name_locator + str(i) + "1")))
    check_element_2 = wait.until(E.presence_of_element_located((By.NAME, check_name_locator + str(i) + "2")))
    check_element_3 = wait.until(E.presence_of_element_located((By.NAME, check_name_locator + str(i) + "3")))
    check_element_1.click()
    check_element_2.click()
    check_element_3.click() # checkboxes 1, 2 & 3 are selected
    if C.answered(driver, i):
        # Python Selenium logging if the question is answered successfully
        U.log("INFO", pass_message + str(i), log_file)
        continue
    check_element_1.click() # checkboxes 2 & 3 are selected
    if C.answered(driver, i):
        # Python Selenium logging if the question is answered successfully
        U.log("INFO", pass_message + str(i), log_file)
        continue
    check_element_1.click()
    check_element_2.click() # checkboxes 1 & 3 are selected
    if C.answered(driver, i):
        # Python Selenium logging if the question is answered successfully
        U.log("INFO", pass_message + str(i), log_file)
        continue
    check_element_2.click()
    check_element_3.click() # checkboxes 1 & 2 are selected
    if C.answered(driver, i):
        # Python Selenium logging if the question is answered successfully
        U.log("INFO", pass_message + str(i), log_file)
        continue
    check_element_2.click() # only checkbox 1 is selected
    if C.answered(driver, i):
        # Python Selenium logging if the question is answered successfully
        U.log("INFO", pass_message + str(i), log_file)
        continue
    check_element_1.click()
    check_element_2.click() # only checkbox 2 is selected
    if C.answered(driver, i):
        # Python Selenium logging if the question is answered successfully
        U.log("INFO", pass_message + str(i), log_file)
        continue
    check_element_2.click()
    check_element_3.click()# only checkbox 3 is selected
    if C.answered(driver, i):
        # Python Selenium logging if the question is answered successfully
        U.log("INFO", pass_message + str(i), log_file)
        continue
    # Selenium Python logging if the question is still unanswered.
    U.log("ERROR", fail_message + str(i), log_file)

The above Selenium Python script calls the answered user defined function that I wrote in CheckboxFunctions.py file below.

from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait as W
from selenium.webdriver.support import expected_conditions as E
wait_time_out = 15
def answered(d, question_number):
    wait_variable = W(d, wait_time_out)
    answer_element = wait_variable.until(E.presence_of_element_located((By.NAME, "answer" + str(question_number))))
    if "Correct." in answer_element.get_attribute("value"):
        return True
    else:
        return False
