[Python] Warning came out when I raised from Selenium 3 to 4 [Web Driver]

Introduction

In a survey to write Previously posted Selenium article, I raised Selenium on my private PC from 3 to 4, but along with that, a large amount of Selenium 3 logs that were regularly executed by cron Warning now appears.

Since it is a Warning, the code itself ends normally, but I do not want the log to be unnecessarily long, so I analyzed the source code of Selenium 4 and corrected my code and succeeded in erasing all Warnings, so I will note here I will leave.

DeprecationWarning: executable_path has been deprecated, please pass in a Service object In Selenium3, if the browser driver is not in the PATH, the driver was started as follows.

from selenium import webdriver

driver = webdriver.Firefox(executable_path="/usr/local/bin/geckodriver")
driver.get('https://www.google.com/')

However, if you want to do the same with Selenium 4, you need to pass the executable_path to the Service object and then the Service object as shown below, instead of passing the executable_path directly when starting the driver.

from selenium import webdriver
from selenium.webdriver.firefox import service as fs

firefox_servie = fs.Service(executable_path="/usr/local/bin/geckodriver")
driver = webdriver.Firefox(service=firefox_servie)
driver.get('https://www.google.com/')

DeprecationWarning: service_log_path has been deprecated, please pass in a Service object When specifying the log output destination, the specification is to pass service_log_path to the Service object as well as executable_path. However, please be aware of the following two points.

** ① The name of the keyword will be log_path instead of service_log_path (2) It is necessary to pass executable_path to the Service object even if the browser driver is in the PATH. ** **

So in this case, the 4th line above is as follows.

firefox_servie = fs.Service(executable_path="/usr/local/bin/geckodriver", log_path='/my/log/path')

UserWarning: find_element_by_* commands are deprecated. Please use find_element() instead As you can see in the message, the function named find_element_by_ * is now deprecated, and the by_ * part is now specified by the keyword variable by offind_element ().

For example, suppose you have the following code for Selenium3: (It is assumed that the driver executable file is in the PATH)

from selenium import webdriver

driver = webdriver.Firefox()
driver.get('https://www.google.com/')
element = driver.find_element_by_xpath("//input[@type='text']")
element.send_keys('Qiita')
element.submit()

If this is made into the Selenium 4 specification, it will be as follows.

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

driver = webdriver.Firefox()
driver.get('https://www.google.com/')
element = driver.find_element(by=By.XPATH, value="//input[@type='text']")
element.send_keys('Qiita')
element.submit()

Summary

Rewriting find_element is quite troublesome, so if you have a lot of test code, it seems to be difficult unless you automate it as if you were writing a script.
