WebDriver Download location

WebDriver supports the below four browser types :

Firefox
IE
Opera
Chrome

Also support the below two mobile systems :

Android
IPhone

Additionationly support :

HtmlUnitDriver

The WebDriver download link : http://www.seleniumhq.org/download

Selenium - Login with a pop up window

This window is not alert window

Sample code :

from selenium import webdriver
import time
import win32com.client

# Setup
# pip install pypiwin32
# pip install selenium

# Reference :
# Login Window : https://stackoverflow.com/questions/40671662/how-to-handle-windows-authentication-popup-in-selenium-using-pythonplus-java

driver_location = "C:\web_driver\chromedriver.exe"
DUT_location = "http://192.168.1.1"
username = "admin"
password = "22Ejdkhc"

driver = webdriver.Chrome(driver_location)
#driver.maximize_window()
driver.get(DUT_location)

shell = win32com.client.Dispatch("WScript.Shell")   
shell.Sendkeys(username)  
time.sleep(2)
shell.Sendkeys("{TAB}")
time.sleep(2)
shell.Sendkeys(password) 
time.sleep(2)
shell.Sendkeys("{ENTER}")
time.sleep(2)

# Logout and close the browser
#driver.quit()

Selenium - scroll_into_view

# #X_TABLE_BASE = "//app-root//app-logs//app-eventlog//data-table"
# com_drop = DropdownButtonComponent(WebData.web_conn._ctx)
# err_drop, dom_drop = com_drop.locate_self("XPath", table_xpath)
# com_drop._locator.scroll_into_view(dom_drop)

Selenium - take a screenshot

Reference : https://www.geeksforgeeks.org/screenshot-element-method-selenium-python/

from selenium import webdriver

driver_location = "C:\web_driver\chromedriver.exe"
DUT_location = "http://192.168.30.233"

driver = webdriver.Chrome(driver_location)
driver.get(DUT_location)

myElement = driver.find_element_by_xpath('//*[@id="loginForm"]/div/div/img')
myElement.screenshot("current.png")

Selenium wait - Explicit Waits

Official page : https://selenium-python.readthedocs.io/waits.html

Sample code :

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

driver = webdriver.Firefox()
driver.get("http://somedomain/url_that_delays_loading")
try:
    element = WebDriverWait(driver, 10).until(
        EC.presence_of_element_located((By.ID, "myDynamicElement"))
    )
finally:
    driver.quit()

Expected Conditions

There are some common conditions that are frequently of use when automating web browsers. Listed below are the names of each. Selenium Python binding provides some convenience methods so you don’t have to code an expected_condition class yourself or create your own utility package for them.

title_is
title_contains
presence_of_element_located
visibility_of_element_located
visibility_of
presence_of_all_elements_located
text_to_be_present_in_element
text_to_be_present_in_element_value
frame_to_be_available_and_switch_to_it
invisibility_of_element_located
element_to_be_clickable
staleness_of
element_to_be_selected
element_located_to_be_selected
element_selection_state_to_be
element_located_selection_state_to_be
alert_is_present

Selenium - Execute JavaScript function

Reference : https://dzone.com/articles/perform-actions-using-javascript-in-python-seleniu

Element :

<area shape="rect" coords="111,84,155,655" alt="Cell ID: 2.
Module: 1
Voltage: 30.00 V.
High Threshold: 0.00 V.
Low Threshold: 0.00 V.
High Delta: -30.00 V.
Low Delta: 30.00 V.
Memos: 0
Baseline (US): 
Cell Balancing: False" title="Cell ID: 2.
Module: 1

High Threshold: 0.00 V.
Low Threshold: 0.00 V.

Low Delta: 30.00 V.
Memos: 0
Baseline (US): 
Cell Balancing: False" href="javascript:ChartItemClientClick('Cell ID: 2.
Module: 1
Voltage: 30.00 V.
High Threshold: 0.00 V.
Low Threshold: 0.00 V.
High Delta: -30.00 V.
Low Delta: 30.00 V.
Memos: 0
Baseline (US): 
Cell Balancing: False', 'imctl00_MainContent_ucStringView_ucStringViewDetails_pnlVoltageChartsWrapper_i0_i0_radchartVoltage-0-094324da-79da-42d9-9915-6956ae4dbb4e');">

=> This element can't be clicked by Selenium function, and need to be executed with Javascript as below

driver = webdriver.Chrome("chromedriver.exe")
inputElement = driver.find_element_by_xpath(xpath)
driver.execute_script("arguments[0].click();", inputElement)

How to deal with certificates using Selenium?

Reference : https://stackoverflow.com/questions/24507078/how-to-deal-with-certificates-using-selenium

from selenium import webdriver


options = webdriver.ChromeOptions()
options.add_argument('ignore-certificate-errors')

driver = webdriver.Chrome("D:\PythonTest\selenium_drivers\chromedriver.exe",chrome_options=options)
driver.get('https://cacert.org/')

driver.close()

Selenium - Get the page loading time

Reference : https://www.edureka.co/community/52561/how-measure-page-load-time-of-website-using-selenium-python

from selenium import webdriver

hyperlink = "http://www.baidu.com"
driver = webdriver.Chrome("chromedriver.exe")
driver.get(hyperlink)
 
navigationStart = driver.execute_script("return window.performance.timing.navigationStart")
responseStart = driver.execute_script("return window.performance.timing.responseStart")
domComplete = driver.execute_script("return window.performance.timing.domComplete")

backendPerformance_calc = responseStart - navigationStart
frontendPerformance_calc = domComplete - responseStart
 
print("Back End: %s" % backendPerformance_calc)
print("Front End: %s" % frontendPerformance_calc)
 
driver.quit()

How to remove the detect string in chromedriver

Summary :
Some websites will detect the simulator string , the related should be removed to avoid the detection

How to do :
vim /path/to/chromedriver
After running the line above, you'll probably see a bunch of gibberish. Do the following:

Replace all instances of cdc_ with dog_ by typing :%s/cdc_/dog_/g.
dog_ is just an example. You can choose anything as long as it has the same amount of characters as the search string (e.g., cdc_), otherwise the chromedriver will fail.
To save the changes and quit, type :wq! and press return.
If you need to quit without saving changes, type :q! and press return.

Selenium - How to start on Firefox WebDriver

coding=utf-8

from selenium import webdriver
driver = webdriver.Firefox(executable_path="C:\Python34\selenium\webdriver\geckodriver.exe")
driver.get("http://www.baidu.com")

driver.find_element_by_id("kw").send_keys("Selenium2")
driver.find_element_by_id("su").click()
driver.quit()

XPATH - 解析絕對路徑

XPATH : /html/body/app-root/nav/app-header/div/div/div[3]/div/div[1]

=> app-header : <app-header>...</app-header>
=> div : <div> without </div>
=> div[3] : the third place of  the below examples :  
                 <div></div> : 1
                 <div></div> : 2
                 <div></div> : 3
                 <div></div> : 4
=> div : <div></div> => Thus this div can't be ignored
=> div[1] : the first place of the below examples : 
                 <div></div> : 1
                 <div></div> : 2

Selenium - 幾種定位

coding=utf-8

from selenium import webdriver
driver = webdriver.Firefox(executable_path="C:\Python34\selenium\webdriver\geckodriver.exe")
driver.get("http://www.baidu.com")

Find by "id"

#driver.find_element_by_id("kw").send_keys("Selenium2")
#driver.find_element_by_id("su").click()

Find by "class name"

#driver.find_element_by_class_name("s_ipt").send_keys("Selenium2")
#driver.find_element_by_class_name("s_btn").click() #檢測元素找到是 "bg s_btn" , 不過s_btn才不會報錯 , 有partial find?

Find by "name" and "link_text"

#driver.find_element_by_name("wd").send_keys("Selenium2") # Find by "name"
#driver.find_element_by_link_text("百度一下").click() # Find by "link_text" => 報錯

Find by "xpath"

driver.find_element_by_xpath('//[@id="kw"]').send_keys("Selenium2")
driver.find_element_by_xpath('//[@id="su"]').click()

#driver.quit() # 關掉Firefox並離開
