page with (user id, password and login) controls.
OR
We can also use
online page like Facebook login page.
Step 2
Install
python. If already you installed then ok

Implementation:
I will show you how you will
automate both type page like online (Facebook) and local html from.
First of all I will show you how we
can automate local page.
HTML Code For Local Page
<!DOCTYPE html>
<html lang = "en">
<head>
<meta charset = "UTF-8">
<meta name = "viewport" content="width=device-width, initial-scale=1.0">

<input id = "password" type="password" class="form-control" aria-describedby = "helpId" placeholder="Enter Password">
<small id = "helpId" class = "form-text text-muted">Please fill password box. </small>
</div>
<div class = "form-group">
<button id = "login" type="submit" class="btn btn-success"> Login </button>

<script>
var button = document.getElementById("login");
button.onclick = function(){
alert("Login has been done successfully")
}
</script>
</body>
</html>
Output
Local Login Form
Selenium Python Code
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
import time
def install_chrome():
chrome = (ChromeDriverManager().install())
dr = webdriver.Chrome(chrome)
return dr
def open_page(url):
dr = webdriver.Chrome()
dr.get(url)
return dr;
def get_element_by_Id(dr, id):
return dr.find_element_by_id(id)
driver = install_chrome()
driver = open_page('file:///C:/Users/Nouman%20Shoukat/Desktop/Py/selenium/index.html')
enrolment = get_element_by_Id(driver,'enrolment')
password = get_element_by_Id(driver,'password')
login = get_element_by_Id(driver,'login')
enrolment.send_keys("1234")
password.send_keys("459")
login.click()

| Local Login Form Automation |
in above python code you see three
method
install_chrome()
when this
function is called then a chrome is installed and return a object of web driver
chrome.
open_page(url)
when this
function is called then provided url page loaded and return a object of web
driver.
get_element_by_id(driver, id)
this
method used to access web page control by id for instance text box, button and etc.
this method
takes to arguments driver which is object of web driver while id is string
object while hold html tag ids.
Send_keys(str)
This method use
when we want to send text to web page. This method is access by object of
select tag or control from html tag.
Click()
This method use
when we want to click on html element. For this purpose we firstly access html
element for example we access a button element or anchor element then we
perform click action.
switch_to.alert
This is used to
access popup alert dialog box. We can accept or dismiss alert box.
To accept alert
box we use,
Object_name.accept()
for example alert,accept()
To dismiss alert
box we use,
Object_name.dismiss()
for example alert.dismiss()
Alert.text
This
is use to see prompt message in terminal.
Facebook Login Process
Simple set Facebook login page path
like this
driver = open_page(FACEBOOK_LOGIN_PAGE_PATH)
OR
Driver.get(FACEBOOK_LOGIN_PAGE_PATH)
And open inspect view of Facebook
login page and find text box ids and login buttion id
#Facebook login from control ids
email_and_phone_no_ID = 'email'
password_ID ='pass'
login_button_ID = 'u_0_d_Ks'
# Access Facebook login form controll eg email/Phone No text box, password text box and login button
email_text = get_element_by_Id(email_and_phone_no_ID)
password_textbox = get_element_by_Id(password_ID)
login_button = get_element_by_Id(login_button_ID)
#Asign your email or phone no and password
email_text.send_keys("YOUR_EMAIL/PHONE_NO")
password_textbox.send_keys("YOUR_PASSWORD")
#click login button
login_button.click()
