Web Automation Testing using Selenium and Python
=================================================
First you need to check the python is already installed in the system.

In order to check this just type the below command

$ python or $ python3

It will result the as given below

Python 3.7.5

This is showing the installed version of python in the system.

Next we need to check the selienium is available in the python environment.
to check this follow below command.

$ python3
>>> import selenium
>>> help (selenium)

or 

$ python3 -c "import selenium; print(selenium.__version__)"

If you are getting the error, then we can say that we need to install the selenium.
Other wise we can understand that, it already added to to the python

Then add webdriver for the automated testing. We can use the diffrent browser webdriver like
driver for chrome, firefox, Edge, safari

you can download the chrome driver from the below URL
https://sites.google.com/a/chromium.org/chromedriver/downloads

Once downloaded, Then follow below commands. The driver class will connect you to browser instant nad key calss emulate the stroke of keyboard.

from selenium import webdriver
from selenium.webdriver.common.keys import Keys


Here we are assuming the dirver file is in the same directoy of python file. In this python file we are saving the automation code. 

driver = webdriver.Chrome('./chromedriver')

if you getting the “chromedriver” cannot be opened error, then just right click the driver file and then open. It will solve the issue.


Then we can use the get() method of driver.

driver.get("https://www.testsite.org")

This will load the testsite website

if you want to print the title of the website, then you can run below command.

print(driver.title)

This will output 

testsite website title

You can run multiple command on this session.

To close the current session, then you can use below command.

driver.close()


Also you can run the python file by adding all above code in the python file as follows.
add all command in the python file and save in the file name selenium_test.py

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Chrome('./chromedriver')
driver.get("https://www.python.org")
print(driver.title)
search_bar = driver.find_element_by_name("q")
search_bar.clear()
search_bar.send_keys("getting started with python")
search_bar.send_keys(Keys.RETURN)
print(driver.current_url)
driver.close()


Then save the same directoty of python file and execute the python file with below command.

$ python3 selenium_test.py

This execute all above code in a single strech.
