Know how to write Selenium test using Python

Selenium supports many languages, in which python is one.

We have discussed how we can write and run selenium tests using java.

In this post, we will see how to run selenium scripts using python

Prerequisite

Download and setup python

Chose an editor from list of python editor

Configure & run python on PyCharm [my preference]

Configure & run python on Visual studio code [Watch video]

Install selenium python package

Open cmd / terminal and type

pip install -U selenium

For Mac OS – pip3 install -U selenium

This will install selenium python package in to local drive or local project repo

Sample selenium python script

Open Pycharm editor and create a new python file with extension .py, let’s firstSelPython.py

from selenium import webdriver
import time

# driver = webdriver.Firefox(executable_path="C:\\Grid\\geckodriver.exe")
# driver = webdriver.Ie(executable_path="C:\\Grid\\IEdriverserver.exe")

driver = webdriver.Chrome("C:\\Grid\\chromedriver.exe")
driver.maximize_window()
driver.implicitly_wait(30)
driver.set_page_load_timeout(50)
driver.get("https://qavbox.github.io/demo")
assert "QAVBOX" in driver.title
driver.find_element_by_link_text("SignUp Form").click();
driver.save_screenshot("c:\\Grid\\test.png")
time.sleep(3)
driver.quit();

To run this code

Open terminal, navigate to project repo and type

python3 <Filename>.py

For windows – python <filename>.py

Explanation

from selenium import webdriver
Get all the webdriver implementation from selenium module, like we have import org.openqa.selenium.WebDriver; in java.

driver = webdriver.Chrome("<path of chrome driver>")
get the webdriver instance [as driver] and Invoke chrome browser, pass the chromedriver executable as parameter.

For Firefox
driver = webdriver.Firefox("<path of firefox driver")

Note –

Example –

For MacOS –

driver = webdriver.Chrome("/Users/SomeFolder/chromedriver")

For Windows OS

driver = webdriver.Chrome("C:\\SomeFolder\\chromedriver.exe")

To maximize browser window
driver.maximize_window()

Implicit wait in seconds
driver.implicitly_wait(30)

Wait for 50 sec before showing page time out error if page is not loaded
driver.set_page_load_timeout(50)

To load the url on browser
driver.get("https://qavbox.github.io/demo")

Check if the title contains text “QAVBOX”
assert "QAVBOX" in driver.title

Locating an element and perform action
driver.find_element_by_link_text("SignUp Form").click();

Other available locators are

To take screenshot, use save_screenshot() and specify the path to save the screenshot
driver.save_screenshot("c:\\Grid\\test.png")

Hard wait using native python method time.sleep()
time.sleep(3)

Stay tuned for more selenium tests using python!
