Selenium with Python Example

1. Introduction

This is an article about using selenium with python. Selenium is used for functional testing. It supports python scripting.

2. Selenium with Python

2.1 Prerequisites

Python 3.6.8 is required on windows or any operating system. Pycharm is needed for python programming. Selenium and eclipse need to be installed for test script execution.

2.2 Download

Python 3.6.8 can be downloaded from the website. Pycharm is available at this link. Eclipse can be downloaded from this link.

2.3 Setup

2.3.1 Python Setup

To install python, the download package or executable needs to be executed.

2.3.2 Selenium Setup

You can install Selenium using the command below:

Selenium Setup
pip3 install Selenium

2.4 IDE

2.4.1 Pycharm Setup

Pycharm package or installable needs to be executed to install Pycharm.

2.5 Launching IDE

2.5.1 Pycharm

Launch the Pycharm and start creating a pure python project named HelloWorld. The screen shows the project creation.

Pycharm Create project

The project settings are set in the next screen as shown below.

Pycharm Project Settings

Pycharm welcome screen comes up shows the progress as indicated below.

Pycharm Project View

You can create a and execute the python file by selecting the Run menu.

Pycharm Hello World

The output message “Hello World” is printed when the python file is Run.

Pycharm Python Execution

2.6 What is Python?

Python is a programming language used for developing software and web applications. It has Object-oriented programming constructs to create applications. Python is opensource. It is a scripting language that has an interpreter. Python helps in creating software applications quickly and debugging them.

2.7 What is Selenium?

Selenium is used for automation testing. It is used for creating automation tests from manual test cases. Selenium has support for Java, C#, Ruby, Perl, and Python. The test scripts can be executed with Selenium on Windows, Linux, and Mac OS. The test scripts can be executed on various browsers such as Chrome, Firefox, Edge, Safari, and others. Testing tools like TestNG and Junit can be integrated with Selenium test for test suite management and reports generation. Selenium has support for Maven, Jenkins, and Docker testing tools.

2.8 Why choose Python over Java in Selenium?

Python has better support for multiple programming paradigms. It has built-in testing frameworks like Pytest and Robot. Compared to java, python has better debugging and faster workflow. Python is a cross-platform language and can be used with other programming languages like C, C++, and Java. Selenium test scripts can be developed using PyDev in Eclipse and Selenium configured with Python. Selenium can be configured with python by installing selenium packages. Pycharm IDE can be used for Selenium Test scripts development and execution.

2.9 How to Install and Configure PyDev in Eclipse?

PyDev can be installed in Eclipse for creating Selenium test scripts. PyDev is installed by accessing the marketplace and searching in PyDev.

PyDev in Eclipse

PyDev can be installed by clicking on the install button. The screen shot below shows the next screen.

PyDev – Confirm

You can create a new project by clicking on create a new project from the menu as shown below:

PyDev Project

You can configure the interpreter for the PyDev project.

Python Intrepeter

You can create a new package after creating the PyDev Project from the menu as shown below:

PyDev Package

You can create a PyDev module by selecting the PyDev module from the menu:

PyDev Module

2.10 How to Create Test Scripts in Selenium with Python

To execute the test scripts we will use the flask application created in this article. Flask App is executed as shown below: Flask App

apples-MacBook-Air:flask bhagvan.kommadi$ source flaskenv/bin/activate
(flaskenv) apples-MacBook-Air:flask bhagvan.kommadi$ ls	customers.db	templates	flaskenv	history.txt
(flaskenv) apples-MacBook-Air:flask bhagvan.kommadi$ python3
 * Serving Flask app "Customer" (lazy loading)
 * Environment: production
   WARNING: This is a development server. Do not use it in a production deployment.
   Use a production WSGI server instead.
 * Debug mode: on
 * Running on (Press CTRL+C to quit)
 * Restarting with stat
 * Debugger is active!

The below test script is used in PyDev project for execution. Selenium Test Script

Created on Mar 30, 2021
@author: bhagvan.kommadi
from selenium import webdriver  
import time  
from selenium.webdriver.common.keys import Keys  
from import ChromeDriverManager
driver = webdriver.Chrome(ChromeDriverManager().install())
print("test case starting now")  
driver.find_element_by_xpath("//a[contains(text(),'Add Customer')][1]").click()  
driver.find_element_by_xpath("//input[@type='text'][@name='name'][1]").send_keys("Jack Hill")
driver.find_element_by_xpath("//input[@type='text'][@name='address'][1]").send_keys("345 Hill Drive, Sanjose 30489")
print("Customer creation")

Chrome driver is downloaded into the project from this link. Webdrivermanager is installed using the command below: Web Driver Manager

pip3 install webdriver-manager

The code is executed as shown below:

PyDev Script Execution

The output is shown in the next set of images below.

Output First Page

The next page is reached by the selenium by clicking on the link – Add Customer.

Output – Second page

The next page comes when script clicks on the submit button. The screen shot below shows the last page.

Output Last page
