Automated Browser Testing with Edge and Selenium in Python

Cross-browser testing is mandatory in the software industry. We all know that there are many browsers like Firefox, Chrome, Edge, Opera etc., are available. Rather than writing separate code to each and every browser, it is always a decent approach to go towards automated testing. Let us see how to do that using Selenium for Edge browser in Python. Here Edge WebDriver is used in order to run our Selenium automation test scripts over the Edge browser.

Requirements

In order to perform Browser Automation using Edge And Selenium In Python, we need to carry out the following steps:

• Edge browser: Microsoft Edge browser can be downloaded from https://www.microsoft.com/en-us/edge. If already installed, we can get the existing version of edge by using edge://version/
• Selenium framework: Selenium is a powerful tool for controlling a web browser through the program. It is functional for all browsers, works on all major OS. It can be installed using the below command:

pip install selenium

• Edge WebDriver: Selenium Edge Webdriver can be downloaded from this URL. Automatically testing will be getting done in Edge browser with this driver. Download the edge webdriver according to the operating system and unzip the file and get msedgedriver.exe .
• Selenium tools for Microsoft Edge: This module has the required features for automated browser testing, it can be installed using the below command:

pip install msedge-selenium-tools selenium==3.141

Below is a program to execute a simple automated browser testing script:

# import required modules
from selenium import webdriver


# Driver Code
if __name__ == '__main__':

    # create object
    edgeBrowser = webdriver.Edge(r"msedgedriver.exe")

    # open browser and navigate to lambdatest Login Page
    edgeBrowser.get('https://www.lambdatest.com')

Output:

On executing the script, we can see, edge browser has opened Facebook page as shown in the image. You can open any valid web page and automatically it will open the mentioned web page in edge browser.

Step for Automation of Browser Testing with Edge and Selenium

1. Platform Selection

Choose the appropriate testing platforms. You can choose a local grid or a cloud grid like LambdaTest for scalability and reliability. It is an AI-powered test orchestration and execution platform that allows you to perform automated browser testing with Selenium, Python across different Edge browser versions. With LambdaTest, you can:

• Perform automated testing: Run automated tests with Python and popular Python testing frameworks like pytest, Robot, and more across 3000+ real environments.
• Perform visual regression testing: Automate your visual tests with an AI-powered SmartUI platform.
• View test reports: Get extension test execution logs of your Selenium Python tests for hassle-free debugging and testing on the go.

2. Browser Compatibility

• Test on multiple Edge versions or other desired browsers using LambdaTest extensive browser farm.
• Ensure cross-browser compatibility by identifying any layout or functionality issues.

3. Automated Actions:

• Maximize Window: Use the maximize_window() command within your Selenium script to optimize visual space.
• Open webpage: Leverage the get() method in Selenium to navigate to Facebook Page.

4. Data Parameterization

• Instead of hardcoding "gfg@lambdatest.com", utilize parameterization in your script to input different email addresses during testing.
• This allows testing valid and invalid email formats, enhancing test coverage.

5. Dynamic Element Identification

• Locate the "useremail" button using reliable identification methods like XPath or CSS selectors.
• Avoid fragile techniques like text-based matching to ensure script robustness across potential Ul changes.

6. Submit Action and Verification

• Use the click() method in Selenium to activate the button and trigger form submission.
• Verify successful and you have successfully Login to the LambdaTest page.

7. Advanced Features

• Visual testing: Capture screenshots before and after the submission to ensure visual consistency across browsers.
• Network analysis: Monitor network traffic during registration to entity potential performance bottlenecks.

Implementation

# Import required module
from selenium.webdriver.opera.options import Options
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support.wait import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.common.exceptions import TimeoutException
from selenium import webdriver
from time import sleep


# Driver Code
if __name__ == '__main__':
    
    # Instantiate the webdriver with the executable location of MS Edge
    # Provide the full location of the path to recognise correctly
    edgeBrowser = webdriver.Edge(r"msedgedriver.exe")
    
    # This is the step for maximizing browser window
    edgeBrowser.maximize_window()
    
    # Browser will get navigated to the given URL
    edgeBrowser.get('https://www.lambdatest.com')
    try:
        # We need to insert Email in order to proceed further. 
        # So it is given by using 'useremail'
        sampleElement = WebDriverWait(browser, 10).until(
            EC.presence_of_element_located((By.ID, 'useremail')))
        
        # We can give a valid email address and since 
        # this page carries the email id alone, it just 
        # appends the email id at the end
        sampleElement.send_keys("gfg@lambdatest.com")
        
        # A click is happening to move to next page
        sampleElement.click()
        
        # A Submit button is searched to click and start 
        # free testing. Actually "testing_form" is the id 
        # of the form, which needs to get tested
        sampleElement2 = WebDriverWait(browser, 10).until(
            EC.element_to_be_clickable((By.CSS_SELECTOR, 
                                        "#testing_form > div")))
        
        # Starting free testing on LambdaTest
        sampleElement2.click()
        
        # Just to show the set of actions happening, we can 
        # give sleep, you can change the values as per requirement
        sleep(20)
    except TimeoutException:
        print("Trying to find the given element but unfortunately no element is found")
    sleep(20)
    # Once all operations over, we can close browser too
    # edgeBrowser.close()

Output

Automated browser testing is very convenient and as separate drivers are available for each browser, we can do the testing easily and no manual work is needed. Even automated testing is faster and can test multiple test pages very quickly and provide successful test results.
