Working module of python selenium Architecture
Selenium Python uses the Selenium Client Library to convert Python commands into W3C WebDriver HTTP requests. These requests are sent to the browser-specific driver (e.g., chromedriver,edgedriver,etc), which acts as an HTTP server. The browser driver converts these commands into native browser instructions and performs them on the real browser like chrome. The driver then returns JSON responses back to Selenium, which Python interprets and gives to the script.
Workflow representation
What is virtual Environment:
A virtual environment is an isolated workspace where you can install python packages separately for each project.
This avoids version conflicts with interfering in common project structure
How to create Virtual environment
python -m venv myenv
A new folder myenv will be created
In myenv we have Activate scipts which runs and switch to new environment
Activate virtual environment
myenv\Scripts\activate
On Activating new virtual environment is created.
Virtual environment will be created. Then run the requirements.txt file, which contains project's required plugins or packages
My test execution requires pytest and selenium so I specified the following in requirement.txt
In order to execute the requirement.txt run the below comments
Why Virtual Environments Are Significant
Example 1: Different Selenium Versions for Two Test Frameworks
Scenario
We maintain:
Old Framework – uses Selenium 4.8
New Framework – uses Selenium 4.25
In global Python:
You can’t install both versions → conflict.
Solution:
Old framework
Activate:
pip install selenium==4.8
