Selenium Docker Example

This project demonstrates running a Selenium test in a Docker container using Python and Chrome in headless mode. The test script opens Google, prints the page title, and saves a screenshot.

Project Structure

• test.py: Selenium test script.
• Dockerfile: Builds the Docker image with Chrome, ChromeDriver, and Python dependencies.
• requirements.txt: Python dependencies.
• .vscode/tasks.json: VS Code tasks for building and running the Docker container.
• .env: Environment variables for the container.
• /screenshots: Directory for storing screenshots (created automatically).

Prerequisites

• Docker installed
• Visual Studio Code (optional, for integrated tasks)

Usage

Build the Docker Image

docker build --pull --no-cache -t selenium-app .

Prepare Screenshots Folder

mkdir -p ./screenshots && chmod 777 ./screenshots

Run the Selenium Test

docker run --rm -v $(pwd)/screenshots:/screenshots --env-file .env selenium-app

Alternatively, use VS Code tasks:

• Docker Build: Builds the image.
• Prepare Screenshots Folder: Creates and sets permissions for the screenshots directory.
• Docker Run: Runs the test and saves the screenshot to ./screenshots/google.png.

Output

• The script prints the page title to the console.
• Screenshot is saved to ./screenshots/google.png.

Customization

• Modify test.py to change the test logic or target URL.
• Add environment variables to .env as needed.
