Setting Up Parallel Testing with Python, Cucumber, and Docker Compose

In this guide, we will walk you through the steps to set up parallel testing for your Python-based test suite using Cucumber as the test framework and Docker Compose for managing a Selenium Grid. Parallel testing allows you to distribute and run tests concurrently, improving test execution speed.

Prerequisites

  • Python installed on your system.
  • Docker and Docker Compose installed.
Pytest Selenium

Steps

1. Set Up Selenium Grid with Docker Compose

Create a docker-compose.yml file to define your Selenium Grid configuration with multiple nodes (e.g., Chrome, Firefox). Here’s a sample docker-compose.yml:

version: '3'
services:
  chrome:
    image: selenium/node-chrome:4.13.0-20231004
    # Configuration for Chrome node

  firefox:
    image: selenium/node-firefox:4.13.0-20231004
    # Configuration for Firefox node

  selenium-hub:
    image: selenium/hub:4.13.0-20231004
    # Configuration for Selenium Hub
Copy code
docker-compose up -d

2. Install Required Libraries

Install the necessary Python libraries for your project using pip. For example, you may need pytest, pytest-bdd, and selenium.

3. Write Parallel Test Scenarios

Write your test scenarios using Cucumber and pytest-bdd. Organize your tests into separate feature files or scenarios that you want to run in parallel.

4. Configure Parallel Test Execution

For pytest with pytest-xdist: Install the pytest-xdist plugin using pip:

5. Create a pytest configuration file (e.g., pytest.ini) with the following content to specify parallelization options:

[pytest]
addopts = -n auto

6. Execute Parrallel tests
