End to end tests with Selenium Grid and Python

I’ll show you how to set up a comprehensive testing environment quickly and effortlessly.

We’ll be using Selenium WebDriver within a Selenium Grid, run locally via a Docker Compose configuration, and writing our tests in Python.

For reporting, we’ll use Allure.

And the best part? You can set everything up with just one command.

You’ll need:

• A functioning docker-compose setup
• Python 3 (we’ll install all necessary pip packages)

First, download the template:

git pull https://github.com/andgineer/e2e-tests.git

Navigate to the e2e-tests folder and run:

docker-compose up -d

Now, a Selenium Grid is operational, supporting Chrome and Firefox browsers for testing, console is available at http://localhost:4040.

It automatically generates reports from the data inside the allure-results folder.

Resulting Allure report is published at http://localhost:4040.

To run tests from tests/ and view the report, execute:

. ./activate.sh
./scripts/test.sh

Our tests include a --host parameter to specify the URL of the web application being tested. Implementation details see in pytest hook pytest_addoption of conftest.py.

For instance, to test https://google.com, you would run:

scripts/test.sh --host=https://google.com

This test will fail, as the word “Python” is not present on the Google main page.
