Overview

This repo shows a basic example of using Cypress and Docker Compose to create simple end-to-end tests for any web application. This example uses a Go application, but you can reuse the pattern in this repository for any web application that can run in Docker.

For more information, see the blog post, "Easy End-to-End Testing with Cypress."

Run the test app

The example application is called Sentimentalyzer, a very rudimentary text sentiment analyzer. To run it, enter the following commands:

docker build --tag sentimentalyzer .
docker run \
  --interactive \
  --tty \
  --env PORT=8123 \
  --publish 8123:8123 \
  sentimentalyzer

The app will be running on localhost:8123.

Run end-to-end tests

To execute the end-to-end tests for Sentimentalyzer, enter the following commands:

cd e2e
docker-compose up --abort-on-container-exit --exit-code-from cypress

When the command completes, you will see test output on the console and a video of the test run will appear in the folder e2e/cypress/integration/videos.
