Small Sinatra application that returns information about cats available in the shop.

The application is a combination of plain text and JSON endpoints. Currently available endpoints

• / - hello page
• /cats/info - Read count of cats in database and presents info in readable text

Our company developed and released MVP of this application. We envision a great potential for the app and would like to keep building it in a fast and reliable way.

In order to achieve stable and productive development, we rely on automated tests. However, not all changes can be tested automatically so we would like to have a way to test merged code manually before it is pushed to production.

Help us build an automated pipeline for any pull requests that:

• Run automated tests on merged code with pull request target
• Deploy code to temporary server for manual testing
• Add comment to the pull request with link to the server
• Destroy server after pull request is closed

As you work on your solution you will inevitably have questions - please send all inquiries via slack. We are happy to assist and help

You are free to use any tool, infrastructure, technology you would like. However, it would be nice to see how you can use AWS to solve the task.

We would like to see a solution that has following traits:

• Automation - who likes to perform manual steps?
• Configuration - how can we adopt a similar solution for other products/flows/technologies?
• Code - infrastructure/provision/pipelines as a code works the best to: be readable for all engineers, maintain a truth and avoid any hidden manual configurations.
