Build

Find an Alpine-base image on Dockerhub with a Java preinstalled.

Please do not install unnecessary dependencies!

Build container, make sure there are no errors during build.

Manual tests

1. Run the checker framework linter on a sample java project using checker framework installed on your computer

2. Perform the same analysis using your container

   docker run -v /local_folder:/container_folder -it linterhub/your_favorite_engine engine_command
   

   Make sure that outputs are equal.

Automated tests

Introduce a simple test as described above using Automated Test: https://docs.docker.com/docker-cloud/builds/automated-testing/#set-up-automated-test-files (ensure that expected analysis results are equal to the actual results).
