Summary

Unit tests are designed for specific module functionality.
Integration tests are designed for the whole system.
Continuous integration is an environment where tests are run every time a new code is pushed to the repository before the updated model is deployed.
A quick survey of continuous integration tools yields several options: CircleCI, Travis CI, Jenkins, and Buildkite.
