Clair vs Testcontainers: What are the differences?

Developers describe Clair as "Open Source Vulnerability Analysis for your Containers". Clair is a container vulnerability analysis service by CoreOS. It provides the list of vulnerabilities that threaten each container and can sends notifications whenever new vulnerabilities that affect existing containers are released. On the other hand, Testcontainers is detailed as "A library that integrates Docker with testing libs - for databases, Selenium web browsers, or anything else that can run in a Docker container". It is a Java library that supports JUnit tests, providing lightweight, throwaway instances of common databases, Selenium web browsers, or anything else that can run in a Docker container.

Clair and Testcontainers belong to "Container Tools" category of the tech stack.

Some of the features offered by Clair are:

• api defines how users interact with Clair and exposes a documented HTTP API.
• worker extracts useful informations from layers and store everything in the database.
• updater periodically updates Clair's vulnerability database from known vulnerability sources.

On the other hand, Testcontainers provides the following key features:
