A major advantage of certificate-based authentication compared to other STS authentication methods, like OpenID Connect or LDAP/AD, is that client authentication works without any additional/external component that must be constantly available. Therefore, certificate-based authentication may provide better availability / lower operational complexity.

This test artifact mechanism makes use of the concept of [component capabilities](https://docs.gradle.org/current/userguide/component_capabilities.html)
similar to how the gradle build-in `java-test-fixtures` plugin works.
