The examples provided by the project also serve as integration tests and therefore they should always work and be relatively up-to-date. The bundles in this folder showcase how the org.apache.sling.scripting.bundle.tracker.
All the test endpoints will be in the resource tree under the /content/bundled-scripts/ folder.
All the servlets registered by the Apache Sling Scripting Bundle Tracker will have their providers registered in the /apps/org.apache.sling.scripting.examplebundle.* and /apps/sling/scripting/examplebundle* folders.
The integration tests using these bundles can be found here and you can find instructions to start a running sling instance with the provided examples here.
