Integration Tests

A set of integration tests validate the released Aether Blueprints. The tests are managed by Jenkins, and can be monitored using the following Dashboard. Log files generated by recent runs are available on that site.

Source code for the integration tests can be found in the aether-jenkins repo on GitHub, where each file in the repo corresponds to a Groovy script that implements a Jenkins pipeline for one of the blueprints.

The pipelines are executed daily, with each pipeline parameterized to run in multiple jobs. The ${AgentLabel} parameter selects the Ubuntu release being tested (currently 22.04 and 24.04), with all jobs running in AWS VMs (currently resourced as M7iFlex2xlarge). Pipelines that exercise two-server tests—currently ueransim.groovy, upf.groovy, srsran.groovy, and gnbsim.groovy—invoke the AWS CLI to create the second VM.

All VMs created by Jenkins run images prepared using Packer, with the current specification templates available in the aether-packer repo on GitHub.

Finally, note that the integration tests run a variety of simulated 5G workloads, including gNBsim, UERANSIM, OAI 5G RAN (in simulation mode), and srsRAN (in simulation mode). Of these, gNBsim provides the most rigorous testing of the Core's control plane, and serves as Aether's primary validation of that functionality. More information about gNBsim can be found in the Emulated RAN section of this Guide.
