When multiple developers are working on e2e testing, it helps to be able to identify which infrastructure belongs to which Nomad SHA and which developer. This adds tags to the EC2 instances.
End to End Tests
This package contains integration tests.
The terraform folder has provisioning code to spin up a Nomad cluster on AWS. The tests work with the NOMAD_ADDR environment variable which can be set either to a local dev Nomad agent or a Nomad client on AWS.
Local Development
The workflow when developing end to end tests locally is to run the provisioning step described below once, and then run the tests as described below.
When making local changes, use ./bin/update $(which nomad) /usr/local/bin/nomad and ./bin/run sudo systemctl restart nomad to destructively modify the provisioned cluster.
Provisioning
You'll need AWS credentials (AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY) to create the Nomad cluster. See the README for details. The number of servers and clients is configurable, as is the configuration file for each client and server.
Running
After completing the provisioning step above, you should see CLI output showing the IP addresses of Nomad client machines. To run the tests, set the NOMAD_ADDR variable to http://[client IP]:4646/
$ NOMAD_ADDR=<> NOMAD_E2E=1 go test -v
