README.md

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 Test Infrastructure on AWS

You'll need Terraform and AWS credentials (AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY) to setup AWS instances on which e2e tests will run. See the README for details. The number of servers and clients is configurable, as is the configuration file for each client and server.

Provisioning e2e Framework Nomad Cluster

You can use the Terraform output from the previous step to generate a provisioning configuration file for the e2e framework.

# from the ./e2e/terraform directory
terraform output provisioning | jq . > ../provisioning.json

By default the provisioning.json will not include the Nomad version that will be deployed to each node. You can pass the following flags to go test to set the version for all nodes:

  • -nomad.local_file=string: provision this specific local binary of Nomad. This is a path to a Nomad binary on your own host. Ex. -nomad.local_file=/home/me/nomad
  • -nomad.sha=string: provision this specific sha from S3. This is a Nomad binary identified by its full commit SHA that's stored in a shared s3 bucket that Nomad team developers can access. That commit SHA can be from any branch that's pushed to remote. Ex. -nomad.sha=0b6b475e7da77fed25727ea9f01f155a58481b6c
  • -nomad.version=string: provision this version from releases.hashicorp.com. Ex. -nomad.version=0.10.2

Then deploy Nomad to the cluster by passing -provision.terraform without a Nomad version flag:

NOMAD_E2E=1 go test -v . -nomad.version=0.10.2 -provision.terraform ./provisioning.json -skipTests

Because it can take a little while for the cluster to settle, it's recommended to run this provisioning step (with -skipTests) first, and then run tests as separate step.

Running

After completing the provisioning step above, you can set the client environment for NOMAD_ADDR and run the tests as shown below:

# from the ./e2e/terraform directory, set your client environment
# if you haven't already
$(terraform output environment)

cd ..
go test -v .

If you want to run a specific suite, you can specify the -suite flag as shown below. Only the suite with a matching Framework.TestSuite.Component will be run, and all others will be skipped.

go test -v -suite=Consul .

If you want to run a specific test, you'll need to regex-escape some of the test's name so that the test runner doesn't skip over framework struct method names in the full name of the tests:

go test -v . -run 'TestE2E/Consul/\*consul\.ScriptChecksE2ETest/TestGroup'

I Want To...

...SSH Into One Of The Test Machines

You can use the Terraform output to find the IP address. The keys will in the ./terraform/keys/ directory.

ssh -i keys/nomad-e2e-*.pem ubuntu@${EC2_IP_ADDR}

...Deploy a Cluster of Mixed Nomad Versions

The provisioning.json file output by Terraform has a blank field for nomad_sha for each node of the cluster (server and client). You can manually edit the file to replace this value with a nomad_sha, nomad_local_binary, or nomad_version for each node to create a cluster of mixed versions. The provisioning framework accepts any of the following options for those fields:

  • nomad_sha: This is a Nomad binary identified by its full commit SHA that's stored in a shared s3 bucket that Nomad team developers can access. That commit SHA can be from any branch that's pushed to remote. (Ex. "nomad_sha": "0b6b475e7da77fed25727ea9f01f155a58481b6c")
  • nomad_local_binary: This is a path to a Nomad binary on your own host. (Ex. "nomad_local_binary": "/home/me/nomad")
  • nomad_version: This is a version number of Nomad that's been released to HashiCorp. (Ex. "nomad_version": "0.10.2")

Then deploy Nomad to the cluster by passing -provision.terraform without a Nomad version flag:

go test -v . -provision.terraform ./provisioning.json -skipTests

...Deploy Custom Configuration Files

The provisioning.json file includes a bundles section for each node of the cluster (server and client). You can manually edit this file to add, remove, or replace

"bundles": [
  {
    "destination": "/ops/shared/nomad/base.hcl",
    "source": "/home/me/custom.hcl"
  }
]

...Deploy More Than 4 Linux Clients

Right now the framework doesn't support this out-of-the-box because of the way the provisioning script adds specific client configurations to each client node (for constraint testing). You'll need to add additional configuration files to ./e2e/terraform/shared/nomad/indexed.
