Integration Testing

Integration test verifies the functionality of EBS CSI driver as a standalone server outside Kubernetes. It exercises the lifecycle of the volume by creating, attaching, staging, mounting volumes and the reverse operations. And it verifies data can be written onto an EBS volume without any issue.

Run Integration Tests Locally

The integration test is executed using aws-k8s-tester which is CLI tool for k8s testing on AWS. With aws-k8s-tester, it automates the process of provisioning EC2 instance, pulling down and building EBS CSI driver, running the defined integration test and sending test result back. See aws-k8s-tester for more details about how to use it.

Requirements

  1. AWS credential is configured
  2. Other requirements needed by aws-k8s-tester
make test-integration

Overriding Defaults

  • The master branch of aws-ebs-csi-driver is used by default. To run using a pull request for aws-ebs-csi-driver, set PULL_NUMBER as an environment variable with a value equal to the pull request number.

  • When the tests are run, a new Amazon Virtual Private Cloud (VPC) is created by default. To run using an existing VPC, set AWS_K8S_TESTER_VPC_ID as an environment variable with a value equal to an existing VPC ID. This will be useful when VPC limit is reached in the region under test.
