Integration Tests

The integration tests run end-to-end tests on Rook in a running instance of Kubernetes. The framework includes scripts for starting Kubernetes so users can quickly spin up a Kubernetes cluster. The tests are generally designed to install Rook, run tests, and uninstall Rook.

The CI runs the integration tests with each PR and each master or release branch build. If the tests fail in a PR, access the tmate for debugging.

This document will outline the steps to run the integration tests locally in a minikube environment, should the CI not be sufficient to troubleshoot.


The CI is generally much simpler to troubleshoot than running these tests locally. Running the tests locally is rarely necessary.


A risk of running the tests locally is that a local disk is required during the tests. If not running in a VM, your laptop or other test machine could be destroyed.

Install Minikube

Follow Rook's developer guide to install Minikube.

Build Rook image

Now that the Kubernetes cluster is running we need to populate the Docker registry to allow local image builds to be easily used inside Minikube.

eval $(minikube docker-env -p minikube)

make build will now build and push the images to the Docker registry inside the Minikube virtual machine.

make build

Tag the newly built images to rook/ceph:local-build for running tests, or rook/ceph:master if creating example manifests::

docker tag $(docker images|awk '/build-/ {print $1}') rook/ceph:local-build
docker tag rook/ceph:local-build rook/ceph:master

Run integration tests

Some settings are available to run the tests under different environments. The settings are all configured with environment variables. See environment.go for the available environment variables.

Set the following variables:

export TEST_HELM_PATH=/tmp/rook-tests-scripts-helm/linux-amd64/helm
export TEST_SCRATCH_DEVICE=/dev/vdb

Set TEST_SCRATCH_DEVICE to the correct block device name based on the driver that's being used.


If using the virtualbox minikube driver, the device should be /dev/sdb


The integration tests erase the contents of TEST_SCRATCH_DEVICE when the test is completed

To run a specific suite, specify the suite name:

go test -v -timeout 1800s -run CephSmokeSuite

After running tests, see test logs under tests/integration/_output.

To run specific tests inside a suite:

go test -v -timeout 1800s -run CephSmokeSuite -testify.m TestARookClusterInstallation_SmokeTest


Only the golang test suites are documented to run locally. Canary and other tests have only ever been supported in the CI.

Running tests on OpenShift

  1. Setup OpenShift environment and export KUBECONFIG
  2. Make sure oc executable file is in the PATH.
  3. Only the CephSmokeSuite is currently supported on OpenShift.
  4. Set the following environment variables depending on the environment:

    export TEST_ENV_NAME=openshift
    export TEST_STORAGE_CLASS=gp2
    export TEST_BASE_DIR=/tmp
  5. Run the integration tests
