The Rook Test Framework is a Go project that that uses a Docker container with Kubernetes tools and Docker pre-installed to quickly create a three node Kubernetes cluster using Docker in Docker (DinD) techniques, installs Rook and then runs automation tests to verify its functionality.

Requirements

Docker version => 1.2 && < 17.0
Ubuntu Host 16 (currently the framework has only been tested on this version)

Instructions

On your Ubuntu box do the following;

Be sure to allocate a minimum of 4 processors to your vm
Navigate to the root directory of the repo and run the following: e2e/scripts/smoke_test.sh

At this point a Docker container with the base image of quay.io/quantum/rook-test is created, a Kubernetes three node cluster is created using Kubeadm, that is visible from the Docker host. The nodes can be identified by the following container names (kube-master, kube-node1 and kube-node2). All tests with the name SmokeSuite in the method will execute and the results will be of a junit type output to the e2e/results directory.

Run Tests

Rook Framework as several configuration options, that can be used to run install rook and run tests, or just run tests against rook that is already installed.

Test parameters

The following parameters are available while running tests

Parameter	Description	Possible values	Default
rook_platform	platform rook needs to be installed on	kubernetes	kubernetes
k8s_version	version of Kubernetes to be installed	v1.6	v1.6
rook_version	rook version/tag to be installed	valid rook tag	master-latest
skip_install_rook	skips installing rook (if already installed)	true or false	false

if install_rook flag is set to false, then all the other flags are ignored, and tests are run without rook being installed and set up. Use this flag to run tests against a pre-installed/configured rook.

Test set up

Run glide install on dir ~e2e/

Install Rook and run Test

To install rook and run tests use the command

go test -run TestObjectStorageSmokeSuite github.com/rook/rook/e2e/tests/smoke

This uses the default --skip_install_rook=false flag. Then Based on other flags, rook is installed and tests are run. e.g.

go test -run TestObjectStorageSmokeSuite github.com/rook/rook/e2e/tests/smoke --rook_version=v3.0.1

Run Tests on pre-installed/exisitng Rook

To run tests against a pre-installed rook set --skip_install_rook=true . Setting skip_install_rook to true will ignore all other flags and run tests without installing rook first.

e.g.

go test -run TestFileStorageSmokeSuite github.com/rook/rook/e2e/tests/smoke --skip_install_rook=true

Prerequisites :

Go installed and GO_PATH set up
Glide installed
when running tests locally, make sure Kubectl is accessible globally, test framework uses kubectl to do setup work.
You can run tests using IDE of your choice, the the flags are configured in e2e/framework/objects/environment_manifest.go file. Update the file to set default values as you see fit and then run tests from IDE directly.

Cleanup

The Rook Test Framework normally cleans up all the containers it creates to setup the environment and to run the tests. If for some reason the cleanup of the Rook Test framework should fail, the easiest way to manually cleanup the environment is by doing the following

Delete the docker container that uses an image named quay.io/rook/rook-test
Run the script rook/e2e/framework/manager/scripts/rook-dind-cluster-v1.6.sh clean
