Added two new parameters for e2e test to skip rbd and cephfs tests. This will help us to run more test in Travis CI. Signed-off-by: Madhu Rajanna <madhupr007@gmail.com>

## Introduction
|
|
|
|
End-to-end (e2e) in cephcsi provides a mechanism to test the end-to-end
|
|
behavior of the system, These tests will interact with live instances of ceph
|
|
cluster just like how a user would.
|
|
|
|
The primary objectives of the e2e tests are to ensure a consistent and reliable
|
|
behavior of the cephcsi code base and to catch hard-to-test bugs before
|
|
users do when unit and integration tests are insufficient.
|
|
|
|
The Test framework is designed
|
|
to install Rook, run cephcsi tests, and uninstall Rook.
|
|
|
|
The e2e test are built on top of [Ginkgo](http://onsi.github.io/ginkgo/) and
|
|
[Gomega](http://onsi.github.io/gomega/)
|
|
|
|
## Install Kubernetes
|
|
|
|
The cephcsi also provides a script for starting Kubernetes using
|
|
[minikube](../scripts/minikube.sh) so users can quickly spin up a Kubernetes
|
|
cluster.
|
|
|
|
the following parameters are available to configure kubernetes cluster
|
|
|
|
| flag | description |
|
|
| ----------------- | ------------------------------------------------------------- |
|
|
| up | Starts a local kubernetes cluster and prepare a disk for rook |
|
|
| down | Stops a running local kubernetes cluster |
|
|
| clean | Deletes a local kubernetes cluster |
|
|
| ssh | Log into or run a command on a minikube machine with SSH |
|
|
| deploy-rook | Deploy rook to minikube |
|
|
| create-block-pool | Creates a rook block pool (named $ROOK_BLOCK_POOL_NAME) |
|
|
| delete-block-pool | Deletes a rook block pool (named $ROOK_BLOCK_POOL_NAME) |
|
|
| clean-rook | Deletes a rook from minikube |
|
|
| cephcsi | Copy built docker images to kubernetes cluster |
|
|
| k8s-sidecar | Copy kubernetes sidecar docker images to kubernetes cluster |
|
|
|
|
following environment variables can be exported to customize kubernetes deployment
|
|
|
|
| ENV | Description | Default |
|
|
|----------------------|--------------------------------------------------|--------------------------------------------------------------------|
|
|
| MINIKUBE_VERSION | minikube version to install | latest |
|
|
| KUBE_VERSION | kubernetes version to install | v1.14.10 |
|
|
| MEMORY | Amount of RAM allocated to the minikube VM in MB | 3000 |
|
|
| VM_DRIVER | VM driver to create virtual machine | virtualbox |
|
|
| CEPHCSI_IMAGE_REPO | Repo URL to pull cephcsi images | quay.io/cephcsi |
|
|
| K8S_IMAGE_REPO | Repo URL to pull kubernetes sidecar images | quay.io/k8scsi |
|
|
| K8S_FEATURE_GATES | Feature gates to enable on kubernetes cluster | BlockVolume=true,CSIBlockVolume=true,VolumeSnapshotDataSource=true |
|
|
| ROOK_BLOCK_POOL_NAME | Block pool name to create in the rook instance | newrbdpool |
|
|
|
|
- creating kubernetes cluster
|
|
|
|
```console
|
|
$./minikube.sh up
|
|
```
|
|
|
|
- Teardown kubernetes cluster
|
|
|
|
```console
|
|
$./minikube.sh clean
|
|
```
|
|
|
|
## Test parameters
|
|
|
|
In addition to standard go tests parameters, the following custom parameters
|
|
are available while running tests:
|
|
|
|
| flag | description |
|
|
| ----------------- | ----------------------------------------------------------------------------- |
|
|
| deploy-timeout | Timeout to wait for created kubernetes resources (default: 10 minutes) |
|
|
| deploy-cephfs | Deploy cephfs csi driver as part of E2E (default: true) |
|
|
| deploy-rbd | Deploy rbd csi driver as part of E2E (default: true) |
|
|
| test-cephfs | Test cephfs csi driver as part of E2E (default: true) |
|
|
| test-rbd | Test rbd csi driver as part of E2E (default: true) |
|
|
| cephcsi-namespace | The namespace in which cephcsi driver will be created (default: "default") |
|
|
| rook-namespace | The namespace in which rook operator is installed (default: "rook-ceph") |
|
|
| kubeconfig | Path to kubeconfig containing embedded authinfo (default: $HOME/.kube/config) |
|
|
| timeout | Panic test binary after duration d (default 0, timeout disabled) |
|
|
| v | Verbose: print additional output |
|
|
|
|
## Running E2E
|
|
|
|
`
|
|
Note:- Prior to running the tests, you may need to copy the kubernetes configuration
|
|
file to `$HOME/.kube/config` which is required to communicate with kubernetes
|
|
cluster or you can pass `kubeconfig`flag while running tests.
|
|
`
|
|
|
|
Functional tests are run by the `go test` command.
|
|
|
|
```console
|
|
$go test ./e2e/ -timeout=20m -v -mod=vendor
|
|
```
|
|
|
|
Functional tests can be invoked by `make` command
|
|
|
|
```console
|
|
$make func-test TESTOPTIONS="--deploy-timeout=10 -timeout=30m -v"
|
|
```
