Testing

openstorage supports has multiple ways to test your code. openstorage has unit tests, csi-sanity, and osd-sanity to check the quality of the code.

csi-sanity

csi-sanity is a program provided by the CSI community which assures that the CSI API implementation is correct. This program is executed automatically by unit tests when csi/csisanity_test.go is executed.

osd-sanity

osd-sanity is a tool provided by openstorage which can be used to point to a running instance of a openstorage implementation to make sure it behaves and interacts according to the API.

Unit tests and Golang mock

Running tests

Docker is required for the tests. To run the tests, run:

make docker-test # test within a docker container

Testing manually

To test changes in the library, you could use the NFS driver. Here is how to use it with Docker.

• Build using make install
• Start up your NFS server and expose a share called /nfs
• Run on the osd sample daemon in one window:

sudo $GOPATH/bin/osd -d -f etc/config/config.yaml

Testing with Docker

Assuming you are using the NFS driver, to create a volume with a default size of 1GB and attach it to a Docker container, you can do the following

$ docker volume create -d nfs
9ccb7280-918b-464f-8a34-34e73e9214d2
$ docker run -v 9ccb7280-918b-464f-8a34-34e73e9214d2:/root --volume-driver=nfs -ti busybox

Testing with CSI

To test with csi, use the csc tool from rexray/gocsi.

• Install csc

go install github.com/rexray/gocsi/csc

• Run csc against your driver. Here is an example of running against the NFS example above using v0.2.0 of CSI:

csc controller list-volumes -v 0.2.0 --endpoint /var/lib/osd/driver/nfs-csi.sock
