@saad-ali I updated dependency to csi 0.3.0, let me know what exactly needed to close #13

[jsafrane]

$ go test $(go list ./... | grep -v vendor)
# github.com/kubernetes-csi/livenessprobe/cmd
cmd/livenessprobe_test.go:25:2: cannot find package "github.com/golang/mock/gomock" in any of:
	/home/travis/gopath/src/github.com/kubernetes-csi/livenessprobe/vendor/github.com/golang/mock/gomock (vendor tree)
	/home/travis/.gimme/versions/go1.9.7.linux.amd64/src/github.com/golang/mock/gomock (from $GOROOT)
	/home/travis/gopath/src/github.com/golang/mock/gomock (from $GOPATH)

But I can see vendor/github.com/golang/mock/gomock in the PR...
