+* `-k, --kubeconfig` string - location of kubeconfig for kubernetes cluster
+* `-c, --crd` string - location of CRD manifest yaml file
+* `-r, --rbac` string - location of RBAC manifest yaml file
+* `-o, --operator` string - location of Operator manifest yaml file
+* `-g, --go-test-flags` string - extra arguments to pass to `go test` (e.g. -g "-v -parallel=2")

+### Use
+
+The operator-sdk test command runs go tests built using the Operator SDK's test framework.

 ## Test Workflow
-1. Run unit tests
-2. Ensure proper formatting
-3. Install the sdk
-4. Create memcached operator from [user-guide.md](https://github.com/operator-framework/operator-sdk/blob/master/doc/user-guide.md#build-and-run-the-operator)
-5. Fill out handler.go and types.go
-6. Generate and build the operator for k8s
-7. Run the deployment
+1. Build the operator-sdk binary
+2. Run unit tests
+3. Run end-to-end tests
+  - Memcached: Creates the example memcached-operator project using the operator-sdk
+    - Cluster: Runs the example memcached-operator in the cluster and spins up 3 memcached containers in a deployment and verifies that all 3 are available.
+    It then scales the deployment to 4 containers and verifies that there are 4 available containers in the deployment
+    - Local: Same as cluster test, but runs the operator using `up local` instead of in a deployment in the cluster.
+4. Ensure proper formatting
+5. Ensure all go files contain a license header
+6. Ensure all error messages have consistent capitalization
