 # Memcached Operator
 
 ## Overview
+
 This Memcached operator is a simple example operator for the [Operator SDK][operator_sdk] and includes some basic end-to-end tests.
 
 ## Quick Start
+
 This quick start guide walks through the process of building the memcached-operator and running its end-to-end tests.
 
 ### Prerequisites
+
 - [dep][dep_tool] version v0.5.0+.
 - [go][go_tool] version v1.10+
 - [docker][docker_tool] version 17.03+
 - Access to a kubernetes v1.9.0+ cluster
 
 ### Install the Operator SDK CLI
+
 First, checkout and install the operator-sdk CLI:
+
 ```
 $ cd $GOPATH/src/github.com/operator-framework/operator-sdk
 $ git checkout master // currently, there are no releases that include the test framework, so use the master for now

 ```
 
 ### Initial Setup
+
 Checkout this Memcached Operator repository
+
 ```
 $ mkdir $GOPATH/src/github.com/operator-framework
 $ cd $GOPATH/src/github.com/operator-framework
 $ git clone https://github.com/operator-framework/operator-sdk-samples.git
 $ cd operator-sdk-samples/memcached-operator
 ```
+
 Vendor the dependencies
+
 ```
 $ dep ensure
 ```
 
 ### Build the operator
-Build the Memcached operator image and push it to a public registry, such as quay.io
+
+Build the Memcached operator image and push it to a public registry, such as quay.io:
+
 ```
 $ export IMAGE=quay.io/example-inc/memcached-operator:v0.0.1
 $ operator-sdk build $IMAGE
 $ docker push $IMAGE
 ```
 
 ### Run the tests
-Run the tests that reside in test/e2e:
+
+To run the tests in `test/e2e`, first make sure to update the image name from `REPLACE_IMAGE`
+to your desired image name in `deploy/operator.yaml`:
+
+```
+$ sed "s@REPLACE_IMAGE@$IMAGE@g" -i deploy/operator.yaml
+```
+
+Run the tests that reside in `test/e2e`:
+
 ```
-$ operator-sdk test --test-location ./test/e2e --kubeconfig $HOME/.kube/config
+$ operator-sdk test local ./test/e2e
 ```
 
 To run go-test with verbose and limit to 2 parallel tests:
+
+```
+$ operator-sdk test local ./test/e2e --go-test-flags "-v -parallel=2"
+```
+
+To run the tests from an image in the cluster, first build the tests into your image:
+
+```
+$ operator-sdk build $IMAGE --enable-tests
+$ docker push $IMAGE
+```
+
+Then, configure the testing environment:
+
+```
+$ export NAMESPACE="my-test"
+$ kubectl create deploy/crd.yaml -n $NAMESPACE
+$ kubectl create deploy/sa.yaml -n $NAMESPACE
+$ kubectl create deploy/rbac.yaml -n $NAMESPACE
+```
+
+Finally, run the tests:
 ```
-$ operator-sdk test --test-location ./test/e2e --kubeconfig $HOME/.kube/config --go-test-flags "-v -parallel=2"
+$ operator-sdk test cluster $IMAGE --namespace $NAMESPACE --service-account memcached-operator
 ```
