+## Testing
+
+### Prerequisites
+
+* docker
+* Google Cloud CLI tools ([installation guide](https://cloud.google.com/sdk/docs/install))
+
+### Instructions
+
+From the [upstream usage example](https://kserve.github.io/website/master/modelserving/v1beta1/paddle/), this rock can be tested locally using:
+
+Launch the server with:
+```
+# download the model locally
+mkdir sample_model
+gsutil cp -r gs://kfserving-examples/models/paddle/resnet ./sample_model/
+
+# mount the model into the container at runtime
+docker run -p 8080:8080 -v $(pwd)/sample_model/resnet:/mnt/models paddleserver:<version> --model_name test_model --model_dir=/mnt/models --http_port=8080
+
+```
+
+Test the server with:
+```
+wget https://kserve.github.io/website/master/modelserving/v1beta1/paddle/jay.json -O input.json
+
+curl -v
+  -H "Content-Type: application/json" \
+  -d @./input.json \
+  localhost:8080/v1/models/test_model:predict
+```
+
+which should return the expected output described in the docs.
