+
+[![CircleCI](https://circleci.com/gh/cumulus-nasa/cumulus.svg?style=svg)](https://circleci.com/gh/cumulus-nasa/cumulus)
+
+@cumulus/integration-tests provides a CLI and functions for testing Cumulus workflow executions in a Cumulus deployment.
+
+## What is Cumulus?
+
+Cumulus is a cloud-based data ingest, archive, distribution and management prototype for NASA's future Earth science data streams.
+
+[Cumulus Documentation](https://cumulus-nasa.github.io/)
+
+## Installation
+
+```
+npm install @cumulus/integration-tests
+```
+
+## Usage
+
+```
+Usage: cumulus-test TYPE COMMAND [options]
+
+
+  Options:
+
+    -V, --version                   output the version number
+    -s, --stack-name <stackName>    AWS Cloud Formation stack name (default: null)
+    -b, --bucket-name <bucketName>  AWS S3 internal bucket name (default: null)
+    -w, --workflow <workflow>       Workflow name (default: null)
+    -i, --input-file <inputFile>    Workflow input JSON file (default: null)
+    -h, --help                      output usage information
+
+
+  Commands:
+
+    workflow  Execute a workflow and determine if the workflow completes successfully
+```
+i.e. to test the HelloWorld workflow:
+
+`cumulus-test workflow --stack-name helloworld-cumulus --bucket-name cumulus-bucket-internal --workflow HelloWorldWorkflow --input-file ./helloWorldInput.json`
+
