# @cumulus/integration-tests

[![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`
