Using Serverless-Artillery to test a deployed API endpoint

Installation Guide and Procedure

1. Install aws-cli: (https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-install.html)
2. Install serverless: npm i -g serverless (global) or npm i serverless --save-dev (project-level)
3. Install artillery: npm i -g artillery (global) or npm i artillery --save-dev (project-level)
4. Install serverless-artillery: npm i -g serverless-artillery (global) or npm i serverless-artillery --save-dev (project-level)
5. From command line, navigate to root of project with cd
6. Create script: slsart script -e {URL of endpoint to hit with requests} -d 10 -r 40; this will hit the URL of the function you wish you test for 10 seconds, with a rate of 40 requests per second.
7. Configure AWS-CLI: aws configure; at the prompt, enter the AWS Access Key stored wherever your project keeps its Secrets/Keys; enter the AWS Access Secret (same place as the previous attribute); enter the AWS region which the project is deployed from. The config file should be findable at ~./aws/credentials.
8. Create a "stage": this will provision an AWS LoadGenerator Lambda function which will be used by serverless-artillery to generate load simulation for test. slsart deploy --stage {nameOfStage} --region {regionCodeOfDeployment, e.g. us-west-1}
9. Run script: slsart invoke -o {name of YML script generated by Step 6} | tee {nameOfTestResultsFile.json}; this should pipe the output both to the testResults.json file as well as to stdout.
10. Tear down deployed test assets (i.e. the AWS Lambda): slsart remove --stage {nameOfStage} --region {nameOfDeploymentRegion}
