+# JMeter Clowder Tests
+
+This directory includes a simple [JMeter](https://jmeter.apache.org/) test plan to exercise the service and API.
+JMeter includes both a GUI to create and run the test plans as well as a CLI. When stress testing, use the CLI.
+
+Before running the test you will need to set `X-API-KEY` to your own Clowder API key. Change the web server protocol, 
+server name, and port, in HTTP Request Defaults and the file path `File.path` you want to use to test in `Upload file`.
+
+You can set the concurrency by changing the number of threads `ThreadGroup.num_threads` in Scenario 1.
+This scenario includes the following steps:
+- Create dataset
+- Upload file to dataset
+- Create folder
+- Move file to folder
+- Update file name
+- Upload file metadata
+
+There is a 1s pause between each call. Make that shorter or disable if stress testing.
+
+To run the test from the command line use the following command:
+
+`jmeter -n -t jmeter-clowder.jmx -l jmeter-out -e -o jmeter-out-html`
+
+The file `jmeter-out` will include the status of each call. 
+The `jmeter-out-html` will include an html page with summaries and visualizations of that output.
