 We were all saddened and shocked by the sudden disappearance of the `left-pad` NPM module. We were lost and unable to left-pad our strings, until one adventurous person decided to develop a RESTful API to offer that same functionality under a revolutionary new technology called SMaaS (String Manipulation as a Service).

 similarly to the previous example, this will print `#########hello world`.
 
+### Testing
+
+Tests are handled by [mochajs](http://mochajs.org/). To install with npm:
+```
+npm install -g mocha
+```
+
+To run tests simply:
+```
+npm test
+```
+
+### Docker
+
+If you wish to run test without installing anything on your local machine, run it behind a [docker](https://www.docker.com/) container. 
+
+Just build your image
+```
+docker build -t leftpad .
+```
+
+And run it
+```
+docker run leftpad
+```
+
 That's all.
