The Sleepy Server is a simple software testing utility. The server will sleep for the period specified in the incoming request before it responds.
The only API method takes a single parameter:
http(s)://sleepy.server.org/:sleepValueWhere :sleepValue determines the period that the server will wait before sending a response.
The length of the delay is calculated as the :sleepValue multiplied by the valueMultiplier environment variable (which defaults to 1000 - and as such, we can say that the length of the delay is counted in milliseconds)
Use the 'standard' method to launch the Docker Image from the root directory of the project:
docker build -t sleepy:test .With a :sleepValue of 5 (and the default multiplyer = 1000)
$ date; time http http://localhost:3000/5 -b; date

Leaving this value set to the default of 1000 makes:sleepValueroughly equal to a number of seconds.
