About

The Playtypus is an eventmachine-based command line utility that plays HTTP calls. A JSON input file (or files) tells The Playtypus what uri, method, headers, and body to send to a host, as well as the precise time to send each call. Optional response logging will write all details of HTTP responses to disk by call sequence.

Usage

1. Install The Playtypus gem

   $ gem install playtypus

2. Define a series of HTTP calls in a JSON file

      [
       {
          "timestamp" : "1970-01-01T00:00:00.0000000000Z",
          "path" : "/v1/users",
          "verb" : "POST",
          "headers" : {
            "Content-Type" : "application/json",
            "X-AUTH-TOKEN" : "123456789"
          },
          "body" : {
            "user" : {
              "name" : "the playtypus",
              "domicile" : "github"
            }
          }
        },
        {
          "timestamp" : "1970-01-01T00:00:01.0000000000Z",
          "path" : "/v1/users/1",
          "verb" : "GET",
          "headers" : {
            "Content-Type" : "application/xml"
          }
        }
      ]
   

3. Tell The Playtpus to play

$ playtypus play --host=http://localhost:8081 --call-log=log.json --response-log=responses/ --preserve-times

Command line arguments

This section describes required and optional arguments The Playtypus understands.

help

Describes available commands or one specific command

--host, -h

(Required) The HTTP protocol to use, as well as the host address to use in playback:

--host=https://169.0.0.1:443/

--call-log, -c

(Required) A file or directory containing a JSON array of calls to play:

--call-log=calls/

--response-log, -r

(Optional) A destination directory for response logs stored in sequence by call:

--response-log=responses/

--preserve-times, --no-preserve-times

(Default=false) Specifies whether timestamps should be used in playback:

--preserve-times

Call logs

Call logs specify arrays of JSON instructing The Playtypus what, as well as when, to play HTTP calls. Five properties are used:

1. timestamp - a string in ISO 8601 format. The initial timestamp matters not--the relative distance between each timestamp defines the distance between two calls.

2. path - a relative path to be appended to the global --host address

3. verb - GET, PUT, POST, DELETE, et cetera

4. headers - a dictionary of headers to send

5. body - a payload in dictionary or string format
