Requirements

• node.js (tested with v0.6.x and v0.8.x)

Packaged

• coffee-script
• JS-YAML for loading yaml files

Optional (for debugging/testing)

• node-inspector
• jasmine-node

Installation

via source

git clone git://github.com/Afmrak/stubby4node.git
cd stubby4node
cake build

via npm

npm install -g stubby

This will create the executable stubby in the root level of the project.

Starting the Server(s)

Some systems require you to sudo before running services on port certain ports (like 80)

[sudo] stubby

Command-line switches

stubby [-s <port>] [-a <port>] [-f <file>] [-l <hostname>] [-h] [-v]
-s, --stub [PORT]                    Port that stub portal should run on. Defaults to 8882
-a, --admin [PORT]                   Port that admin portal should run on. Defaults to 8889
-f, --file [FILE.{json|yml|yaml}]    Data file to pre-load endoints.
-l, --location [HOSTNAME]            Host at which to run stubby.
-h, --help                           This help text.
-v, --version                        Print stubby's version.

The Admin Portal

The admin portal is a RESTful(ish) endpoint running on localhost:8889.

Supplying Endpoints to Stub

Submit POST requests to localhost:8889 or load a file (-f) with the following structure:

• request: describes the client's call to the server
  • method: GET/POST/PUT/DELETE/etc.
  • url: the URI string. GET parameters should also be included inline here
  • headers: a key/value map of headers the server should respond to
  • post: a string matching the textual body of the response.
• response: describes the server's response to the client
  • headers: a key/value map of headers the server should use in it's response
  • latency: the time in milliseconds the server should wait before responding. Useful for testing timeouts and latency
  • body: the textual body of the server's response to the client
  • status: the numerical HTTP status code (200 for OK, 404 for NOT FOUND, etc.)

YAML (file only)

-  request:
      url: /path/to/something
      method: POST
      headers:
         authorization: "Basic usernamez:passwordinBase64"
      post: this is some post data in textual format
   response:
      headers:
         Content-Type: application/json
      latency: 1000
      status: 200
      body: You're request was successfully processed!

-  request:
      url: /path/to/anotherThing?a=anything&b=more
      method: GET
      headers:
         Content-Type: application/json
      post:
   response:
      headers:
         Content-Type: application/json
         Access-Control-Allow-Origin: "*"
      status: 204
      body:

-  request:
      url: /path/to/thing
      method: POST
      headers:
         Content-Type: application/json
      post: this is some post data in textual format
   response:
      headers:
         Content-Type: application/json
      status: 304
      body:

JSON (file or POST/PUT)

[
  {
    "request": {
      "url": "/path/to/something", 
      "post": "this is some post data in textual format", 
      "headers": {
         "authorization": "Basic usernamez:passwordinBase64"
      },
      "method": "POST"
    }, 
    "response": {
      "status": 200, 
      "headers": {
        "Content-Type": "application/json"
      },
      "latency": 1000,
      "body": "You're request was successfully processed!"
    }
  }, 
  {
    "request": {
      "url": "/path/to/anotherThing?a=anything&b=more", 
      "headers": {
        "Content-Type": "application/json"
      },
      "post": null, 
      "method": "GET"
    }, 
    "response": {
      "status": 204, 
      "headers": {
        "Content-Type": "application/json",
        "Access-Control-Allow-Origin": "*"
      }, 
      "body": null
    }
  }, 
  {
    "request": {
      "url": "/path/to/thing", 
      "headers": {
        "Content-Type": "application/json"
      },
      "post": "this is some post data in textual format", 
      "method": "POST"
    }, 
    "response": {
      "status": 304, 
      "headers": {
        "Content-Type": "application/json"
      }, 
      "body": null
    }
  }
]

If you want to load more than one endpoint via file, use either a JSON array or YAML list (-) syntax. On success, the response will contain Content-Location in the header with the newly created resources' location

Getting the Current List of Stubbed Responses

Performing a GET request on localhost:8889 will return a JSON array of all currently saved responses. It will reply with 204 : No Content if there are none saved.

Performing a GET request on localhost:8889/<id> will return the JSON object representing the response with the supplied id.

Change existing responses

Perform PUT requests in the same format as using POST, only this time supply the id in the path. For instance, to update the response with id 4 you would PUT to localhost:8889/4.

Deleting responses

Send a DELETE request to localhost:8889/<id>

The Stub Portal

Requests sent to any url at localhost or localhost:8882 will search through the available endpoints and, if a match is found, respond with that endpoint's response data

Running tests

If you don't have jasmine-node already, install it:

npm install -g jasmine-node

From the root directory run:

jasmine-node --coffee spec

TODO

• PUTing multiple responses at a time.
• SOAP request/response compliance
• Dynamic port switching
• HTTP/SSL auth mocking
• Randomized responses based on supplied pattern (exploratory QA abuse)
