pua.js

An unit test library for RESTful API. The main goals of this library are to make unit test script simple and intuitive. It makes your test code easy to create, read and maintaince.

All the test cases are running in the order they are added. New test cases can be added dynamically.

The result from a test case can be set to a collection in stead of passing to next test case by parameters to make handler funciton simple.

Examples for version 2.0.x

The version 1 is still not so convenient. I revised it to version 2. It use a better way to add test case. One test case is an array of parameters. All the usage are shown in the following example. It will stop when any test case with bad syntax.

/*********************************
Terms used in examples:
 - actor: object, user object including { "id": "[email protected]", "auth": "authorization_string" }
 - action: string, request description, for example "get my contact".
 - reqUrl: string, request method and URL, for example "GET /my/contact".
 - expect: number, expect response status code as 200. The default value is 200
 - payload: JSON, text or Buffer. 
 - handler: a function with prototype function(err, res, t). This function MUST be a synchronous function.
 - headers: object, extra request headers other than Authorization, for example {"content-type": "image/jpeg"}.
