Testing a Rest Web Service in salesforce.com

Question

I am developing a Rest Web service in salesforce.com platform. I wrote it and it is working properly and giving accurate responses when I call it. The problem is how to test it

@RestResource(urlMapping='/feedpost/*')

    global class Feedpost9

    {

      @HttpPut

      global static User updateCase() {

         RestRequest req=RestContext.request;

         User user=[SELECT id from User where email=:req.headers.get('email') LIMIT 1];

         return user;          

    }

}

Now my task is to test this REST web service method updateCase. For testing a POST request method I have to set the parameters in method call but in case of PUT method - how do I set RestContext.request in the test class?

Issues which are needed to be contented with unit tests are:

• The lack of data in a test environment
• The need for a valid RestRequest

The basic technique needed to set up the request object your method wants is:

global class Feedpost9 {

    // your methods here...

    static testMethod void testRest() {

        // set up the request object

        System.RestContext.request = new RestRequest();

        RestContext.request.requestURI = '/feedpost/whatever';

        RestContext.request.addHeader('email', '[email protected]');

        // Invoke the method directly

        Feedpost9.updateCase();

    }

}
