I am a bit new to development, but I have a apex rest web service class in my org that people can make calls to. However im not quite sure how to write test classes for this class to ensure 75% score. I have read a bit on the doc on how to do that but Im confused.
Could someone please assist on how I could do the test on this code:
@RestResource(urlMapping='/cs/api/v1/*')
global with sharing class RESTCandidateSourcingManagementService {
@HttpPost
global static Id postData() {
RestRequest req = RestContext.request;
RestResponse res = RestContext.response;
Id returnId;
//Determine which function to perform based on URI
String URI = req.requestURI.substring(req.requestURI.lastIndexOf('/') + 1);
if (URI.equals('candidate')) {
String jid = req.params.get('jid');
System.debug(req.params.get('jid'));
if (jid != null) {
//Post new candidate
returnId = postCandidate(jid, req);
}
} else
if (URI.equals('jobRequisition')) {
//Post new jobRequisition
returnId = postJob(req);
}
return returnId;
}
public static Id postCandidate(String jid, RestRequest restRequest) {
System.debug('>>>Begin processing Candidate request');
RestRequest req = restRequest;
String JSONBody = req.requestBody.toString();
//Variables
PCandidate c;

I have used the docs and have produced something but I see in the code coverage section I have 0% for the class above. Below is my code:
My MockHttpResponseGenerator Class
@isTest
global class MockHttpResponseGenerator implements HttpCalloutMock {
//Implement this interface method
global HTTPResponse respond(HTTPRequest req) {
// Optionally, only send a mock response for a specific endpoint and method.
System.assertEquals('https://pfdev.envisionme.co.za/api/v1/candidate', req.getEndpoint());
System.assertEquals('POST', req.getMethod());
// Create a fake response
HttpResponse res = new HttpResponse();
res.setHeader('Content-Type', 'application/json');
res.setBody('{"foo":"bar"}');
res.setStatusCode(200);
return res;
}
}
My Callout Class
public with sharing class CalloutClass {
public static HttpResponse getInfoFromExternalService() {
HttpRequest req = new HttpRequest();
req.setEndpoint('https://pfdev.envisionme.co.za/api/v1/candidate');
req.setMethod('POST');
Http h = new Http();
HttpResponse res = h.send(req);
return res;
}
}
My CalloutClassTest Class
@isTest
private class CalloutClassTest {
static testMethod void testCallout() {
// Set mock callout class
Test.setMock(HttpCalloutMock.class, new MockHttpResponseGenerator());
// Call method to test.
// This causes a fake response to be sent from the class that implements HttpCalloutMock.
HttpResponse res = CalloutClass.getInfoFromExternalService();
// Verify response received contains fake values
String contentType = res.getHeader('Content-Type');
System.assert(contentType == 'application/json');
String actualValue = res.getBody();
String expectedValue = '{"foo":"bar"}';
System.assertEquals(actualValue, expectedValue);
System.assertEquals(200, res.getStatusCode());
}
}
