mandyc Help writing unit test for REST class
I have a REST class that creates new lead records. See below:
@RestResource(urlMapping='/v.1/leads/*')
global with sharing class LeadRestSvc {
@HttpPost
global static String doPost(String firstname, String lastname) {
RestRequest req = RestContext.request;
//see if a name was part of the URI
String leadName = req.requestURI.substring(req.requestURI.lastIndexOf('/')+1);
if (leadName == '') {
Savepoint sp = Database.setSavePoint();
try {
//populate a new Lead object
Lead l = new Lead();
l.FirstName = firstname;
l.LastName = lastname;
insert l;
return 'success';
}
catch (DMLException e1) {
Database.rollback(sp);
return e1.getDMLMessage(0);
}
catch (Exception e2) {
Database.rollback(sp);
return e2.getMessage();
}
}
else {
return 'Invalid operation';
}
}Now I need to write a unit test and am having difficulty. I've tried following the few GET examples online but without success.
I tried the following but I get this error : "Compile Error: Option already set: TestMethod "
@isTest
static testmethod void testDoPost(){
RestRequest req = new RestRequest();
RestResponse res = new RestResponse();
req.requestURI = 'https://XXXX.salesforce.com/services/apexrest/v.1/leads/';
req.httpMethod = 'POST';
RestContext.request = req;
RestContext.response = res;
RestContext.request.addHeader('firstname','Wain','lastname','Rolen');
String results = LeadRestSvc.doPost();
} Also, am I supposed to hardcode the requestURI? It seems that the unit test won't work when I try to move this code into my production environment.
I appreciate the assistance!
Hi,
Try to remove the "@isTest" annotation, as my understand and practice, if we have the "testmethod" we can aovid use "@isTest" annotation on method.

Thannk you!
Thank you, JIE!
Now I'm getting the following error on the last line of the unit test: Method does not exist or incorrect signature: LeadRestSvc.doPost(String, String)
any suggestions?
static testmethod void testDoPost(){ RestRequest req = new RestRequest(); RestResponse res = new RestResponse(); req.requestURI = 'https://XXXX.salesforce.com/services/apexrest/v.1/leads/'; req.httpMethod = 'POST'; RestContext.request = req; RestContext.response = res; String results = LeadRestSvc.doPost('Wain','Rolen'); }Thank you
Hi mandyc,
Actually, I just invoke the rest apex method from my external java project. So I can't ensure how to invoke it from another apex test class. But I think there will be some similar between them.
As your know, the rest apex will intercept the request whitch has the following url "/v.1/leads/*", but in your test method, you didn't sent any request, you just set some attribute to a RestResquest instance.
Then you call your doPost method directly.
You can use HTTP method(apply by Salesforce) to send your request.
See an example:
public class HttpCalloutSample { // Pass in the endpoint to be used using the string url public String getContent(String url) { // Instantiate a new http object Http h = new Http(); // Instantiate a new HTTP request, specify the method (GET) as well as the endpoint HttpRequest req = new HttpRequest(); req.setEndpoint(url); req.setMethod('GET'); // Send the request, and return a response HttpResponse res = h.send(req); return res.getBody(); } }I do the same thing in my java code, I use the HttpClient class to send request to my rest apex.
Thank you!
