System.CalloutException: Test Webservice future callout from an apex trigger fails if a feeditem is inserted before the callout.

Test methods that make a mock callout to test a webservice invoked via an apex trigger fail with the following error when a Feeditem is inserted(either DML or the connectAPi) before the callout :

"System.CalloutException: You have uncommitted work pending. Please commit or rollback before calling out"

- The code below demos the error both for the connect Api and the DML, please see inline code comments :

1. Create the following components :

Trigger Handler :

public class DummyCalloutService{
public static void doCallout() {
HttpRequest req = new HttpRequest();
Http http = new Http();
HTTPResponse res = http.send(req);

@future (callout=true)
public static void CalloutWithinFuture() {

Trigger :

trigger accTrigger on Account (after insert) {

FeedItem post = new FeedItem();
post.ParentId = userInfo.getUserId();
post.createdById = userInfo.getUserId();
post.Body = 'hello there';
post.type = 'LinkPost';
post.LinkUrl = '';
post.Title = 'New Post';
insert post;

/* Or to test the connectApi use :
ConnectApi.FeedElement feedElement = ConnectApi.ChatterFeeds.postFeedElement(null, userInfo.getUserId() , ConnectApi.FeedElementType.FeedItem, 'On vacation this week.');



Test Class :

@isTest(SeeAllData = false) // SeeAllData = true for testing the connectApi
public class CalloutErrorTest {
public class DummyCalloutServiceMock implements HttpCalloutMock {
HttpRequest originalRequest;
HttpRequest getRequest() {
return originalRequest;

public HTTPResponse respond(HTTPRequest req) {
HTTPResponse response = new Httpresponse();
return response;

static testMethod void insertAcc() {

Test.setMock(HttpCalloutMock.class, new DummyCalloutServiceMock());
insert new account(Name = 'abctest');

4. Run the test.

- You will see this error in the test result : "System.CalloutException: You have uncommitted work pending. Please commit or rollback before calling out"
