Fixed - Winter '17 Patch 12.0

In apex test implementing mock callout, if a transaction performs a DML operation and an email notification (e.g. email alert) is involved, the following exception will be thrown on attempting an Apex callout:

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

1) Create the following Apex class:

public class CalloutService {
@future (callout=true)
public static void docall() {
HttpRequest req = new HttpRequest();
Http http = new Http();
HTTPResponse res = http.send(req);

2) Create the following test class:

public class CalloutTest{

public class CalloutServiceMock implements HttpCalloutMock {
HttpRequest originalRequest;
HttpRequest getRequest() {
return originalRequest;
public HTTPResponse respond(HTTPRequest req) {
HTTPResponse response = new Httpresponse();
return response;
static testMethod void myMethod() {
Account Acc = new Account(name = 'SFDC');
insert Acc;
Test.setMock(HttpCalloutMock.class, new CalloutServiceMock());

3) Create an email alert. Email template or sender fields are not relevant.
4) Create a workflow rule to fire on account with criteria: Name contains “SFDC”. Have WF rule fire the email alert action created in step 3. Activate WF rule.

5) Open CalloutTest Apex class, and hit Run Test. The test will fail:

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

a) If the workflow rule is deactivated, the test will pass.
b) If instead of an email alert, the workflow rule performs a field update that changes record ownership and notifies assignee, the issue will also be reproducible.

a) Separate DML and email notification in different transactions


b) Deactivate email alerts/field update notifications
