Fixed - Summer '20

Summary
In an apex test execution, if an email action is invoked in an asynchronous apex call processed prior to another asynchronous apex call which executes a callout, the test fails with a System.CalloutException exception, "You have uncommitted work pending. Please commit or rollback before calling out".

Repro
1. Create a class which has a future method issuing a DML.
public class MyFutureClass {
@Future
public static void asynchronousDml() {
insert new Account(name = 'SFDC');
}
}
2. Create a class which asynchronously executes a callout.
public class MyQueueableClass implements Queueable, Database.AllowsCallouts {
private void executeCallout() {
HttpRequest req = new HttpRequest();
req.setMethod('GET');
req.setEndpoint('http://example.com/';);
HTTPResponse res = new Http().send(req);
}
public void execute(QueueableContext ctx) {
executeCallout();
}}

3. Create a class for the callout test.
@isTest public class CalloutTest{
public class CalloutServiceMock implements HttpCalloutMock {
HttpRequest originalRequest;
HttpRequest getRequest() {
return originalRequest;
}

public HTTPResponse respond(HTTPRequest req) {
HTTPResponse response = new Httpresponse();
response.setBody('OK');
response.setStatusCode(200);
return response;
} }

@isTest static void doTest() {
MyFutureClass.asynchronousDml();
Test.setMock(HttpCalloutMock.class, new CalloutServiceMock());
Test.startTest();
System.enqueueJob(new MyQueueableClass());
Test.stopTest(); } }

4. Create an email alert, does not matter what email template or sender fields.
5. Create a workflow rule to fire on Account with criteria: Name contains “SFDC”. Have WF rule fire the email alert action created in the above step. And activate the WF rule.
6. Run the test, and you'll see the test fails with the System.CalloutException exception.

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

Workaround
N/A

Updates
Updating the test classes to API version 49.0 or above should help the classes benefit from the fix.
