Test Mocks

In Apex test classes, all callouts must be mocked including callouts in dependent packages like Rollbar. However, Salesforce doesn't allow adding Test.setMock directly to your code for callouts that are in managed packages.

The following interfaces can be used in your tests to wrap Test.setMock.

To set a default mock:

rollbar.RollbarTestHelper.setDefaultMock();

To provide your own custom mock:

rollbar.RollbarTestHelper.setMock(new CustomMock);

Example:

@isTest
public class CalloutTest {
    @isTest
    public static void calloutIsMocked(){
        // Set the test mock.
        rollbar.RollbarTestHelper.setDefaultMock();

        // Also initialize a test token. (Can be any string.)
        insert new rollbar__RollbarSettings__c(rollbar__AccessToken__c = 'test-token');
        
        Test.startTest();
        // Any Rollbar callouts (e.g. rollbar.Rollbar.log()) should work.
        Test.stopTest();
    }
}
