In order to AVOID the MIXED_DML_EXCEPTION error, you can either user an @Future annotation on your createTestUser () method, or you can wrap the execution of this method between a System.runAs (User) method. This User can be yourself for example, querying it like: User runAsUser = [SELECT Id FROM User WHERE Id = :UserInfo.getCurrentUserId ()];
How to avoid mixed-DML-operation error in Salesforce?
if we perform DML operation on standard/custom object records asynchronously (execute in future context), we can avoid MIXED-DML-OPERATION error. To execute logic asynchronously keep the logic in an apex method (in a separate apex class, not in same apex trigger) which is decorated with @future annotation.
How to avoid the mixed DML error in a single transaction?
This example shows how to enclose mixed DML operations within System.runAs blocks to avoid the mixed DML error. The System.runAs block runs in the current user’s context. It creates a test user with a role and a test account, which is a mixed DML operation. Mixed DML operations within a single transaction aren’t allowed.
Why am I getting a speciifc error in my Salesforce tests?

Note that the error doesn't happen when you run the tests from Eclipse/Force.com IDE, but it does happen when you deploy to Salesforce and then run the tests from within Salesforce. How do I re-write my tests to avoid this error?
How do you bypass mixed DML error in test cases?
You can also use the runAs method to perform mixed DML operations in your test by enclosing the DML operations within the runAs block. In this way, you bypass the mixed DML error that is otherwise returned when inserting or updating setup objects together with other sObjects.
How can you avoid mixing DML and test class?
stopTest statements prevents the mixed DML exception error in a test. Because the delete statement causes a mixed DML operation to be executed by a future method, it is enclosed within the Test. startTest and Test. stopTest statements.
How do you avoid mixed DML errors?
To avoid this error, we should perform DML operation on standard/custom object records in a different transaction. In general all the apex classes and apex triggers execute synchronously (execute immediately).
How do you avoid mixed DML in Salesforce?

What is a DML exception?
DML statements return run-time exceptions if something went wrong in the database during the execution of the DML operations. You can handle the exceptions in your code by wrapping your DML statements within try-catch blocks. The following example includes the insert DML statement inside a try-catch block.
How do I fix the mixed DML error in Salesforce?

What is a test method?
Test methods allow for performing mixed Data Manipulation Language (DML) operations that include both setup sObjects and other sObjects if the code that performs the DML operations is enclosed within System.runAs method blocks. You can also perform DML in an asynchronous job that your test method calls. These techniques enable you, for example, to create a user with a role and other sObjects in the same test.
Can you perform DML on a setup sobject and another sobject in the same transaction?
Mixed DML operations within a single transaction aren’t allowed. You can’t perform DML on a setup sObject and another sObject in the same transaction. However, you can perform one type of DML as part of an asynchronous job and the others in other asynchronous jobs or in the original transaction.
