Test Class 'Mixed DML Error'

Hi Gurus,

I have created an Apex Class which creates a User Account (future method) . This Class is called from Process Builder when a custom object record is created.

Now, I am trying to create a Test Class, but I am getting 'MIXED_DML_OPERATION, DML operation on setup object is not permitted after you have updated a non-setup object (or vice versa):'

How to get around this ?

Thanks,

Raghu



Now, I am trying to create a test class for this,

Please check below post. How to resolve this issue

Mixed DML Operations in Apex Class:-
You can perform DML operations on more than one type of sObject in a single class using the following process:
1) Create a method that performs a DML operation on one type of sObject.
2) Create a second method that uses the future annotation to manipulate a second sObject type.

Mixed DML Operations in Test Methods :-
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.
Using Test.startTest and Test.stopTest to bypass the mixed DML error in a Test Method
