How to avoid mixed DML operation error in unit testing?
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. See sObjects That Cannot Be Used Together in DML Operations.
What are the challenges of doing regression testing?
Challenges in Regression Testing: Following are the major testing problems for doing regression testing: With successive regression runs, test suites become fairly large. Determination of frequency of Regression Tests, i.e., after every modification or every build update or after a bunch of bug fixes, is a challenge.

Mixed DML Operations in Test Methods 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.
Can you do mixed DML in one transaction?

As of Summer ’08, you can only perform DML operations on a single type of sObject from the following list of sObjects.
Can you use mixed DML in asynchronous jobs?
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. This class contains an @future method to be called by the class in the subsequent example.
How to trigger a DML exception for test coverage?
You can use FOR UPDATE to lock a certain record, but it would be locked to the testing transaction, so it might not give you the DML Exception you want. How dependant are you on the content of the DML Exception? If you just want an exception of the correct type use Test.isRunningTest () to deliberately cause the exception.
When to perform DML operation on standard / Custom object?
