I have some concerns about Hydrotest and leak test as below:

1. For Hydrotest, we set up in basic load case like this : W+HP , Stress Type is "HYD" and Hanger Stiffness is "Regid"

I have seen some calculation reports that's different from above like: W+HP, Stress Type is "SUS" and Hanger Stiffness is "As Design"

My question is how's different between these?

2.In stead of Hydrotest, we use leak test on our system.
Could you please tell me how to make this test?
-Is this possible to set up load case W+P2, Stress Type is "SUS" and Hanger Stiffness is "As Design" with P2 is test pressure ( 110% Design pressure P1)?
