The present invention comprises methods for testing the valve seating integrity of a valve. The valve components that determine valve seating integrity are typically a valve seat and a valve closing element that engages the valve seat to close the valve. Examples of the test method described herein respectively test valve seating integrity during opening of the valve and during closing of the valve, and do so in all instances without interrupting the operation of a process control system that includes the valve, without isolating the valve, and without relying on user analysis.
