Comparing the Contents of TestStand Containers

Overview

This example compares two containers of the same custom data type and returns all of the differences between them.

Description

TestStand has the ability to check if two containers are equal by using the '==' operator within an expression.  However, this does not indicate what fields are different between the containers.  The attached sequence and LabVIEW VI take two variables of the same custom data type, parses through all sub-elements of each variable, and returns the names of all sub-elements that are different.  If one of the sub-elements is an array, the VI first checks if the arrays in each variable are the same size, returns the name of the array if they are not, and checks each individual element if they are.
