Data Agent

Purpose

The Data Agent manages reading and writing of input/output values stored in memory during test execution. It is primarily used for data-driven testing, enabling separation of test logic and test data.

Data Agent Blocks

1. Read Parameter

Reads a parameter value from the ETD file using the specified Data ID.

Properties
