This document provides instructions for using the TestLink Integrator tool to update test case statuses in TestLink from automated tests executed in TestNG. The tool listens for test results from TestNG tests, identifies the associated TestLink test case IDs, and updates the statuses in TestLink. It requires configuring a TestLink project with a test plan and build, marking test cases as automated, and setting the TestLink ID in each TestNG test method. The document outlines the setup and configuration needed to use the tool to integrate TestLink and TestNG test automation.
