The document outlines an agenda for a knowledge-sharing session on Java UI unit testing with Jemmy. The agenda includes an introduction to Jemmy, how it works, its API usage, unit testing with Jemmy, future integrations, and a Q&A. Jemmy is a Java library for creating automated tests for Java GUI applications. It allows simulating user operations on components by calling events and searching components recursively. The Jemmy workflow involves finding controls, performing actions, and verifying results.

5. • Test Harness
Meaning it is not a tool for test execution.
Any harness which is able to execute tests
written in Java (such as JUnit, for example)
could be used to execute tests.
• Record-Replaying Tool

• simulate user operations on components by calling
events
• search components recursively by given criteria
• criteria defined as implementation of
