+! Live UML Sequence Diagrams, their building and tests

+
+Kasper Østerbye (kasper.osterbye@gmail.com)
+
+""Abstract:""

+Sequence diagrams are a powerful tool for understanding how objects interact at runtime. This talk presents MicroSequenceDiagram, a Pharo framework that generates live UML sequence diagrams directly from running code — no manual drawing, no static analysis. By tracing actual execution, the diagrams show what really happens, not what the programmer intended.
+
+The talk demonstrates how to build interactive diagrams with drill-down navigation between packages and clickable class documentation. As a secondary topic, we present our tests code for the MicroSequenceDiagram classes and methods — all built by our AI-driven test generator.
