Titanium: Visualization of TTCN-3 system architecture

Abstract

To help the work of TTCN-3 test system architects we created a tool that is able to visualize large test systems, fitting to daily work practices. We defined and implemented 2 layouts, clustering and interaction methods. We also show 2 structuring methods, that are not yet supported by the TTCN-3 standard. With this tool we have analyzed all standardized test suites available at www.ttcn3.org, finding circular dependency and unnecessary source files in almost every test suite.
