Sequence diagrams are a superb aid to understanding behavior. Class collaboration diagrams also can be helpful. In addition to these sometimes a call graph is just what we need. Then again, if you have this information available, you could use it to document a Use Case and why not build a Test domain while you are at it. The Enterprise Architect Analyzer can generate all of these for you and from a single recording. It does this by recording a running program, and it works on all of the most popular platforms.



Execute > Analyze > Recorder > Open Recorder


At its simplest, a Sequence Diagram can be produced in very few steps using even a brand new model. You do not even have to configure an Analyzer Script. Open the Enterprise Architect code editor (Ctrl+Shift+O), place a recording marker in a function of your choice, and then attach the Enterprise Architect debugger to a program running that code. Any time that function is called, its behavior will be captured to form a recording history. From this history these diagrams can be easily created.

The Sequence diagram from the Example Model recording.

The Class collaboration diagram from the same recording.

The Test Domain diagram from the same recording.

Of course an Analyzer Script is still the best idea, and opens up an incredibly rich development environment, but it is worth noting that significant results can be obtained without one. This is also true of the Enterprise Architect Debugger and Profiler tools.

A point of interest: you can view a thread's behavior while it is recorded. Showing the call stack during a recording will show updates to a thread's stack in real-time, much like an animation. It is a good feedback tool and in some circumstances it might be all that is required.
