A mobile agent is an autonomous software module that can work on different computers and migrate among these computers.
The characteristics of a mobile agent, migration and interaction, are helpful to implement distributed systems.
In the real world, however, a mobile agent is not widely used because its migration makes debugging distributed systems difficult.
Therefore, in this paper, we discuss problems in debugging a mobile agent system and propose a framework that includes a search, a single-step execution, and a reproduction function to help programmers debug a mobile agent system.
Results from our experiments on debugging test applications show that our framework is helpful to support programmers and help them to debug.
This reduces the number of keystrokes by 41% and number of clicks by 24%.
