Python supports registering a function for profiling purposes. Using this mechanism it is possible to add command tracing and "per-command" screenshots to Python test scripts.
An example implementation (called "squish_trace") can be downloaded here .
Here is an example test script that makes use of the squish_trace functionality:
The additional log entries generated by squish_trace:
>>denote entering a function
<<denote exiting a function.
The tooltip of each trace log entry shows the local variables and their values at that point in time, in the above example the variable "i" of the for loop.
