Summary 0007111: [RFE] SUnit support for testing infinite recursion loop
Description I propose to add following extension:

self should: [myObject doSomething] notSendDeeperThan: 10000.
Additional Information I propose a MessageTally-spy-like solution to this.

I'm still interested if anyone finds a way to assert infinite ITERATIVE loops (whileTrue and whileFalse...)

Note that this solution does not handle correctly an Error...
An Error would pass...
Up to Block/Exception gurus to give their advice.

Since squeak-dev thread tend to show i was misunderstood, I add a few complements:
My aim is not to solve the halting problem! This is not possible.
I don't want to fight against maths, logic nor Godel.

I just want to be able to count loops so that I can provide a hint and decide to stop the test.

Monitoring resources consumption (CPU and memory) at an upper level would be of greater interest than this partial support...
