Probes can be placed into a diagram to monitor values generated by a step's output pin. They can be configured to check those pin values against a wide number of attributes (values are in a range, values are increasing, decreasing, below or above a limit etc.)
The parameters (i.e. limits or range bounds) can either be defined statically, or recorded by a prototypical "good" run through the testsuite.
For this, probes can be set into one of three modes:
- inactive - probes are disabled completely
- recording - probes will record incoming values and adjust their check-parameter(s)
- checking - probes will monitor incoming values and check them against their check-parameter(s)
Probes are placed into the diagram via diagram editor's the pop-up menu.
