help required in activiti-crystallball module

sadiasher

I run test SimpleSimulationRunTest.java with small changes in its PlaybackProcessStartTest.testUserTask.bpmn20.xml file with user task to service task. I got null task object in record() method, i went through the code but didnt find any clue. Even I read crystal ball getting started from github but thats not a good help.

Any help is highly appreciated.

Hi Martin,

Is there any progress on visual app demo of crystal ball (as i read on thread thats its underconstruction). actually I have a task to make dry run of process using activiti crystal ball. I read provided links and also run provided testcases but these not clear my points. I need to make dry run to allow user to test their process on spot(from modeler using option on toolbar), I cant understand how user knows that its process is successfully executed is that show from diagrams generated by ProcessDiagramGenerator or something else?

or can u tell me the what different colors (red, green, yellow) shows on diagram?

Any help is highly appreciated?

Hi Sadia,

crystalball is library to run simulation experiments. The output can be presented in reports (one of them can be enhanced graphical process model).

I need to make dry run to allow user to test their process on spot(from modeler using option on toolbar),

at first you have to set up simulation experiment. (set of events to be executed in the simulation run - in the case of replay or playback - events are taken from history.)
Test the process -> you have to have assert condition to evaluate the test.

I cant understand how user knows that its process is successfully executed is that show from diagrams generated by ProcessDiagramGenerator or something else?

It depends on the test assertion. Basically in simulation we can evaluate what is the probability that some event occur. User who gets the report must know how to read the report.

or can u tell me the what different colors (red, green, yellow) shows on diagram?

Could you point me to the report?

Hi,

https://raw.github.com/gro-mar/activiti-crystalball/master/examples/src/test/resources/org/activiti/crystalball/examples/mvn/images/mvn-report-2.png

is test coverage report
-> green - process executions went through process step more than 7 times
-> yellow - process executions went through process step 1-7 times
-> red - process step was not tested - no process instance went through it.
