Hints with simulation configuration about json-data-generator

[andrewserff]

From what it sounds like, you want to generate a number of events and generate them in order. This is definitely doable with this framework. You can also simulate multiple users. If you take a look at the exampleWorkflow.js in the src/dist/conf directory, you see that this workflow simulates a person entering a building, logging into a computer, performing some random actions, and then logging out and leaving. The events are generated in the order they are placed in the config's steps property.

To have multiple users you would create multiple Workflows (if you wanted them to be different) and then list them in the Sim Config workflows. Then both of those workflows will run when the simulation starts.

You mentioned a "cursor" and the is a type of cursor, but only within an event. See the this.propName and cur.propName sections of the documentation. These allow you to reference already generated values, but only within the current json event being generated. You can't currently reference values within a previously generated event unfortunately.

Hope this helps! If not, let me know.

Hi Andrew, thanks for the promptly reply. In the exempleWorkflow.js, the user enters the build, logs in, performs a single action and leave.

how would you do have a random number of actions for a given step instead of a single action? is, user enters build (1 step/1 event), logs in (1 step/1 event), performs a random number of actions (1 step/N events)? Is it possible?

Thanks again for the help

Yes, that's possible. Check out the Step's duration config option in the documentation. It gives you the different ways to set it for what you want.

Hi Andrew,

One last question, is it possible to format dates and numbers? I tried date().toString('yyyy/MM/dd') but it has no effect.

If you allow me a feature suggestion, it would be great to have a put/get function to add into a kind of session object, allowing us to share some values in running workflow. Something like:

steps:[
{config:[{ "birthdate": "put(date(),'birthday')"},{...},{...}]},
{config:[{"userBirthdate":"get('birthday')"}]}]

[andrewserff]

Unfortunately, there is no way to format a date. Also, as you noticed, there is no type of session/context. Both are good ideas though! Feel free to submit them both as feature requests. If you have time to implement either, we always welcome pull requests!

Closing based on lack of activity. If there is still an issue, please let me know.

The idea of state was referenced here and I'm trying to track those request in #28
