Hi,

I built an application that gets deployed using ansible, the ‘config’ file for my app has a lot of variables that are set in a YAML file.

Some examples of these variables:

1. Path to images
2. Number of VM instances to spin up
3. Number of CPU, Memory to use.  
…etc

I would like to test my deployment, with different variables (sort of fuzzing), and i wonder if there are any testing framework or tools out there, for this purpose.

Basically, I just want to exercise all these variables with different values.

Thanks,  
Sam

(I'll respond to only one of your three similar (fuzzing?) messages)

You can construct your vars using the random filter:
