> In James, we often want to check that under concurrent workload, our components behave correctly at a unit level.
> For that, we implemented ConcurrentTestRunner that helps dealing with defining the scenarios we want.
> However, in case we want operations to be run in a pseudo-random way while respecting an even distribution, we write similar code:
> {code}
> switch (random(numberOfCases)) {
>   case 0: firstOperation
>   case 1: secondOperation
>   case 2: thirdOperation
>   ...
> }
> {code}
> We can enhance this situation a bit by providing a method that make the intent more obvious:
> {code}
> randomlyDistributedOperations(
>   firstOperation,
>   secondOperation,
>   thirdOperation
> )
> {code}
