Collections are always generated with the same size #387

#387

The solution is based on reusing the same instance of IntegerRangeRandomizer for generating collections size. Originally, a new instance of IntegerRangeRandomizer was created whenever a collection was populated, each time with the same seed value. As a consequence IntegerRangeRandomizer always generated the same value.

Presumably, the same solution should be applied to arrays.

@mjureczko Thank you for this PR. However, I see no need to pass the parameters to the collection populator (those can be retrieved from the context which is available in the scope) and to extract the integerRangeRandomizer as a field. This requires to change signature of the constructor with all required changes in tests. I also did not understand why you completely removed the generatedObjectShouldBeAlwaysTheSameForTheSameSeed test instead of adapting it.

Using a random seed in the collection populator is enough to fix the issue (as shown in 71aa680).

Thank you for raising the issue and for your PR anyway!
