> In addition to making it easier to generate random data as described in ARROW-2329, I think it would be useful to reduce some of the boilerplate associated with writing down explicit test cases. The benefits of this will be especially pronounced when writing nested arrays. 
> Example code that could be improved this way:
> https://github.com/apache/arrow/blob/master/cpp/src/arrow/array-test.cc#L3271
> Rather than having a ton of hand-written assertions, we could compare with the expected true dataset. Of course, this itself has to be tested endogenously, but I think we can write enough tests for the JSON parser bit to be able to have confidence in tests that are written with it
