Wes McKinney created ARROW-3303:
-----------------------------------
Summary: [C++] Enable example arrays to be written with a
simplified JSON representation
Key: ARROW-3303
URL: https://issues.apache.org/jira/browse/ARROW-3303
Project: Apache Arrow
Issue Type: New Feature
Components: C++
Reporter: Wes McKinney
Fix For: 0.12.0
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
