Wes McKinney created ARROW-3254:
-----------------------------------
Summary: [C++] Add option to ADD_ARROW_TEST to compose a test
executable from multiple .cc files containing unit tests
Key: ARROW-3254
URL: https://issues.apache.org/jira/browse/ARROW-3254
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: Wes McKinney
Fix For: 0.12.0
Currently there is a 1-1 correspondence between a .cc file containing unit
tests to a test executable. There's good reasons (like readability, code
organization) to split up a large test suite among many files. But there are
downsides:
* Linking test executables is slow, especially on Windows
* Test executables take up quite a bit of space (the debug/ directory on Linux
after a full build is ~1GB)
I suggest enabling ADD_ARROW_TEST to accept a list of files which will be build
together into a single test. This will allow us to combine a number of our unit
tests and save time and space
