> 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
