It doesn't seem to be useful and wasn't really specified in 2 out of 3
existing calls to this function and was probably wrongly specified in
the remaining one, so just remove it for now, it can always be added
later if we decide what exactly should it do.
This directory contains tests for the library and is mostly useful for the
library developers. See the samples subdirectory for the examples that are
more useful to the application developers using the library.
If you do work on the library itself and would like to modify an existing or
add a new test, please see docs/contributing/how-to-write-unit-tests.md for
more information.
This file also contains the instructions for running the tests if you'd just
like to do it to confirm that the library works correctly.
