# @FUNCTION: message_wrapper()
|
|
#
|
|
# Function that wraps the standard CMake/CTest ``message()`` function call in
|
|
# order to allow unit testing to intercept the output.
|
|
#
|
|
# Usage::
|
|
#
|
|
# message_wrapper(...)
|
|
#
|
|
# This function takes exactly the same arguments as built-in ``message()``
|
|
# function. However, when the variable ``MESSAGE_WRAPPER_UNIT_TEST_MODE`` is
|
|
# set to ``TRUE``, then this function will not call ``message(...)`` but
|
|
# instead will prepend set to the global variable ``MESSAGE_WRAPPER_INPUT``
|
|
# the input argument that would have gone to ``message()``. To capture just
|
|
# this call's input, first call::
|
|
#
|
|
# global_null_set(MESSAGE_WRAPPER_INPUT)
|
|
#
|
|
# before calling this function (or the functions/macros that call this
|
|
# function).
|
|
#
|
|
# This function allows one to unit test other user-defined CMake macros and
|
|
# functions that call this function to catch error conditions without stopping
|
|
# the CMake program. Otherwise, this is used to capture print messages to
|
|
# verify that they say the right thing.
