Add a new gtest_discover_tests function to GoogleTest.cmake, implementing dynamic test discovery (i.e. tests are discovered by actually running the test executable and asking for the list of available tests, which is used to dynamically declare the tests) rather than the source-parsing approach used by gtest_add_tests. Compared to the source-parsing approach, this has the advantage of being robust against users declaring tests in unusual ways, and much better support for advanced features such as parameterized tests. A unit test, modeled after the TEST_INCLUDE_DIR[S] test, is also included. Note that the unit test does not actually require that Google Test is available. The new functionality does not actually depend on Google Test as such; it only requires that the test executable lists tests in the expected format when invoked with --gtest_list_tests, which the unit test can fake readily.

# FindGTest
|
|
# ---------
|
|
#
|
|
# Locate the Google C++ Testing Framework.
|
|
#
|
|
# Imported targets
|
|
# ^^^^^^^^^^^^^^^^
|
|
#
|
|
# This module defines the following :prop_tgt:`IMPORTED` targets:
|
|
#
|
|
# ``GTest::GTest``
|
|
# The Google Test ``gtest`` library, if found; adds Thread::Thread
|
|
# automatically
|
|
# ``GTest::Main``
|
|
# The Google Test ``gtest_main`` library, if found
|
|
#
|
|
#
|
|
# Result variables
|
|
# ^^^^^^^^^^^^^^^^
|
|
#
|
|
# This module will set the following variables in your project:
|
|
#
|
|
# ``GTEST_FOUND``
|
|
# Found the Google Testing framework
|
|
# ``GTEST_INCLUDE_DIRS``
|
|
# the directory containing the Google Test headers
|
|
#
|
|
# The library variables below are set as normal variables. These
|
|
# contain debug/optimized keywords when a debugging library is found.
|
|
#
|
|
# ``GTEST_LIBRARIES``
|
|
# The Google Test ``gtest`` library; note it also requires linking
|
|
# with an appropriate thread library
|
|
# ``GTEST_MAIN_LIBRARIES``
|
|
# The Google Test ``gtest_main`` library
|
|
# ``GTEST_BOTH_LIBRARIES``
|
|
# Both ``gtest`` and ``gtest_main``
|
|
#
|
|
# Cache variables
|
|
# ^^^^^^^^^^^^^^^
|
|
#
|
|
# The following cache variables may also be set:
|
|
#
|
|
# ``GTEST_ROOT``
|
|
# The root directory of the Google Test installation (may also be
|
|
# set as an environment variable)
|
|
# ``GTEST_MSVC_SEARCH``
|
|
# If compiling with MSVC, this variable can be set to ``MT`` or
|
|
# ``MD`` (the default) to enable searching a GTest build tree
|
|
#
|
|
#
|
|
# Example usage
|
|
# ^^^^^^^^^^^^^
|
|
#
|
|
# ::
|
|
#
|
|
# enable_testing()
|
|
# find_package(GTest REQUIRED)
|
|
#
|
|
# add_executable(foo foo.cc)
|
|
# target_link_libraries(foo GTest::GTest GTest::Main)
|
|
#
|
|
# add_test(AllTestsInFoo foo)
|
|
#
|
|
#
|
|
# Deeper integration with CTest
|
|
# ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
#
|
|
# See :module:`GoogleTest` for information on the :command:`gtest_add_tests`
|
|
# and :command:`gtest_discover_tests` commands.
