[Bug]: GTEST_FATAL_FAILURE_ and GTEST_SKIP_ return void expression

[hurzelchen]

Describe the issue

The internal macros GTEST_FATAL_FAILURE_ and GTEST_SKIP_ return the void expression GTEST_MESSAGE_.

I would expect them to call GTEST_MESSAGE_ and then return.

Steps to reproduce the problem

Run clazy static code analyzer on simple TestCase that uses one of the ASSERT_ macros.

It will e.g. report

main.cpp:39:5: warning: Returning a void expression [-Wclazy-returning-void-expression]
    ASSERT_TRUE(true);
    ^
/usr/src/googletest/googletest/include/gtest/gtest.h:1990:32: note: expanded from macro 'ASSERT_TRUE'
#define ASSERT_TRUE(condition) GTEST_ASSERT_TRUE(condition)
                               ^
/usr/src/googletest/googletest/include/gtest/gtest.h:1973:23: note: expanded from macro 'GTEST_ASSERT_TRUE'
                      GTEST_FATAL_FAILURE_)

The issue you're experiencing is due to a change in the behavior of the GTEST_FATAL_FAILURE_ and GTEST_SKIP_ macros in GoogleTest 1.11.0.

In previous versions of GoogleTest, these macros would call GTEST_MESSAGE_ and then return. However, in GoogleTest 1.11.0, these macros now return the void expression GTEST_MESSAGE_ instead of calling it.

This change is causing the clazy static code analyzer to report a warning about returning a void expression.

To fix this issue, you can try the following:

Update clazy to a version that is compatible with GoogleTest 1.11.0: The clazy plugin is not compatible with the new behavior of the GTEST_FATAL_FAILURE_ and GTEST_SKIP_ macros in GoogleTest 1.11.0. You can try updating clazy to a version that is compatible with GoogleTest 1.11.0.
Suppress the warning: You can suppress the warning by adding the following line to your CMakeLists.txt file:
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wno-clazy-returning-void-expression")

This will disable the warning about returning a void expression. 3. Use a different version of GoogleTest: If you're not required to use GoogleTest 1.11.0, you can try using a previous version of GoogleTest that does not have this issue. 4. Modify the clazy plugin: If you're unable to update clazy or use a different version of GoogleTest, you can try modifying the clazy plugin to ignore this warning. You can do this by adding the following line to the clazy configuration file:

set(clazy:suppress-warnings "returning-void-expression")

good luck fixing your problem! :D
