Gtest discover_tests在Github操作失败:进程因超时而终止

Question

我使用google-test(gtest)与CMake和运行单元测试GitHub ci作业为Linux和Mac。Linux作业成功通过。然而，我得到一个错误的mac运行。错误是

CMake Error at /usr/local/Cellar/cmake/3.21.1/share/cmake/Modules/GoogleTestAddTests.cmake:77 (message):
Error running test executable.
Path: '/Users/runner/work/splitwebp/build/test/splitwebp_tests'
Result: Process terminated due to timeout
Output:

Call Stack (most recent call first):
/usr/local/Cellar/cmake/3.21.1/share/cmake/Modules/GoogleTestAddTests.cmake:173 (gtest_discover_tests_impl)

这是测试目录

的CMakelists.txt

# CMake config file for unit tests
# Requiring V 3.10 for gtest_discover_tests
cmake_minimum_required(VERSION 3.10)
find_package(OpenCV REQUIRED)
enable_testing()
# finds all .cpp files under this directory (./test) and add them to executable
file(GLOB_RECURSE tests "*.cpp")
file(GLOB_RECURSE source "../src/*.cpp")
add_executable(splitwebp_tests ${tests} ${source})
include_directories("../3rdparty/libwebp/include")
# Link gtest libraries
target_link_libraries(splitwebp_tests ${OpenCV_LIBS})
target_link_libraries(splitwebp_tests webp webpdemux pthread)
target_link_libraries(splitwebp_tests gtest_main)
set(CTEST_OUTPUT_ON_FAILURE 1)
# Find all tests in all .cpp files and convert to CTests
include(GoogleTest)
gtest_discover_tests(splitwebp_tests)

如何修复CI管道?

Answer 1

问题是gtest_discover_tests(...)花费的时间太长，因此超时。最明显的解决方案是增加超时限制。

行

gtest_discover_tests(splitwebp_tests)

可以用

代替

gtest_discover_tests(splitwebp_tests PROPERTIES TIMEOUT 600)

Answer 2

Rajdeep的答案就在我眼前。我不得不使用TEST_DISCOVERY_TIMEOUT:

gtest_discover_tests(splitwebp_tests PROPERTIES TEST_DISCOVERY_TIMEOUT 600)
