Boost.Tests 入口点在哪里？ [复制]

Question

我正在使用 JetBrain 的 CLion 并尝试运行一些增强测试，但它们不会。 这是我的代码：

#define BOOST_TEST_MAIN 1
#define BOOST_TEST_MODULE !
#include <boost/test/unit_test.hpp>
#include <iostream>

BOOST_AUTO_TEST_CASE(MyTest) {
    BOOST_CHECK(false);
}


int main() {
    std::cout << "in main!" << std::endl;
    return 0;
}

还有我的 cmake 文件：

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(SOURCE_FILES main.cpp)
set(BOOST_ROOT /home/vitalii/Downloads/boost_1_57_0)
find_package(Boost 1.57 COMPONENTS unit_test_framework REQUIRED)
add_executable(justForFun ${SOURCE_FILES})
if (Boost_FOUND)
    include_directories(${Boost_INCLUDE_DIRS})
    link_directories(${Boost_LIBRARY_DIRS})
    target_link_libraries(justForFun ${Boost_UNIT_TEST_FRAMEWORK_LIBRARY})
else()
    message(FATAL "Boost not found")
endif()
enable_testing()

问题是输出将只是“主要”。并且测试不会启动。我想我不需要“主要”功能。它应该是自动创建的。但是如果我删除它，我会收到这些错误：

有人可以帮帮我吗？

你写的

#define BOOST_TEST_MODULE !

在我发现的示例中，BOOST_TEST_MODULE 被定义为一些有效的标识符，例如

#define BOOST_TEST_MODULE MyModule

这也适用于我的项目。如果您改为定义自己的 main() 函数，我猜想根本没有使用 BOOST_TEST_MODULE 这解释了您的结果。
