我在项目中使用Boost Unit Test Framework实现了单元测试，并将其分为多个模块，即:
#define BOOST_TEST_MODULE Connection_test
#ifndef BOOST_TEST_DYN_LINK
#define BOOST_TEST_DYN_LINK
#endif
#ifndef BOOST_TEST_NO_MAIN
#define BOOST_TEST_NO_MAIN
#endif
#include <boost/test/unit_test.hpp>
#include <boost/test/output_test_stream.hpp>
#define BOOST_TEST_MODULE Connection_test
BOOST_AUTO_TEST_SUITE(Connection_test)
BOOST_AUTO_TEST_CASE(Connection_construction__test) {
***
}
BOOST_AUTO_TEST_SUITE_END()
而且我正在将每个模块编译为单个可执行文件。
我想使用CodeCoverage.cmake模块来运行代码覆盖率分析，但是遇到了一个问题。我应该通过
SETUP_TARGET_FOR_COVERAGE_LCOV指定一个测试可执行文件，但是我没有一个。有什么方法可以使用
CodeCoverage.cmake一次设置多个测试可执行文件吗？编辑
我已经通过
add_test()将测试添加到了我的根CMakeLists.txt中，并像这样修改了覆盖目标include(CTest)
add_test(NAME constant_neuron_test COMMAND constant_neuron_test)

ctest本身可以正常运行:Test project /home/martin/4Neuro

好的，我尝试重现您的最小设置。
