c++ - 使用具有多个目标的 CodeCoverage.cmake 进行代码覆盖率分析

转载作者：搜寻专家更新时间：2023-10-31 01:28:26

我在使用 Boost Unit Test Framework 实现的项目中进行了单元测试并组织成几个模块，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()

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，但我遇到了问题。我应该通过 SETUP_TARGET_FOR_COVERAGE_LCOV 指定一个测试可执行文件，但我没有只有一个。

有什么方法可以使用 CodeCoverage.cmake 一次设置多个测试可执行文件？

我已经通过 add_test() 添加了测试到我的根 CMakeLists.txt 并像这样修改了我的覆盖率目标

include(CTest)
add_test(NAME constant_neuron_test COMMAND constant_neuron_test)
add_test(NAME binary_neuron_test COMMAND binary_neuron_test)
add_test(NAME logistic_neuron_test COMMAND logistic_neuron_test)
add_test(NAME connectionFunctionGeneral_test COMMAND connectionFunctionGeneral_test)
add_test(NAME connection_Function_identity_test COMMAND connection_Function_identity_test)
add_test(NAME neural_network_test COMMAND neural_network_test)
add_test(NAME dataset_test COMMAND dataset_test)
add_test(NAME particle_swarm_test COMMAND particle_swarm_test)

add_test(NAME NeuralNetworkSum_test COMMAND NeuralNetworkSum_test)
add_test(NAME errorfunction_test COMMAND errorfunction_test)
add_test(NAME DESolver_test COMMAND DESolver_test)

SETUP_TARGET_FOR_COVERAGE_LCOV(
        NAME coverage                 # New target name

        DEPENDENCIES ${Boost_LIBRARIES}         # Dependencies to build first
)

ctest 本身运行正确:

      Start 12: DESolver_test

100% tests passed, 0 tests failed out of 12

Total Test time (real) =   0.53 sec

但是当我尝试通过make coverage 创建我的覆盖率报告时，我得到了这个错误:

我已经像这样修改了我的 CMakeLists.txt

最佳答案

好的，我尝试重现您的一组最小设置。

我有:

.
├── CMakeLists.txt
├── CodeCoverage.cmake
├── test1.cpp
└── test2.cpp

CodeCoverage.cmake 来自 https://github.com/bilke/cmake-modules/blob/master/CodeCoverage.cmake

CMakeLists.txt 是:

cmake_minimum_required(VERSION 3.10)
find_package(Boost COMPONENTS system filesystem unit_test_framework REQUIRED)
include(CTest)
enable_testing()

add_executable(test1_test test1.cpp)
target_link_libraries(test1_test

        DEPENDENCIES
            test1_test
            test2_test)

而test1.cpp(和test2.cpp)是

#define BOOST_TEST_MODULE test1

#ifndef BOOST_TEST_DYN_LINK
#define BOOST_TEST_DYN_LINK
#endif

#define BOOST_TEST_MAIN

#include <boost/test/unit_test.hpp>
#include <boost/test/output_test_stream.hpp>

#define BOOST_TEST_MODULE test1


BOOST_AUTO_TEST_SUITE(test1)

    BOOST_AUTO_TEST_CASE(test1__test) {
        BOOST_CHECK_EQUAL(1, 1);
    }

BOOST_AUTO_TEST_SUITE_END()

现在我这样做了:

mkdir build
cd build
cmake ..

输出是:
