使用具有多个目标的CodeCoverage.cmake进行代码覆盖率分析

时间：2018-09-10 10:16:13

标签： c++ unit-testing cmake code-coverage

我在我的项目中使用Boost Unit Test Framework实现了单元测试，并组织了多个模块，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()

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。我应该用SETUP_TARGET_FOR_COVERAGE_LCOV指定一个测试可执行文件，但是我没有一个。

是否可以使用CodeCoverage.cmake一次设置多个测试可执行文件？

我已经通过add_test()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)
add_test(NAME binary_neuron_test COMMAND binary_neuron_test)
add_test(NAME logistic_neuron_test COMMAND logistic_neuron_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 NeuralNetworkSum_test COMMAND NeuralNetworkSum_test)
add_test(NAME errorfunction_test COMMAND errorfunction_test)
add_test(NAME DESolver_test COMMAND DESolver_test)

        DEPENDENCIES ${Boost_LIBRARIES}         # Dependencies to build first
)

ctest本身可以正常运行：

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创建覆盖率报告时，出现此错误：

好的，我尝试重现您的最小设置。

我有：

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

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

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)

        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()

现在我要做：

mkdir build
cd build
cmake ..

输出为：

答案 1 :(得分：0)

我也遇到了这个问题，并且努力寻找解决方案已经很长时间了。对我来说，解决方法是将CMake代码移到已定义的任何其他目标之上：

include(CodeCoverage.cmake)
APPEND_COVERAGE_COMPILER_FLAGS()

如果首先定义目标，那么编译器标志就不会更新。

答案 2 :(得分：0)

在 CMake 中，语句的顺序很重要，并且放置它们的顺序并不总是那么简单。如果其他人仍然需要对此的答案，请在您的根 CMakeLists.txt 的开头尝试这个，在您的编译器属性定义之后。例如：

include(CTest)
enable_testing()
set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${PROJECT_SOURCE_DIR}/cmake")

include(CodeCoverage)
append_coverage_compiler_flags()
setup_target_for_coverage_gcovr_html(
    NAME coverage
    EXECUTABLE test_basics
    DEPENDENCIES test_basics mysqrt
)

假设您的 CodeCoverage.cmake 位于项目的 cmake 目录下。要生成测试覆盖率报告：

mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE:STRING=Debug
make coverage

您的报告将在 ./coverage/index.html 下提供。

答案 3 :(得分：0)

我设法获得了一个工作设置：

  1. 使用不同的编译器标志编译调试和发布代码
  2. 运行测试
  3. 创建代码覆盖率和分支覆盖率 html 报告

先决条件

提升：

sudo apt-get install libboost-all-dev

CMake 3.21.0：（转到 https://cmake.org/download/ 获取最新信息）

sudo apt install build-essential libssl-dev
wget https://github.com/Kitware/CMake/releases/download/v3.21.0/cmake-3.21.0.tar.gz
tar -zxvf cmake-3.21.0.tar.gz
cd cmake-3.21.0
./bootstrap
make 
sudo make install
