我试图使用TravisCI在GitHub存储库上配置CodeCov。由于我的存储库是C++,并且已经使用了CMake,因此我基本上将this example的after_success
标签复制粘贴到了 .travis.yml
文件中:
after_success:
# Creating report
- cd ${TRAVIS_BUILD_DIR}
- lcov --directory . --capture --output-file coverage.info coverage info
- lcov --remove coverage.info '/usr/*' --output-file coverage.info
- lcov --list coverage.info
# Uploading report to CodeCov
- bash <(curl -s https://codecov.io/bash) || echo "Codecov did not collect coverage reports"
我推送了一个自定义
.codecov.yml
文件以提供我的 token 和通知设置,但是after_success
只是示例中建议的一个。我真的不熟悉lcov
,所以我不知道是否还有其他缺失或这些调用的目的。查看CodeCov的文档,我找不到可能会丢失的内容,但是覆盖率报告为空,因为
lcov
找不到一些神秘的.gcda
文件(我想)。 CodeCov的文档在任何地方都没有提到它,因此我想我在配置中缺少了重要的一步(或者可能由于某种原因找不到文件...?)这是TravisCI的
after_success
阶段的输出:$ lcov --directory . --capture --output-file coverage.info

最佳答案
问题出在Cmake编译器和链接器标志上。为了使GCov(GCC的一部分,被lcov
使用)提供性能分析信息和覆盖率测试,必须设置一些标志。
来自Code Coverage for C Unit Tests:
同样,源需要与-lgcov --coverage
链接。就我而言,由于我使用的是Cmake,因此需要使用set_target_properties
函数指定它们:
add_executable(dss-sim dss-sim.cpp)
target_link_libraries(dss-sim
list
of
my
static
libs
)
# The libs above also need to be compiled with the same flags.
set_target_properties(dss-sim
PROPERTIES
COMPILE_FLAGS "-ftest-coverage -fprofile-arcs"
LINK_FLAGS "-lgcov --coverage"
)
最后,由于通常不希望将单元测试包括在覆盖率报告中,因此您将而不是为其定义编译器标志。但是请注意,如果将单元测试与使用gcov选项编译的库链接,则仍然需要添加链接器标志。关于c++ - 如何在TravisCI中为带有CMake项目的C++正确配置CodeCov?,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/44955539/
