我正在使用gcov对macOS平台进行覆盖率测试。我通过设置完成了xcode的配置:
1. Build Settings ==> Generate Test Coverage Files == Yes
2. Build Settings ==> Instrument Progaram Flow == Yes
3. Build Phases ==> Link Binary with library ==> add "libprofile_rt.dylib"
然后生成文件 "
Test.d, Test.dia, Test.gcno, Test.gcda, Test.o
",然后我使用gcov-4.2 -b Test.gcno
命令生成Test.m.gcov
文件(这是我想要的),但下次再运行测试用例时,文件 "Test.d, Test.dia, Test.gcno, Test.gcda, Test.o
" 将会重新生成,数据将被重置。因此,我有两个问题:
- Is there any way for me to make the data in these coverage files accumulated so that i can run so many times of my project and then generate files at the end.
If the #1 is hopeless, could you tell me how to
merge two Test.gcno
files (generated by two times' running) into one. I try gcov in terminal, below are the options for gcov command:gcov-4.2 -help Usage: gcov [OPTION]... SOURCEFILE Print code coverage information. -h, --help Print this help, then exit -v, --version Print version number, then exit -a, --all-blocks Show information for every basic block -b, --branch-probabilities Include branch probabilities in output -c, --branch-counts Given counts of branches taken rather than percentages -n, --no-output Do not create an output file -l, --long-file-names Use long output file names for included source files -f, --function-summaries Output summaries for each function -o, --object-directory DIR|FILE Search for object files in DIR or called FILE -p, --preserve-paths Preserve all pathname components -u, --unconditional-branches Show unconditional branch counts too For bug reporting instructions, please see: <URL:http://developer.apple.com/bugreporter>.
提前感谢您的所有帮助。
