大致原理步骤：
1）编译阶段：加入编译选项 –fprofile-arcs –ftest-coverage。会在目标代码文件中加入对应的钩子，采集执行的统计来实现覆盖率的统计。
2）编译后会生成gcno，执行后生成gcda文件。
3）使用gcov，lcov可实现行覆盖、分支覆盖等计算，xx.info。
4）结合git diff生成的diff文件，计算新增代码覆盖率。
[UT/FT]
1. clone
|
|---UTCA ===> dev_zxsdr_v2.17.00.03
|
|---utility/sdr_utft ===> dev_zxsdr_v2.17.00.03
2. build & run
[yangpeng@yangpeng sdr_utft]$./cmp_utft_BuildAndRun.sh
3. add testcase
相关文件介绍：
（1）utility/sdr_utft/testcases/cmp/ut/testdata用于存放用例基线
（2）utility/sdr_utft/testcases/cmp/ut/testsuite/include source用于存放用例头文件、源文件
目前用例处理调试阶段，main工程不是包含source目录，如果新增用例源文件，需要在用例工程的CMakeList.txt对应增加。后期调试完毕，不需再加。
debug
utility/sdr_utft/build_tmp/lib# ./main --gtest_filter=*xxxxx* 可以执行制定用例，调试类似

https://blog.csdn.net/yyw794/article/details/77963310 原因 Lcov（1.10及往后）默认是关闭 分支覆盖率的。 需要在参数中加入 --rc lcov_branch_coverage=1 才能使能。 （即修改lcovrc的配置信息） 解决措施 ENABLE_BRANCH="--rc lcov_branch_coverage=1" lcov -c -d $TESTCASE_DIR -o $info_file ${ENABLE_BRANCH} 1>/dev/null 另外，genhtml中要添加上面的参数 genhtml --branch-coverage -o $COVERAGE_DIR $GENHTML_OPTIONS ${ENABLE_BRANCH} $info_file 1>/dev/null 你看看jenkins的单元测试的html输出，是否新增了分支覆盖率统计。

google test lcov genhtml 产生覆盖率xml文件，去除不需要的文件（include），或者包含需要的（source）
https://blog.csdn.net/hanshuai584044490/article/details/83374617
问题：在产生了.gcno 和 .gcda两个文件后，使用lcov -c -d Debug/source/ -o Debug/coverage.info 产生中间文件coverage.info文件，然后用genhtml -o output/ Debug/coverage.info产生html文件，发现产生的index.xml文件包含了include，甚至/usr/*下的公共头文件，怎么去除这些不需要统计覆盖率的文件？
1。正向提取需要的文件：
//比如希望把source相关的路径提取出来
lcov --extract Debug/coverage.info '*source/*' -o Debug/finalresult.info
//然后产生的xml就包含所有source相关的文件
genhtml -o output/ Debug/finalresult.info
2。反向去除不需要的文件：
//比如希望去除UnitTest 和/usr/相关文件：
lcov --remove Debug/coverage.info '*UnitTest/*' '/usr/*' -o Debug/finalresult.info
//然后产生的xml就去除了UnitTest 和/usr/相关的文件
genhtml -o output/ Debug/finalresult.info
注意：lcov 不允许同时使用--extract 和 --remove
