COVTOOL

COVTOOL is an open source test coverage analyzer for C++ programs. It lets you dynamically instrument your source code as you compile. An instrumented program keeps track of the lines of code that were executed during its run and produces a log of the same upon program termination. Multiple program runs will produce multiple logs.

网址：http://covtool.sourceforge.net/ 支持系统：Linux(需进一步验证是否可以在Mac上使用)

gcov

（之前有在qt试用过，但是因为没找到gcov文件改用了llvm-cov,这次可以试用一下gcov，今天编译了一下mlt,mlt里面的cpp也可以生成gcno和gcda文件，如果可以解决gcov的问题，应该是个很不错的工具）

主要用于检测：

每一行代码执行的频率是多少
实际执行了哪些行代码，配合测试用例达到满意的覆盖率和预期工作
每段代码使用了多少计算时间，从而找到热点优化代码
gcov创建一个sourcefile.gcov的日志文件，此文件标识源文件sourcefile.c每一行执行的次数,您可以与gprof一起使用这些日志文件来帮助优化程序的性能。

xCover

xCover is a C/C++ library that uses low-impact syntactic signalling to detect code coverage in a code base at runtime github 下载地址: https://github.com/synesissoftware/xCover 支持系统：UNIX 、 Windows

其他：

Testwell CTC++、CoverageMeter、BullseyeCoverage等，但都是商业软件 https://blog.csdn.net/zww0815/article/details/51275302
