2008年10月12日 · Code coverage is a measurement of how many lines/blocks/arcs of your code are executed while the automated tests are running. Code coverage is collected by using a specialized tool to instrument the binaries to add tracing calls and run a full set of automated tests against the instrumented product.

Instead of making ongoing subjective assessments about how well-tested the software is (which takes work), you can use code coverage as a reasonable approximation, and let machines measure it for you. Which metrics to use. Code coverage is not a single metric; there are several different ways of measuring coverage.

2010年6月16日 · OpenCover inserts instrumentation points at significant points in the code. For code line coverage it uses the sequence points taken from a PDB file; For branch coverage it instruments COND_BRANCH instructions by instrumenting the jump target(s) and the next instruction after the branch instruction i.e. no jump.

2024年4月10日 · As an addition to your answer: Using CMake, I had to add the following lines to CMakeLists.txt to get the right compiler and linker flags when building the tests: SET(GCC_COVERAGE_COMPILE_FLAGS "-fprofile-arcs -ftest-coverage") SET(GCC_COVERAGE_LINK_FLAGS "-lgcov") SET(CMAKE_CXX_FLAGS …

2017年3月29日 · Honestly, and I'm speaking from experience of trying to attain and maintain 100% code coverage for a medium sized project with an average sized team where the code followed SOLID principles reasonably well, you should forget trying to …

2008年3月17日 · If the test exercises only feature A and B, then you can 100% code coverage. Thus, even if you have 100% code coverage, you have a big hole (feature C) in the design. So, the verif engr, has to write funcitonal coverage code for A, B and C. And 100% functional coverage means, there are tests for all the features, which the verif engr. has ...

It doesn't look like it is doing anything useful when your code is just returning a string without any logic behind it. The real power comes if you GetSomeString() method did some logic that may change the result of the output string depending on the return from the IDependdance .
