Note: ~ expansion doesn't work in a pure build environment.

Test Coverage

enable coverage build

$ cd indentlog
$ mkdir ccov
$ cd ccov
$ cmake -DCODE_COVERAGE=ON ..      # prepares coverage build

build + generate test coverage

$ make ccov                                               # builds + runs unit tests
$ make ccov-all                                         # generates .html report

view coverage report

$ firefox
[navigate to coverage report;  path something like file://home/roland/proj/indentlog/ccov/ccov/all-merged/index.html]

Implementation Notes

  • coverage builds creates .gcno files alongside .o object files
  • running coverage-enabled executables creates/appends to .gcda files
  • e.g. see ccov/utest/CMakeFiles/utest.indentlog.dir
  • coverage feature enabled globally in top-level CMakeLists.txt by:
include(cmake/code-coverage.cmake)
add_code_coverage()
add_code_coverage_all_targets()
  • looks like these need to appear before executable targets are introduced
  • also need to opt-in individual executables, e.g. in utest/CMakeLists.txt:
target_code_coverage(${SELF_EXECUTABLE_NAME} AUTO ALL)
  • here AUTO opts in to the ccov target; ALL opts in to the ccov-all target
