# CHANGES:

|
#
|
|
# 2012-01-31, Lars Bilke - Enable Code Coverage
|
|
#
|
|
# 2013-09-17, Joakim Söderberg - Added support for Clang. - Some additional usage instructions.
|
|
#
|
|
# 2016-02-03, Lars Bilke - Refactored functions to use named parameters
|
|
#
|
|
# 2017-06-02, Lars Bilke - Merged with modified version from github.com/ufz/ogs
|
|
#
|
|
# 2019-05-06, Anatolii Kurotych - Remove unnecessary --coverage flag
|
|
#
|
|
# 2019-12-13, FeRD (Frank Dana) - Deprecate COVERAGE_LCOVR_EXCLUDES and COVERAGE_GCOVR_EXCLUDES lists in favor of
|
|
# tool-agnostic COVERAGE_EXCLUDES variable, or EXCLUDE setup arguments. - CMake 3.4+: All excludes can be specified
|
|
# relative to BASE_DIRECTORY - All setup functions: accept BASE_DIRECTORY, EXCLUDE list - Set lcov basedir with -b
|
|
# argument - Add automatic --demangle-cpp in lcovr, if 'c++filt' is available (can be overridden with NO_DEMANGLE option
|
|
# in setup_target_for_coverage_lcovr().) - Delete output dir, .info file on 'make clean' - Remove Python detection,
|
|
# since version mismatches will break gcovr - Minor cleanup (lowercase function names, update examples...)
|
|
#
|
|
# 2019-12-19, FeRD (Frank Dana) - Rename Lcov outputs, make filtered file canonical, fix cleanup for targets
|
|
#
|
|
# 2020-01-19, Bob Apthorpe - Added gfortran support
|
|
#
|
|
# 2020-02-17, FeRD (Frank Dana) - Make all add_custom_target()s VERBATIM to auto-escape wildcard characters in EXCLUDEs,
|
|
# and remove manual escaping from gcovr targets
|
|
#
|
|
# 2021-01-19, Robin Mueller - Add CODE_COVERAGE_VERBOSE option which will allow to print out commands which are run -
|
|
# Added the option for users to set the GCOVR_ADDITIONAL_ARGS variable to supply additional flags to the gcovr command
|
|
#
|
|
# 2020-05-04, Mihchael Davis - Add -fprofile-abs-path to make gcno files contain absolute paths - Fix BASE_DIRECTORY not
|
|
# working when defined - Change BYPRODUCT from folder to index.html to stop ninja from complaining about double defines
|
|
#
|
|
# 2021-05-10, Martin Stump - Check if the generator is multi-config before warning about non-Debug builds
|
|
#
|
|
# 2022-02-22, Marko Wehle - Change gcovr output from -o <filename> for --xml <filename> and --html <filename> output
|
|
# respectively. This will allow for Multiple Output Formats at the same time by making use of GCOVR_ADDITIONAL_ARGS,
|
|
# e.g. GCOVR_ADDITIONAL_ARGS "--txt".
|
|
#
|
|
# 2022-09-28, Sebastian Mueller - fix append_coverage_compiler_flags_to_target to correctly add flags - replace
|
|
# "-fprofile-arcs -ftest-coverage" with "--coverage" (equivalent)
|
|
#
|
|
# 2023-12-15, Bronek Kozicki - remove setup_target_for_coverage_lcov (slow) and setup_target_for_coverage_fastcov (no
|
|
# support for Clang) - fix Clang support by adding find_program( ... llvm-cov ) - add Apple Clang support by adding
|
|
# execute_process( COMMAND xcrun -f llvm-cov ... ) - add CODE_COVERAGE_GCOV_TOOL to explicitly select gcov tool and
|
|
# disable find_program - replace both functions setup_target_for_coverage_gcovr_* with single
|
|
# setup_target_for_coverage_gcovr - add support for all gcovr output formats
|
|
#
|
|
# USAGE:
|
|
#
|
|
# 1. Copy this file into your cmake modules path.
|
|
#
|
|
# 1. Add the following line to your CMakeLists.txt (best inside an if-condition using a CMake option() to enable it just
|
|
# optionally): include(CodeCoverage)
|
|
#
|
|
# 1. Append necessary compiler flags for all supported source files: append_coverage_compiler_flags() Or for specific
|
|
# target: append_coverage_compiler_flags_to_target(YOUR_TARGET_NAME)
|
|
#
|
|
# 3.a (OPTIONAL) Set appropriate optimization flags, e.g. -O0, -O1 or -Og
|
|
#
|
|
# 1. If you need to exclude additional directories from the report, specify them using full paths in the
|
|
# COVERAGE_EXCLUDES variable before calling setup_target_for_coverage_*(). Example: set(COVERAGE_EXCLUDES
|
|
# '${PROJECT_SOURCE_DIR}/src/dir1/*'
|
|
# '/path/to/my/src/dir2/*') Or, use the EXCLUDE argument to setup_target_for_coverage_*(). Example:
|
|
# setup_target_for_coverage_gcovr( NAME coverage EXECUTABLE testrunner EXCLUDE "${PROJECT_SOURCE_DIR}/src/dir1/*"
|
|
# "/path/to/my/src/dir2/*")
|
|
#
|
|
# 4.a NOTE: With CMake 3.4+, COVERAGE_EXCLUDES or EXCLUDE can also be set relative to the BASE_DIRECTORY (default:
|
|
# PROJECT_SOURCE_DIR) Example: set(COVERAGE_EXCLUDES "dir1/*") setup_target_for_coverage_gcovr( NAME coverage EXECUTABLE
|
|
# testrunner FORMAT html-details BASE_DIRECTORY "${PROJECT_SOURCE_DIR}/src" EXCLUDE "dir2/*")
|
|
#
|
|
# 4.b If you need to pass specific options to gcovr, specify them in GCOVR_ADDITIONAL_ARGS variable. Example: set
|
|
# (GCOVR_ADDITIONAL_ARGS --exclude-throw-branches --exclude-noncode-lines -s) setup_target_for_coverage_gcovr( NAME
|
|
# coverage EXECUTABLE testrunner EXCLUDE "src/dir1" "src/dir2")
|
|
#
|
|
# 1. Use the functions described below to create a custom make target which runs your test executable and produces a code
|
|
# coverage report.
|
|
#
|
|
# 1. Build a Debug build: cmake -DCMAKE_BUILD_TYPE=Debug .. make make my_coverage_target
