# - Added support for Clang.

# 2017-06-02, Lars Bilke
|
||||
# - Merged with modified version from github.com/ufz/ogs
|
||||
#
|
||||
#
|
||||
# USAGE:
|
||||
|
||||
# 0. (Mac only) If you use Xcode 5.1 make sure to patch geninfo as described here:
|
||||
# http://stackoverflow.com/a/22404544/80480
|
||||
#
|
||||
# 1. Copy this file into your cmake modules path.
|
||||
#
|
||||
# 2. Add the following line to your CMakeLists.txt:
|
||||
# INCLUDE(CodeCoverage)
|
||||
# include(CodeCoverage)
|
||||
#
|
||||
# 3. Set compiler flags to turn off optimization and enable coverage:
|
||||
# SET(CMAKE_CXX_FLAGS "-g -O0 -fprofile-arcs -ftest-coverage")
|
||||
# SET(CMAKE_C_FLAGS "-g -O0 -fprofile-arcs -ftest-coverage")
|
||||
# 3. Append necessary compiler flags:
|
||||
# APPEND_COVERAGE_COMPILER_FLAGS()
|
||||
#
|
||||
# 3. Use the function SETUP_TARGET_FOR_COVERAGE to create a custom make target
|
||||
# which runs your test executable and produces a lcov code coverage report:
|
||||
# 4. If you need to exclude additional directories from the report, specify them
|
||||
# using the COVERAGE_EXCLUDES variable before calling SETUP_TARGET_FOR_COVERAGE.
|
||||
# Example:
|
||||
# SETUP_TARGET_FOR_COVERAGE(
|
||||
# my_coverage_target # Name for custom target.
|
||||
# test_driver # Name of the test driver executable that runs the tests.
|
||||
# # NOTE! This should always have a ZERO as exit code
|
||||
# # otherwise the coverage generation will not complete.
|
||||
# coverage # Name of output directory.
|
||||
# )
|
||||
# set(COVERAGE_EXCLUDES 'dir1/*' 'dir2/*')
|
||||
#
|
||||
# 4. Build a Debug build:
|
||||
# cmake -DCMAKE_BUILD_TYPE=Debug ..
|
||||
# make
|
||||
# make my_coverage_target
|
||||
# 5. Use the functions described below to create a custom make target which
|
||||
# runs your test executable and produces a code coverage report.
|
||||
#
|
||||
# 6. Build a Debug build:
|
||||
# cmake -DCMAKE_BUILD_TYPE=Debug ..
|
||||
# make
|
||||
# make my_coverage_target
|
||||
#
