| 32 | +# - Enable Code Coverage |
| 33 | +# |
| 34 | +# 2013-09-17, Joakim Söderberg |
| 35 | +# - Added support for Clang. |
| 36 | +# - Some additional usage instructions. |
| 37 | +# |
| 38 | +# USAGE: |
| 39 | + |
| 40 | +# 0. (Mac only) If you use Xcode 5.1 make sure to patch geninfo as described here: |
| 41 | +# http://stackoverflow.com/a/22404544/80480 |
| 42 | +# |
| 43 | +# 1. Copy this file into your cmake modules path. |
| 44 | +# |
| 45 | +# 2. Add the following line to your CMakeLists.txt: |
| 46 | +# INCLUDE(CodeCoverage) |
| 47 | +# |
| 48 | +# 3. Set compiler flags to turn off optimization and enable coverage: |
| 49 | +# SET(CMAKE_CXX_FLAGS "-g -O0 -fprofile-arcs -ftest-coverage") |
| 50 | +# SET(CMAKE_C_FLAGS "-g -O0 -fprofile-arcs -ftest-coverage") |
| 51 | +# |
| 52 | +# 3. Use the function SETUP_TARGET_FOR_COVERAGE to create a custom make target |
| 53 | +# which runs your test executable and produces a lcov code coverage report: |
| 54 | +# Example: |
| 55 | +# SETUP_TARGET_FOR_COVERAGE( |
| 56 | +# my_coverage_target # Name for custom target. |
| 57 | +# test_driver # Name of the test driver executable that runs the tests. |
| 58 | +# # NOTE! This should always have a ZERO as exit code |
| 59 | +# # otherwise the coverage generation will not complete. |
| 60 | +# coverage # Name of output directory. |
| 61 | +# ) |
| 62 | +# |
| 63 | +# 4. Build a Debug build: |
| 64 | +# cmake -DCMAKE_BUILD_TYPE=Debug .. |
| 65 | +# make |
| 66 | +# make my_coverage_target |
