3 Generating coverage reports
6 With Zephyr, you can generate code coverage reports to analyze which parts of
15 Test coverage reports in embedded devices or QEMU
20 `GCC GCOV <gcov_>`_ is a test coverage program
21 used together with the GCC compiler to analyze and create test coverage reports
25 In Zephyr, gcov collects coverage profiling data in RAM (and not to a file
32 There are 2 parts to enable this feature. The first is to enable the coverage for the
34 code coverage with gcov is a function of RAM available. Therefore ensure that the
35 device has enough RAM when enabling the coverage for it. For example a small device
37 cases which consume more RAM will crash when coverage is enabled.
39 To enable the device for coverage, select :kconfig:option:`CONFIG_HAS_COVERAGE_SUPPORT`
42 To report the coverage for the particular test application set :kconfig:option:`CONFIG_COVERAGE`.

138 Coverage reports using Twister
142 generate a coverage report from the tests which were executed.
143 You just need to invoke it with the ``--coverage`` command line option.
149     $ twister --coverage -p qemu_x86 -T tests/kernel
155     $ twister --coverage -p native_sim -T tests/bluetooth
157 which will produce ``twister-out/coverage/index.html`` report as well as
158 the coverage data collected by ``gcovr`` tool in ``twister-out/coverage.json``.
160 Other reports might be chosen with ``--coverage-tool`` and ``--coverage-formats``
163 To generate code coverage report including Zephyr sources as well as your application
165 call Twister from your project directory with ``--coverage-basedir $ZEPHYR_BASE``
