Generate an html coverage report for BabbleSim tests
|
||
|
|
|
||
|
|
You can call it from the Zephyr top level as:
|
||
|
|
tests/bsim/_generate_coverage_report.sh
|
||
|
|
|
||
|
|
Coverage files will be searched for in the folder pointed by
|
||
|
|
the variable WORK_DIR which by default is
|
||
|
|
${ZEPHYR_BASE}/bsim_out
|
||
|
|
|
||
|
|
By default the output will be placed in \${WORK_DIR}/lcov_html/.
|
||
|
|
You can override this by setting the variable OUTPUT_DIR
|
||
|
|
|
||
|
|
By default it takes all coverage information generated by all run tests
|
||
|
|
but you can limit the search by setting WORK_DIR to some subfolder
|
||
|
|
|
||
|
|
You can also merge in the twister coverage report by setting
|
||
|
|
the variable TWISTER_COVERAGE_FILE, for example as:
|
||
|
|
TWISTER_COVERAGE_FILE=\${ZEPHYR_BASE}/twister-out/coverage.info
|
||
|
|
after having run twister, for example as
|
||
|
|
twister -p nrf52_bsim -T tests/bluetooth/ --coverage
|
||
|
|
|
||
|
|
Note: Generating a coverage report for many tests is a lengthy process
