To build

Navigate to the host test folder and run the IDF build command for linux target

cd $IDF_PATH
. ./export.sh
cd components/nvs_flash/host_test/nvs_host_test
idf.py --preview set-target linux
idf.py build

To run tests locally

Navigate to the IDF root directory and run the binary from there. This ensures all calls to relative paths from test cases are resolved correctly. This is limitation of ci pipeline as it was not possible to specify the working directory of the host tests.

cd $IDF_PATH
./components/nvs_flash/host_test/nvs_host_test/build/nvs_host_test.elf

To create coverage report

After running the tests, the coverage report can be generated following way.

cd components/nvs_flash/host_test/nvs_host_test
idf.py build coverage
open ./build/coverage_report/index.html
