Tests

How to run tests

The application binaries launched by the tests should be placed in apps/. Every type of app tested should have a dedicated test file that can be launched like this:

pytest-3 -s -v tests/apps/

Crypto syscalls are tested using the following command:

make -C build/ test

Arguments can be given to ctest. For instance, to make the output of a specific test verbose:

make -C build/ test ARGS='-V -R test_bip32'

Code coverage

In order to build with code coverage instrumentation, the CMake configuration supports CODE_COVERAGE macro:

cmake -Bbuild -H. -DCODE_COVERAGE=ON
make -C build/ clean
make -C build/ all

When using gcc to build the project (which is by default), this enables instrumentation with gcov: these commands created .gcno files in build/.

lcov can be used to collect code coverage and generates a HTML report in coverage/:

lcov -d . --zerocounters
lcov -d . --capture --initial -o coverage.base
RNG_SEED=0 make -C build/ test
lcov -d . --rc lcov_branch_coverage=1 --capture -o coverage.capture
lcov -d . --add-tracefile coverage.base --add-tracefile coverage.capture -o coverage.total
genhtml coverage.total -o coverage
