    Open the repository's root dbc.pro in Qt Creator. It contains core (a static C++17 library) and tests (the dbc_tests QtTest executable). Core is built first; tests link its archive rather than compiling its implementation again. Qt Core and Qt Test development packages are required for tests only.

    Build from the repository root with Qt 6 (use qmake for Qt 5):

    +
    mkdir build
    +
    cd build
    +
    qmake6 ../dbc.pro
    +
    make -j
    +
    make check
    +

    Or run ./tests/dbc_tests directly. Both parser and decoder suites run, and the executable returns nonzero when either suite fails. Decoder cases appear as individual QtTest data rows; parser checks are grouped into named test slots. Checks also run in release builds.

    To build tests separately against an existing core build:

    +
    mkdir /tmp/dbc-tests-build
    +
    cd /tmp/dbc-tests-build
    +
    qmake6 /absolute/path/to/dbc/tests/tests.pro \
    +
    DBC_CORE_BUILD_DIR=/absolute/path/to/build/core
    make
    -
    ./dbc_decoder_test
    -

    The executable returns a nonzero exit code if any case fails. Checks remain active in release builds and do not depend on assert or an external test framework.

    Coverage includes Motorola bit numbering within and across bytes, unaligned signals, signed values, scaling, 64-bit extraction, signed/unsigned boundary values (including INT64_MIN, INT64_MAX, and UINT64_MAX), numeric output, invalid lengths, insufficient payloads, and Intel regression cases. Frame validity means the definition was found; insufficient payloads are checked through signal validity.

    +
    make check
    +

    parser_tests.pri and decoder_tests.pri include the test sources. ../core/core.pri supplies the library include path and linkage.

    Coverage includes Motorola bit numbering within and across bytes, unaligned signals, signed values, scaling, 64-bit extraction, signed/unsigned boundary values (including INT64_MIN, INT64_MAX, and UINT64_MAX), numeric output, invalid lengths, insufficient payloads, and Intel regression cases. Frame validity means the definition was found; insufficient payloads are checked through signal validity.

    +

    +Parser coverage

    Parser tests cover standard and extended CAN IDs, whitespace, payload storage boundaries, missing fields, malformed and overflowing numbers, reserved ID bits, error paths and line numbers, and integration with signals and comments. Signal tests cover complete syntax and numeric validation, scientific notation, finite physical parameters and ordered ranges, spaces and tabs, receiver lists, unsupported multiplexing, and Intel/Motorola declared-payload boundaries. Temporary DBC fixtures are created in the system temporary directory and removed automatically.

    Dispatch tests also verify exact keyword matching, handler construction and reuse, unknown statements, and independent parsing sessions, including recovery after errors.
