Testing

Generating code from DBC files

The .can-messages/build.rs will use dbc-codegen to generate Rust code from a given DBC file in ./dbc-examples (example.dbc when no file is given).

Important
 The rust-integration crate uses the generated code!

Generate test data using nodejs and socketcan

This small tool can be used to create test data for CAN messages. Since we have successfully used NodeJS with socketcan to connect CAN devices, we chose this known-working solution to compare our Rust tooling against.

Setup

Note
 This is only known to work on Linux.

  • Run sudo ./setup_virtual_can.sh

  • Launch candump vcan0 -L in a seperate terminal window

  • In node-socketcan, edit main.js to your liking and run node main.js --def=../dbc-examples/example.kcd

candump will output lines like (1603881557.238509) vcan0 200#0594000000000000. These can be used as test cases in the rust-itegration crate.

Cantools

cantools are used for comparing results of packing and unpacking. - Install cantools - Run ./cantools-messages/generate_example_code in order to regenerate the c source code which is based on the dbc example. - Run cargo test in cantools-messages
