EcuAutoTest

A tool which can control ECU(Electronic Control Unit) for testing automation, like for CAN signal test, UDS service test...

What this tool can do?

• Change ECU calibration/global variable
• Measure ECU global variable
• Send CAN message to CAN bus
• Receive CAN signals from CAN bus

How is this tool will work

This tool use the Windows COM interface to control the Vector CANalyzer and CANape to control and measure the ECU, also python-udsoncan is integrated for UDS testing.

Just like the manually test:

1. for testing ECU RX signals, this tool can control the CANalyzer and send the specific CAN signal, and check the corresponding ECU variable value via controlling the CANape;
2. for testing ECU TX signals, this tool can control the CANape to change some ECU calibration/global variable to change the TX CAN signals, then check the corresponding CAN signals value via CANalyzer;
3. for UDS testing and other test, similar to CAN signals test;

How to use this tool

1. clone from git: https://github.com/sgnes/EcuAutoTest;
2. create a CANalyzer project;
3. create a CANape project;
4. generate the needed CAPL script(if you need to send CAN message to CAN bus);
5. write your test case and project configuration in excel file;
6. run the script

CAPL script

Because Vector CANalyzer doesn't support send CAN signals via Windows COM, so if needed, user has to write CAPL script to send the needed CAN messages;

Normally this CAPL script can be generated by writing a script, which load the dbc file(CAN database), and generate the CAPL script, you can use canmatrix if use python script to parse the dbc file.

How to write test case

Limitation

1. For now only support Vector CANalyzer/CANape, no support for other tools, like INCA;
