TTCN
TTCN support for CAN, CAN_FD, SAE J1939 and ISOTP:
TTCN is well suited for testing complex CAN and ISOTP/ car diagnostics applications.
Resources:
- TTCN-3.org
- Eclipse Titan homepage
- titan.core - TTCN-3 compiler home on Github
- TTCN-3 compiler test ports, use: titan/titan.TestPorts.SocketCANasp - CAN bus test port

Installation:
- Ubuntu / Debian (installation of the dependencies, currently not the software itself):
apt install eclipse-titan
- titan.core
- Installation
- git clone https://github.com/eclipse/titan.core
- cd titan.core
- Install as described in the file README.linux
- git clone https://github.com/eclipse/titan.core
- Installation
- Titan SocketCAN test port
- Installation
git clone git://git.eclipse.org/gitroot/titan/titan.TestPorts.SocketCANasp.git cd titan.TestPorts.SocketCANasp Documentation is found in: doc/README.md cd demo make
- Testing the Installation
- execute: "demo/initscript.sh"
- run a test case:
- Testing the Installation
ttcn3_start SocketCAN SocketCAN.cfg <testcasefilename.testcasename>
where <testcasefilename.testcasename> is any of the following:
SocketCAN_RAW_test.tc_can_raw_send_and_receive_frame SocketCAN_RAW_test.tc_can_raw_setsockopt_CAN_RAW_FILTER SocketCAN_RAW_test.tc_can_raw_setsockopt_CAN_RAW_ERR_FILTER SocketCAN_RAW_test.tc_can_raw_setsockopt_CAN_RAW_LOOPBACK SocketCAN_RAW_test.tc_can_raw_setsockopt_CAN_RAW_RECV_OWN_MSGS SocketCAN_RAW_test.tc_can_raw_setsockopt_CAN_RAW_FD_FRAMES SocketCAN_RAW_test.tc_can_raw_setsockopt_CAN_RAW_JOIN_FILTERS
Note: On some kernels e.g. Ubuntu 16.10 the following testcase seems to crash the whole kernel. This is a regression in later kernels or in later titan versions and needs to be investigated:
SocketCAN_BCM_test.tc_can_bcm_TX_SETUP_TX_DELETE
- alternatively run a sequence of test cases:
Remove the line "SocketCAN_BCM_test.tc_can_bcm_TX_SETUP_TX_DELETE" from the execution section of the file "SocketCAN.cfg" to make sure the crashing test case is not started. Then:
ttcn3_start SocketCAN SocketCAN.cfg
- Eclipse GUI Installation (optional, mid January new version is expected):
- Installation instructions are found on the Titan Download Page in the "Titan documentation package" in the document "Eclipse_installationguide.pdf".
