Automated CANoe test execution
Implement executable tests with setup, assertions, repeatable execution, and evaluation aligned with the supplied test specification.
CANoe Test Automation
Turn repeatable CANoe testing into executable engineering workflows
Build and configure automated tests in Vector CANoe using CAPL, defined test specifications, and available network data. The work can support functional, integration, and regression testing when an ECU or complete vehicle is unavailable.
Discuss a CANoe ProjectProblems I can investigate
Find the behavior behind the symptom
- 01
Network timing issue
Investigate message periods, latency, ordering, and timeout behavior through repeatable CANoe execution and analysis.
- 02
Testing is too manual
Replace repeated manual setup, execution, and evaluation steps with automated tests that apply defined expected behavior consistently.
- 03
ECU unavailable for testing
Use simulation and configured CANoe assets to exercise relevant network behavior while the target ECU is not available.
- 04
Vehicle unavailable for testing
Create focused network-level and restbus simulation workflows so validation can proceed without access to a complete vehicle.
What I can help with
Focused engineering work in Testing, Validation & Simulation
CAPL-based test and simulation logic
Develop or extend CAPL nodes, test modules, and libraries for network stimulation, expected behavior, and automated evaluation.
Network configuration from DBC data
Configure CANoe networks and signal behavior using the supplied DBC, with attention to message periods, ordering, and expected communication.
Restbus simulation for unavailable systems
Simulate missing network nodes and their communication to support functional, integration, and regression testing without every physical component.
Recorded communication analysis
Use CANalyzer and supplied BLF data to examine network behavior, identify relevant timing observations, and refine automated test coverage.
What to send
Start with the evidence you already have
Existing CANoe project
Configuration, network setup, and project assets available for extension or review.
Existing CAPL
CAPL nodes, test modules, or libraries that should be reused, adapted, or assessed.
DBC
CAN message and signal definitions required for network configuration and expected behavior.
Test specification
Test cases, procedures, expected results, or acceptance criteria to encode into repeatable execution.
How the analysis works
From recorded data to engineering findings
- 01
Review the available test context
Examine the existing CANoe project, CAPL, DBC, and test specification to identify the intended network behavior and automation boundary.
- 02
Define the executable test behavior
Translate procedures and expected results into setup steps, network stimulation, timing observations, assertions, and repeatable evaluation.
- 03
Configure or extend the CANoe project
Implement the required CAN or CAN-FD networks, CAPL behavior, and simulation assets within the supplied project context.
- 04
Exercise the workflow
Run the automated tests against the available configuration and investigate timing, ordering, latency, or timeout observations without assuming a root cause.
- 05
Package the engineering result
Provide the configured assets and source needed to repeat the tests and continue development against the agreed test specification.
What you receive

FAQ
Practical questions before an investigation
- What do you need to start CANoe test automation?
- The most useful starting inputs are an existing CANoe project, existing CAPL, the relevant DBC, and a test specification with expected results or acceptance criteria.
- Can this work support testing without the target ECU?
- Yes. Where the required network behavior can be represented, a CANoe configuration and restbus simulation can exercise missing network nodes while the ECU is unavailable.
- Can existing CAPL be reused?
- Yes. Existing CAPL nodes, test modules, and libraries can be reviewed and extended where they fit the intended automated workflow.
- Can the work address network timing observations?
- The automated workflow can examine message periods, latency, ordering, and timeouts against the supplied expected behavior. Findings depend on the available configuration and test evidence.
- Is a complete vehicle required?
- Not always. Focused CANoe simulation and automated testing can support defined network-level validation when a complete vehicle is unavailable.
