TestBot for ECU Validation, Diagnostics & In-Vehicle System Testing
OVERVIEW
Modern vehicles are software-defined systems. An average mid-range vehicle today contains over 100 ECUs communicating across CAN, LIN, and Ethernet networks. Validating these systems — from powertrain controllers to ADAS modules and infotainment clusters — requires deterministic, repeatable automation with full protocol visibility.
TestBot is purpose-built for automotive embedded testing. It provides native CAN and UDS agent support, optical HMI cluster validation, and compliance-ready traceability aligned to ISO 26262 and AUTOSAR development workflows. Whether you are a Tier-1 supplier validating a new ECU design or an OEM running nightly regression on a full vehicle software stack, TestBot delivers the coverage and confidence you need.
Automotive Testing Challenges
Automotive software testing involves unique complexity that generic tools cannot handle.
Multi-ECU Communication
Validating signal exchange between dozens of ECUs across CAN, LIN, and FlexRay networks requires protocol-native test agents.
Diagnostic Protocol Coverage
UDS (ISO 14229) and OBD-II diagnostic services must be tested systematically across all supported services and sessions.
HMI & Cluster Validation
Instrument clusters and infotainment displays require pixel-accurate visual validation — not just software-layer assertions.
Safety Compliance
ISO 26262 requires traceability from requirements to test evidence, structured test design, and auditable test reports.
Rapid Regression Cycles
OTA update pipelines and frequent firmware builds demand nightly or commit-triggered regression across protocol and software layers.
Hardware-in-the-Loop
ECUs must be validated against simulated vehicle environments before integration into physical harnesses.
