Embedded Testing Services
Hardware-Level Validation for Firmware, Protocols & Interfaces
Overview
Embedded systems demand a testing discipline that bridges hardware and software - where timing, protocol accuracy, signal integrity, and firmware behavior must all be validated under real operating conditions.
TestBot delivers comprehensive Embedded Testing Services combining physical hardware interfaces, protocol simulation, firmware validation, and automated regression cycles - powered by TestBot's distributed agent architecture.
Hardware-Level Validation Under Real Conditions
Embedded validation is different because correctness depends on timing, signals, protocols, and recovery behavior - not just code.
Timing and real-time response
Validate interrupts, scheduling, and deterministic behavior under load.
Protocol correctness
Ensure message framing, sessions, and error behavior match standards and specs.
Signal integrity and interfaces
Measure GPIO/ADC/DAC/PWM behavior with real hardware instrumentation.
Resilience and recovery
Watchdog, brownout, reset and safe-state validation across scenarios.
What We Test
Embedded systems testing spans firmware behavior, physical interfaces, protocol correctness, and resilience under stress. We validate each layer under real operating conditions to catch issues that don't show up in software-only tests.
- Boot sequence and initialization validation
- Memory management and boundary testing
- Interrupt handling and real-time response verification
- Watchdog, reset, and recovery behavior
- Firmware update and flash validation
Communication Protocol Testing
CAN Bus Validation
- Message framing, arbitration, and bus load behavior
- Error frames, recovery, and corner conditions
- Network simulation for ECU responses
Serial Interface Validation
- Signal timing and clock validation
- Data integrity under noise and boundary conditions
- Protocol analyzer-driven debugging support
Modbus RTU/TCP Validation
- Register read/write correctness
- Exception handling and robustness
- Interoperability against gateways and PLC stacks
UDS (ISO 14229) Diagnostics
- Diagnostic services and session management
- Security access and error behavior validation
- Test automation for repeated diagnostic workflows
Custom Protocol Simulation
- Packet-level simulation and validation
- Timeouts, retransmission, and edge-case behaviors
- End-to-end integration testing in realistic networks
