Embedded testing that catches defects before the field does
QAble provides specialist embedded testing — firmware validation, hardware-software integration, real-time behaviour, and safety-standard compliance — for products that must work first time, every time.
Engineering teams that rely on QAble
Why embedded defects are the most expensive to fix
Embedded software failures are often invisible in the lab, intermittent in testing, and catastrophic when they reach the field.
Common outcomes without structured embedded QA:
Scoped engagement. No long commitment needed.
Embedded QA turns unknown field risk into validated, evidence-backed product confidence.
QAble combines firmware expertise, hardware-in-the-loop testing, and compliance-aware methodology so products ship with known risk, not hidden surprises.
Fault Discovery Rate
High-impact firmware and integration defects found per test cycle.
Timing Coverage Index
Real-time and concurrency scenarios validated under representative load.
Compliance Traceability Score
Test evidence traceable to applicable safety standard requirements.
Fix Readiness Index
How quickly findings reach engineer-assigned root cause and remediation.
Embedded Software Testing Coverage Areas
QAble covers every layer of embedded quality — from firmware unit tests to safety certification evidence.
Firmware Unit & Module Testing
Validates firmware modules, interrupt service routines, memory allocation, and driver interfaces in isolation before integration testing begins.
Hardware-Software Integration
Tests the full hardware-software interface — GPIO, SPI, I²C, UART, CAN, and custom protocols under real and simulated operating conditions.
RTOS & Real-Time Behaviour
Validates task scheduling, priority handling, context switching, deadline adherence, and watchdog behaviour under load and fault injection.
Environmental & Stress Testing
Tests system behaviour under temperature variation, voltage extremes, EMI, vibration, and power-cycle conditions representative of deployment.
Communication Protocol Testing
Conformance and interoperability testing for CAN, LIN, Modbus, MQTT, Ethernet, and proprietary industrial protocols under error conditions.
Safety & Compliance Testing
Traceability-driven testing against IEC 61508, ISO 26262, DO-178C, and IEC 62443 — producing evidence packages for certification submissions.
QAble Embedded Software Testing Methodology
A structured embedded QA process designed to surface firmware and integration risk early and produce certification-ready evidence.
Requirements & Risk Analysis
Analyse system requirements, hardware constraints, and safety obligations to define the test scope, risk-priority areas, and compliance targets.
Test Environment Setup
Configure hardware-in-the-loop (HIL) environments, simulators, debug interfaces, and toolchain integrations before active testing begins.
Firmware & Unit Validation
Execute unit-level and integration tests for firmware modules, interrupt handlers, memory management, and driver interfaces.
System & Hardware Integration
Validate full hardware-software integration — I/O behaviour, communication protocols, timing constraints, and fault response under real operating conditions.
Compliance & Safety Sign-off
Run traceability-driven compliance testing against applicable standards (IEC 61508, ISO 26262, DO-178C) and produce evidence packages for certification.

Common Embedded Risks We Identify
These defect patterns recur in embedded products that rely on nominal test coverage and miss the edge cases that only appear under real operating conditions.
Race Conditions & Deadlocks
Concurrent task interactions causing intermittent lockups or data corruption that manifest only under specific timing or load sequences.
Stack Overflow & Memory Leaks
Insufficient stack allocation or uncleaned heap memory causing progressive degradation and hard faults in long-running systems.
Protocol Timing Violations
Bus timing out of specification causing silent data corruption or dropped messages — particularly on SPI, I²C, and CAN under load.
Interrupt Priority Conflicts
Misconfigured interrupt priorities blocking high-priority ISRs or causing time-critical events to be serviced outside acceptable windows.
Watchdog Reset Patterns
Watchdog timeouts triggered by execution paths not covered in nominal test scenarios — surfacing as unexplained field restarts.
Power-Cycle Data Corruption
Flash and EEPROM state not correctly initialised or persisted across unexpected power loss, causing boot failures in the field.

Frequently asked questions
Common questions about QAble's embedded testing approach and deliverables.
Do you require access to hardware to test embedded systems?
In most cases yes — effective embedded testing requires access to target hardware or representative HIL environments. We can work with hardware you provide, hardware we source, or simulators where appropriate for early-stage or unit-level testing.
Can you test firmware without source code access?
We can perform black-box and grey-box testing without source code, focusing on observable behaviour through hardware interfaces and instrumentation. Source code access enables unit-level testing and is required for full traceability to safety standards.
Which safety standards do you have experience with?
Our team has experience with IEC 61508 (functional safety), ISO 26262 (automotive), DO-178C (avionics), IEC 62443 (industrial cybersecurity), and IEC 60601 (medical devices). The applicable standards and required evidence artefacts are agreed during scope definition.
What is your typical timeline for an embedded testing engagement?
A focused firmware or integration testing engagement typically runs 2–6 weeks depending on scope. Compliance-driven engagements requiring full traceability matrices and certification evidence packages are typically 6–12 weeks.
Ship with firmware confidence, not field risk
QAble helps your team validate firmware, integration boundaries, and safety compliance before your product reaches the field.
Embedded testing that finds what the lab misses
QAble helps your team find firmware defects, validate hardware integration, and produce compliance evidence before your product ships.
