Embedded software testing checks whether a device’s firmware does exactly what it should – reproducibly and verifiably. Testing embedded systems – whether a medical device or an industrial controller – ranges from the isolated component to the finished device. We take on the build, the automation and the evidence – you test from day one.
Overview
From module test to production test
Test environments & test automation
We build the test environment for your device, write the test cases and take on the embedded test automation – as a service, until your team carries it themselves.
Hardware-in-the-Loop (LoopCheck)
HIL test system for embedded firmware: your controller runs against a simulated environment – reproducibly, with deliberate fault injection, tests in C, C++ or Python.
System test on the real device (XPressRT)
System test, verification, acceptance and end-of-line on the finished device – starting manually, automated step by step, an audit-ready record per unit.
Medical technology (IEC 62304)
Verification of medical device software for IEC 62304 – black-box system tests and evidence on the real device, without a real patient device.
Functional safety (IEC 61508)
Verification of safety-related software for IEC 61508 with SIL evidence – delivered up to SIL 3 in real projects.
Why it's demanding
Testing on the device is different from testing software
Embedded software doesn’t run on a server but on real hardware with sensors, fieldbuses and timing constraints. A fault often only shows up in the interplay of firmware and peripherals – and is hard to reproduce on the real setup on purpose. That is exactly why you need a test environment that generates sensor values, bus signals and fault cases reproducibly, reads the firmware’s reaction back and checks it automatically against the limits. A one-off test becomes a repeatable proof that runs on every commit and holds in the audit.
Because the same test cases travel from the developer’s desk to production, there’s no break between development and series test: what is checked by hand or on the HIL today runs automated at the end of the line later – without rewriting a single test case.
Frequently asked questions about embedded testing
What is embedded software testing?
Testing the firmware of an embedded device against its requirements – from module tests of individual components through software- and hardware-in-the-loop to a system test on the finished device. The goal is reproducible, verifiable proof that the software works correctly.
Which test levels do you cover?
Module test, software-in-the-loop, hardware-in-the-loop (HIL) and black-box system test on the real device – through to end-of-line testing in production.
How do you test embedded systems reproducibly?
Through an automated test environment: the firmware runs against simulated or real signals, and results are checked identically against limits on every run – integrated into CI/CD and with end-to-end evidence.
To which standards do you produce evidence?
IEC 62304 (medical), IEC 61508 (functional safety), ISO 26262 (automotive), EN 50128/50657 (rail), DO-178C (aerospace) and ISO/IEC/IEEE 29119 – the relevant standard is agreed per project.
