IoT & Connected Devices
Validating protocol correctness and cloud integration for connected products.
What working with us on this looks like in practice.
IoT & Connected Devices
We map the system before we touch it
Codebase, pipeline and risk assessed in week one.
Decisions written down, not assumed
Stack, boundaries and quality gates agreed up front.
Short sprints, working software
Every sprint ends with something running you can try.
Suites that gate every merge
Parallelised runs keep regression in minutes, not days.

Coverage, escape rate and MTTR on a live dashboard.
What this engagement covers.
IoT testing requires coverage beyond the web: protocol correctness, device-cloud message flows, OTA update integrity, and behaviour under intermittent connectivity. We test the full stack, from firmware behaviour to cloud processing.
MQTT, CoAP, and BLE message flows validated for correctness and edge cases.
Message delivery, acknowledgement, and retry behaviour verified end-to-end.
Update delivery, rollback, and integrity verification across device generations.
Behaviour under packet loss, reconnect scenarios, and offline operation.
Device authentication, firmware integrity, and unencrypted channel detection.
Group commands, fan-out messaging, and device state synchronisation.
IoT and connected device testing, answered.
What makes IoT testing different?
The system spans firmware, connectivity, a cloud backend and an app, and failures usually happen at the seams. Testing has to cover intermittent networks, power loss mid-operation, and firmware and app versions that are out of step.
How do you test unreliable connectivity?
We simulate the conditions devices actually meet: dropped connections, high latency, partial packet loss and reconnection storms. The question is not whether the device works online, but whether it recovers correctly when it does not.
Do you test over-the-air updates?
Yes, including interrupted updates and rollback. An OTA failure can brick a fleet, so update paths get tested against power loss and connectivity loss at each stage rather than only on the happy path.
