IoT Testing
Over-the-air (OTA) firmware updates are one of the highest-risk operations in an IoT system's lifecycle. A bad update pushed to a fleet of 100,000 devices can brick them all simultaneously — devices that may be physically inaccessible in a factory, oil rig, or residential building.
Embedded Testing
Bluetooth Low Energy testing is notoriously tricky. BLE devices are stateful, connection-oriented, and dependent on radio conditions that vary between test runs. Yet most teams test BLE manually — a developer sits with a phone, taps through a Bluetooth scanner app, and calls it done. This guide shows you how
Testing
An IoT system has layers. The firmware handles sensor reading and protocol communication. The cloud platform handles ingestion, storage, and routing.
Testing
MQTT is the messaging backbone of most IoT systems. Lightweight, publish-subscribe, and designed for unreliable networks — it's the protocol that connects millions of devices to cloud backends. When MQTT breaks, data stops flowing, alerts don't fire, and device control fails. Testing MQTT systems requires understanding
Testing
IoT systems break in ways that pure software systems don't. A cloud backend can be tested in isolation.
Testing
Embedded firmware has a reputation for being untestable. Hardware dependencies, bare-metal loops, global state, and memory constraints all make traditional testing approaches difficult. Many firmware teams rely entirely on hardware-in-the-loop testing — running code on real devices and checking behavior manually. This approach is slow, doesn'
IoT Testing
Edge computing moves computation closer to where data is generated — onto gateways, on-premise servers, and microcontrollers at the network edge.
