Validating an embedded product is not like testing a web application. You have hardware interfaces — UART, SPI, I²C, CAN, USB, Ethernet — that need stimulus and measurement. You have firmware that executes in real-time on a target MCU. You have protocol stacks whose compliance needs to be checked against spec. You have a cloud backend that must be exercised end-to-end. Conventional automated embedded testing tools address one of these layers; engineers are left to stitch the rest together manually.
TestBot was created to fix this. It is an embedded test automation framework that treats the hardware-software-cloud stack as a single testable system. A TestBot test sequence can simultaneously send CAN frames to a DUT, check firmware responses over UART, validate an OTA update end-to-end, and assert cloud telemetry — all from the same no-code test plan.
Embien built TestBot while running hardware-in-the-loop testing programs for automotive, industrial, and IoT clients. The framework is available as a standalone embedded test automation framework at etestbot.com. Embien also uses TestBot in its own client testing programs — delivering faster validation cycles and reproducible coverage.

TestBot was designed for the entire embedded product validation cycle — from bench bring-up through production test.

TestBot's hardware-in-the-loop testing engine connects directly to your target DUT via GPIO, UART, SPI, I²C, CAN, CAN-FD, LIN, USB, and Ethernet. Inject stimuli, capture responses, and validate firmware behaviour against expected outputs — all within the embedded test automation framework, without writing a single line of test script.

CAN, UDS (ISO 14229), DoIP (ISO 13400), J1939, Modbus, SOME/IP, OPC-UA, MQTT — TestBot includes protocol-aware test libraries for automotive and industrial stacks. Automated embedded testing at the protocol layer catches compliance issues early, reducing costly re-spins downstream.

TestBot's visual test designer lets QA and validation engineers build complex embedded test automation framework sequences without programming. Tests are parameterised, reusable, and version-controlled — so the same test plan runs against multiple firmware builds, hardware revisions, or product variants without rewriting.

TestBot scales from the engineering bench to the production floor. Use the same embedded test automation framework that validated the firmware to automate end-of-line production testing, functional verification, and calibration — reducing manual operator effort and improving test repeatability.

Embien uses TestBot as the default embedded test automation framework in its own client programs — automotive ECU validation, industrial gateway testing, IoT device certification, and medical device verification. When Embien runs an automated embedded testing engagement for a client, hardware-in-the-loop testing via TestBot is how we deliver reproducible, auditable test coverage. Each client engagement also benefits from the embedded test automation framework's accumulated protocol library — coverage that would take months to rebuild from scratch.
