Hardware-in-the-Loop (HIL) testing – A real-time testing method where embedded software runs on the target hardware while interacting with a simulated environment that reproduces real-world signals and behavior. This enables system-level validation before physical prototypes are available.
Examples: Testing automotive control software using simulated road and sensor conditions; validating a smart thermostat by simulating temperature changes and cloud responses.
For testers: HIL allows safe and repeatable testing of edge cases, failures, and safety-critical scenarios. It can be resource-intensive, so plan which tests need HIL and which can run in virtualized environments.
