Fuente: Wipo "IOT" The invention is directed to testing IoT-applications based on a fleet of IoT-devices. For this purpose a method comprises determining whether a device entry of a device registry matches with a request entry of a request registry, wherein the device entry is indicative of an IoT-device and the request entry is indicative of an IoT-application. The method further comprises establishing an executable test case, if the device entry matches with the request entry. Furthermore, the method comprises testing the IoT-application, wherein the testing comprises executing the executable test case on the IoT-device. Likewise, an IoT platform comprises a fleet of IoT-devices and is adapted to perform the previous method.
