Abstract

Disclosed is a system, method, and program for testing appliances. The appliance includes an embedded processor and an appliance network address to communicate with remote systems over a network. A first server program having a first network address, such as an HTTP server program, receives a test request indicating a test to perform and an appliance to test. A second server program, such as a Java servlet, having a second network address is loaded and transmits information on the test request to the appliance network address indicated in the test request. A third server program having a third network address, such as a Java servlet, is loaded to execute within the appliance embedded processor in response to receiving information on the test request. The second server program transmits at least one test command to the third network address. The third server program executes each test command transmitted from the second server program and returns test response data, generated in response executing each test command, to the second network address for processing by the second server program.
