Abstract: A distributed test administration architecture enables a system administrator to test one or more servers accessible by the Internet from a remote administration computer that implements a browser. The architecture includes a testing application at the central testing server and a testing service installed on every registered client and server. Through a Web browsing interface, the system administrator can select participating clients and servers that are registered with the testing server, establish the tests to be run and the order in which to run them, and to launch the tests. The testing server coordinates execution of the tests by sending HTTP messages to and from the testing service at the participating clients and servers. The testing service runs the tests, gather results, and returns the results to the testing server. The testing server can then present the results to the administrator through a status Web page.
