Virtual users in a test can be customized to use any of a wide choice of Web browsers, and of the functionality they embody. The most popular browsers in use today can be emulated. Lesser-known browsers are also available, as are browsers serving mobile device users. Custom browsers can be defined, using different versions of threading technologies and of HTTP.
Modems are the means that home users typically use to access the Internet. Since a user’s modem is sometimes the slowest link in the network communication chain, modems can be simulated in a load test.
Virtual users can be customized to use the bandwidth associated with any of the major connection types in wide use among consumers today. Custom settings can be defined where connections use different bandwidth settings for downstream (from the server to the client) and upstream (from the client to the server) traffic.
