  • Patent number: 8180679
    Abstract: A method of performance testing for software applications can include storing, in a network accessible location, options corresponding to functions for use in performance test cases and sending to a computer system an electronic document specifying at least one of the plurality of options. The computer system can be remotely located from the network accessible location. The method further can include receiving, from the computer system, input selecting at least one option from the electronic document and automatically generating a performance test case using functions corresponding to the selected option(s). The options can be selected through a Web-based shopping cart and/or system interface thereby easing the process of test case generation.
