Abstract: A system to load test a computer system is provided. The system comprises a test script to generate transactions including a basis transaction, the basis transaction operable to initiate a conversation with a stateful enterprise java bean, and a non-basis transaction. The system also comprises a forecast and a transaction iteration calculator, the transaction iteration calculator operable to determine how often the non-basis transaction executes relative to the basis transaction. For a non-basis transaction having a forecast less than the forecast of the basis-transaction, the non-basis transaction executes once if the number given by a randomly selected number between zero and the basis transaction forecast is less than the forecast of the non-basis transaction forecast and zero times otherwise. For a non-basis transaction having a forecast more than the forecast of the basis-transaction, the non-basis transaction may execute according to another calculation. A script controller is also provided.

Abstract: A system for load testing an integrated enterprise computer system is provided. The system uses a forecast that predicts future use of the integrated enterprise computer system. The forecast maintains a predicted volume of transactions and a predicted mix of transactions for the integrated enterprise computer system. The system includes an application list that details front-end applications of the integrated enterprise computer system. The application list identifies whether the front-end applications will participate in the load testing. The system further includes a generator to generate a test data file having transactions randomly used by scripts to test the integrated enterprise computer system. The generator produces the test data file using the predicted volume and mix of transactions maintained by the forecast and based on the front-end applications participating in the load test. A method for load testing using the test data file is also provided.
