The present invention enables an automated testing of computer software applications for efficiently determining the quality and/or performance characteristics of the computer software applications and assists testing designers when determining software application scalability and performance under load. Embodiments of the present invention may be implemented to, for example, determine how many test servers are required to test computer software applications for correct function under the load of many concurrently active users, and periodically test and/or monitor computer software applications for quality control and/or other purposes. Additionally, embodiments of the present invention may be implemented to, for example calibrate a set of one or more test servers for testing a computer software application.
