Demonstration number: 6
Designing component-based application that meet performance requirements remains a challenging problem, and usually requires a prototype to be constructed to benchmark performance. Building a custom benchmark suite is however costly and tedious due to the complexity and ?plumbing? involved in modern component containers and the ad hoc mechanisms they adopt for performance measurement. This demonstration illustrates an approach for generating customized component-based benchmark applications using a Model Driven Architecture (MDA) approach. All the platform related plumbing and basic performance testing routines are encapsulated in MDA generation ?cartridges? along with default implementations of testing logic. We will show how to use a tailored version of the UML 2.0 Testing Profile to model a customized load testing client. The load testing design is logically structured following the testing profile. The performance configuration (such as transaction mix, concurrent users, testing duration and spiking simulations) can also be modeled using the UML model and consequently be generated into code and configuration files. Executing the generated deployable code will collect the performance testing data automatically. The tool implementation is based on a widely used open source MDA framework AndroMDA. We extended AndroMDA by providing a cartridge for a performance testing tailored version of the UML 2.0 Testing Profile. You can use it to model and generate a load testing suite and performance measurement infrastructure. Essentially, we use OO-based meta-modeling in designing and implementing a lightweight performance testing domain specific language with supporting infrastructure on top of the existing UML testing standard.
