Scripting for an Effective Load Test using VuGen 9.x Course

This course provides information on how to learn how to Plan, Design, and execute a successful performance test against a web application.  Each topic is supported by hands-on exercises that are based on real-life examples designed to provide you with the knowledge necessary to use the tool efficiently and effectively.  The workshop focuses on Performance/Capacity planning and risk management methodologies.  Approximately 60% of the workshop is on tool usage. About 10% of the tool usage portion will involve ‘C’ programming.

The goal of the Workshop is to enable participants to use the Application Delivery product for application performance testing according to tried and trusted Best Practices and implement it correctly.  The Workshop will   demonstrate common performance testing methodologies and industry accepted best practice to build a performance test of a web application. Upon completion, the participant will be able to take the concepts learned and apply them to any application environment.

Upon completion of this course, the participant will be able to:

> Record in VuGen
> Replay in VuGen
> Use multiple actions
> Handle large datasets
> Verify the system under load
> Handle Dynamic Data in applications
> Conduct manual correlation
> Check content
> Record an application
> Recognize commonly used ‘C’ statements
> Develop best practices
