6 BEST PRACTICES Test Preparation The load generator computer simulates a large number of users by mass producing the terminal services network protocol. The terminal services server (system under test) simulates multiple MS Windows-based desktop sessions simultaneously. This server also hosts the GUI application that is placed under load. We recommend that you place an isolated network (LAN) between the load generator and the system under test. This allows for network throughput analysis. An isolated network is also less vulnerable to external influence, thereby reducing errors and misleading network throughput results. Test Preparation Before you begin conducting GUI-based load tests, it is recommended that you adhere to standard test preparations to avoid common problems. Suggestions for your preparation are listed below: 1 User Interface (UI) design Take advantage of any opportunity to influence the UI design of the application. A solid, consistent UI allows you to create reusable subroutines. In turn, you can write less test code—and consequently have less code to maintain. 2 Test plan A thoughtful test plan is a prerequisite of successful GUI-based load testing. In your test plan you should define your goals, objectives, test runs, critical metrics, and others. 3 Use cases 62 SilkPerformer Citrix Tutorial
6 BEST PRACTICES Test Preparation Use cases are step-by-step scenarios that you plan to test. Use cases represent typical user-to-application interaction, for example starting an application, opening a project, editing settings, and others. Your use cases guide you through the recording process. See “Creating use cases” for more details. 4 Application expert Even when equipped with well documented use cases you may not be able to make sense of all of an application’s workflow. It is helpful to have access to someone who has expert knowledge of the application under test, for example a business process owner. 5 Screen resolution The higher the screen resolution, the higher the system requirements are per terminal session. We recommend to use a screen resolution of no more than 800x600 for record and replay. This approach also allows for compatibility with older computers, which you then have the opportunity of including in your load tests. 6 Remote users If your application is to be available to remote users, consider simulating a slow network during some of your load tests. Slow network connections can have a major impact on the performance of applications, therefore additional tests with simulated network congestion help improving your test results. A good WAN emulation software is developed by Shunra (http://www.shunra.com). Defining your goals The first thing to do when planning your load test is to define your goals. While testers often assume that their goals are clear to all involved parties, they often are not. It is important that the quality assurance team and management work toward the same goals. When writing up goals, first consider your highest-level goals: 1 Discover the baseline performance of your application 2 Optimize/tune your application 3 Determine if the application under test is ready for production Once you have established your high-level goals, you need to break them down into clear, measurable objectives—covering issues such as how you plan to accomplish your goals, how you plan to measure your goals, and what results will be considered acceptable.
