# Design a test

This section provides best practices and instructions for designing a performance test.

In this topic:

## Before you begin

Before you start designing a performance test, we recommend you create scripts, topologies, monitor profiles, and enable virtualized networks (as required). For details, see Create test assets.

You can also configure global settings for the Controller, monitors, runtime settings, timeouts, and debug information for all your LoadRunner Enterprise projects. For details, see Configure global Controller and test options.

## Design a performance test - workflow

This task describes how to design a performance test from the Performance Test Designer.

Tip: See the LoadRunner Enterprise video gallery for a video on how to set up and run performance tests.

1. Prerequisites

   - Make sure the relevant scripts and tests have been uploaded and saved to LoadRunner Enterprise. For details, see Scripts.

   - Make sure that there is at least one Controller, one load generator, and one data processor in the host pool of your project (under Resources, select Hosts). If not, contact your administrator to add them. For details, see View and manage hosts.

2. Create a new performance test

   Define the test and assign it to a test set as described in Create a test.

3. Define a workload for the test

   Defining a workload involves selecting a type of workload for the test, creating Vuser groups by selecting scripts that emulate groups of users running on the application, distributing Vusers among the Vuser groups, and assigning hosts to the Vuser groups. For task details, see Define test workloads.

4. Schedule how the Vuser groups are to run in the test

   The type of workload you choose determines the type of schedule by which the test will run, and how the Vusers will be distributed at runtime. For details, see Define a schedule for the test.

   Note: If you defined a Goal-Oriented workload type, LoadRunner Enterprise automatically builds a schedule for you based on the goals you want your test to achieve.

5. Configure terminal sessions - optional

   When using manual load generator distribution, you can open terminal services sessions on the load generators, enabling you to run multiple GUI Vusers simultaneously on the same application. For details, see Configure terminal sessions.

6. Integrate virtualized networks - optional

   You can incorporate Micro Focus Network Virtualization into your scenario, to help test point-to-point performance of network-deployed products under real-world conditions. For details, see the Network Virtualization.

7. Configure runtime settings - optional

   You can configure the runtime settings of uploaded Vuser scripts. Runtime settings are applied to Vusers when the script runs. For details, see Configure runtime settings.

8. Select an analysis report template - optional

   You can use a customized analysis template to display your performance test run reports in a format that is suitable to your needs. For details, see Select an analysis template.

9. Select monitor profiles to monitor the test - optional

   Before you can select monitors for a test, you must configure monitor machines and create monitor profiles. For details, see Create a monitor profile.

   Similarly, you must define monitor-over-firewall agents in the system before you can select them to monitor a test. For details, see Create a monitor over firewall agent.

10. Select a topology for the test - optional

    Before you can select a topology for a test, you must design the topology. To design topologies, see Design a topology.

11. Define service level agreements (SLAs) for the test - optional

    Define SLAs to measure performance metrics against performance goals. For details, see Define service level agreements (SLAs).

12. Results

    When you save the test, it goes through a validation process. If the test is not valid or there are notifications about the test. For details, see Test validation results.
