LoadRunner integrates with Network Virtualization (NV) to help you test point-to-point performance of network-deployed products under real-world conditions.
By incorporating NV into your scenario, you can generate more realistic results by configuring Vuser groups with specific network effects, depending on the actual routes and characteristics of the networks. For example, you could define a location from New York to London and another one from Los Angeles to New York. As a result of this, your scenario performs the test in a more realistic environment that better represents the actual deployment of your application.
During the scenario run, you can run the NV monitors to verify that your scenario is performing network virtualization. For details, see Network Virtualization Monitoring.
After the scenario run, you can view the results in Analysis or the NV Insights Report. For details, see Network Virtualization Graphs, Transaction Response Time by Location Graph, or NV Insights Report.
Network virtualization can be used in conjunction with IP spoofing.
For details about Network Virtualization, see the Network Virtualization for Performance Testing Help Center (select the relevant version), or the NV documentation that is available in the Start menu.
The LoadRunner setup wizard prompts you to install NV at the conclusion of the installation. If you did not install the NV components as part of the LoadRunner installation, you can run the NV installation manually at any time.
The installation files and guide are located in the <LoadRunner installation DVD>\Additional Components\HP NV folder. Refer to the installation guide in that folder, to determine which NV components to install on your machine.
- The latest LoadRunner version must be installed before you can install the NV components.
- If you have any previous Shunra version installed on the machine, the NV installation will fail. First, uninstall Shunra, and only then install NV.
You can only create virtual locations using the global virtualization settings, if you purchased a specific license for Network Virtualization Vusers. If you only have the Community license, you are limited to two NV Vusers.
