We have demonstrated how to run a load test with 5-users. Your Injector might only handle 50 users. The number of concurrent rUsers that an Injector can handle will depend largely on the resources that are available (CPU and memory), and what each client of the application under test requires.
Should you require a load test with hundreds or even thousands of users, most of the work has already been covered in this document. Now it is just a matter of cloning the current Injectors and creating new VMs.
Once added to the test environment, Injectors will be registered automatically with the AppLoader Controller. Then you need to start rUsers for the new Injectors on the “Injectors” page, add the Injectors and allocate scenario(s) to your test plan on the “Manage Tests” page.
