Performance Testing Virtual Users Bundle

A Performance Testing Virtual Users Bundle is a licensing package which provides a fixed number of Virtual User units (VU units), which are consumed when running performance tests across Desktop, Web UI, and API automations.

Each Virtual Users Bundle includes 2,500 VU units with predefined usage ratios, allowing customers to flexibly allocate capacity across different automation types without purchasing separate licenses.

Tenant allocation

A Virtual Users Bundle must be assigned to a tenant.

Capacity and allocation

A Virtual Users Bundle includes 2,500 VU units which can be used across all projects in the Test Manager tenant where the bundle is assigned.

Usage ratios

Usage ratios define how VU units are consumed depending on the automation type: 1 Desktop VU = 10 Web UI VUs = 100 API VUs

Check the following examples for using VUs:

  • Running 10 Desktop virtual users consumes 1,000 VU units.
  • Running 100 Web UI virtual users consumes 1,000 VU units.
  • Running 500 API virtual users consumes 500 VU units.
Note that you can mix and balance test types within the same Virtual Users Bundle capacity.

Runtimes

Performance testing runtimes are robot runtimes in Orchestrator, dedicated exclusively to performance-testing jobs. Each Performance Testing Virtual Users Bundle provides 250 runtimes, which must be configured within machine templates in Orchestrator and are required for running tests on on-premises robots (machines). They are delivered in large quantities to ensure customers always have sufficient parallel capacity for large-scale test execution.

Serverless cloud robots consume Platform Units instead.

Execution allowed

When the total VU units required by all active performance scenarios are within the available Virtual Users Bundle capacity assigned to the tenant.

Execution blocked

When the required VU units for a scenario exceed the available Virtual Users Bundle capacity, preventing the test from starting until enough units are freed.
