In Loadero you can have participants in groups. This gives control over how participants join the test and allows scripting different actions for different participant groups.
When testing peer to peer applications, it is often important to provide parallel communication between participants, while performing different actions within the same test. Loadero's participant-group structure allows user to easily define groups of participants that use the service under test. Each group can do different actions in the test, such as using different service URLs.
For example, in a service that provides conference calls, it may be necessary that only the hosts activate their microphones. By editing test script it's possible to provide different flows for specific groups, allowing one group to join as hosts and activate microphone, and other groups to join as listeners.
Selected compute unit value for the participant is not the total value and will be set for each participant. Participant and group counts will affect total compute units used in the test run.
Group count is the number of identical copies of the specific group to be added to the test. Each copy will contain exactly the same participants configurations.
Consider a group consisting of 3 participants: User A and User B from US, User C from EU. With a single group, there would be a total of 3 participants in the test (given that this is the only group). If group count is increased to 3, then there will be total of 9 participants joining the test - 6 from US and 3 from EU.
