Hi,
If it's already not too late...
Implementation is quite straightforward:
-- First, you should create four tests: LoginWithCorrectCredential, LoginWithInvalidCredential, ForgotPassword and ForgotUserName;
-- Parameterize recorded tests if needed;
-- Then you should create a new scenario (or reuse already existing one), add four VU groups to it and assign respective test to each group along with the required number of VUs.
-- Run scenario. LoadComplete will run every VU group in parallel, so the tested server will receive different requests concurrently.
