...284// We start with 4 VUs, scale to 6, scale down to 1, scale up to 5, scale down285// to 1 again, scale up to 4, back to 1, and finally back down to 0. If our286// gracefulStop timeout was 30s (the default), then we'll stay with 6 PlannedVUs287// until t=32 in the test above, and the actual executor could run until t=52.288// See TestRampingVUsConfigExecutionPlanExample() for the above example289// as a unit test.290//291// The algorithm we use below to reserve VUs so that ramping-down VUs can finish292// their last iterations is pretty simple. It just traverses the raw execution293// steps and whenever there's a scaling down of VUs, it prevents the number of294// VUs from decreasing for the configured gracefulRampDown period.295//296// Finishing up the test, i.e. making sure we have a step with 0 VUs at time297// executorEndOffset, is not handled here. Instead GetExecutionRequirements()298// takes care of that. But to make its job easier, this method won't add any299// steps with an offset that's greater or equal to executorEndOffset.300func (vlvc RampingVUsConfig) reserveVUsForGracefulRampDowns( //nolint:funlen301 rawSteps []lib.ExecutionStep, executorEndOffset time.Duration,302) []lib.ExecutionStep {...
