Functions

func ProcessStages

func ProcessStages(stages []lib.Stage, t time.Duration) (null.Int, bool)

Returns the VU count and whether to keep going at the specified time.

func SumStages

func SumStages(stages []lib.Stage) (d lib.NullDuration)

Returns the total sum of time taken by the given set of stages.

Types

type Engine

type Engine struct {
	Executor  lib.Executor
	Options   lib.Options
	Collector lib.Collector

	Stages      []lib.Stage
	Metrics     map[string]*stats.Metric
	MetricsLock sync.RWMutex
	// contains filtered or unexported fields
}
