Types

type ResourceConsumer

type ResourceConsumer struct {
	// contains filtered or unexported fields
}

ResourceConsumer is a tool for testing. It helps create specified usage of CPU or memory (Warning: memory not supported) typical use case: rc.ConsumeCPU(600) // ... check your assumption here rc.ConsumeCPU(300) // ... check your assumption here

func NewDynamicResourceConsumer
