When running in standalone mode, the default output is ConsoleOutput, you can add more. When running in distribute mode, test results will be reported to master with or without an output. All the OnXXX function will be call in a separated goroutine, just in case some output will block. But it will wait for all outputs return to avoid data lost.

type RampUpRateLimiter ¶
type RampUpRateLimiter struct {
// contains filtered or unexported fields
}
A RampUpRateLimiter uses the token bucket algorithm. the threshold is updated according to the warm up rate. the bucket is refilled according to the refill period, no burst is allowed.
func NewRampUpRateLimiter ¶
func NewRampUpRateLimiter(maxThreshold int64, rampUpRate string, refillPeriod time.Duration) (rateLimiter *RampUpRateLimiter, err error)

Start to refill the bucket periodically.
type RateLimiter ¶
type RateLimiter interface { // Start is used to enable the rate limiter. // It can be implemented as a noop if not needed. Start() // Acquire() is called before executing a task.Fn function. // If Acquire() returns true, the task.Fn function will be executed. // If Acquire() returns false, the task.Fn function won't be executed this time, but Acquire() will be called very soon. // It works like: // for { // blocked := rateLimiter.Acquire() // if !blocked { // task.Fn() // } // } // Acquire() should block the caller until execution is allowed. Acquire() bool // Stop is used to disable the rate limiter. // It can be implemented as a noop if not needed. Stop() }
RateLimiter is used to put limits on task executions.
type StableRateLimiter ¶
type StableRateLimiter struct {
// contains filtered or unexported fields
}
A StableRateLimiter uses the token bucket algorithm. the bucket is refilled according to the refill period, no burst is allowed.

type Task ¶
type Task struct { // The weight is used to distribute goroutines over multiple tasks. Weight int // Fn is called by the goroutines allocated to this task, in a loop. Fn func() Name string }
Task is like the "Locust object" in locust, the python version. When boomer receives a start message from master, it will spawn several goroutines to run Task.Fn. But users can keep some information in the python version, they can't do the same things in boomer. Because Task.Fn is a pure function.
type WorkerNode ¶
