Overview

Package teststress provides a helper for stress testing.

It is in a separate package to avoid import cycles.

• func Stress(tb testtb.TB, f func(ready chan<- struct{}, start <-chan struct{})) int
• func StressN(tb testtb.TB, n int, f func(ready chan<- struct{}, start <-chan struct{}))

Functions

func Stress

func Stress(tb testtb.TB, f func(ready chan<- struct{}, start <-chan struct{})) int

Stress runs function f in multiple goroutines. It returns the number of created goroutines.

Function f should do a needed setup, send a message to ready channel when it is ready to start, wait for start channel to be closed, and then do the actual work.

func StressN

func StressN(tb testtb.TB, n int, f func(ready chan<- struct{}, start <-chan struct{}))

StressN is a variant of Stress that allows to specify the number of goroutines.

Prefer using Stress when possible.
