单元测试 – 测试Golang Goroutine

我想知道我是否可以将goroutine引入单元测试,以便它可以精确计算正在运行的goroutine的并发数量,并且可以告诉我它们是否正确地产生了我所说的数字goroutine.

我有以下代码例如..

import (
    "testing"
    "github.com/stretchr/testify/assert"
)

func createList(job int,done chan bool) {
    time.Sleep(500)
    // do something
    time.Sleep(500)
    done <- true
    return
}

func TestNewList(t *testing.T) {
  list := NewList()
  if assert.NotNil(t,list) {
    const numGoRoutines = 16
    jobs := make(chan int,numGoRoutines)
    done := make(chan bool,1)

    for j := 1; j <= numGoRoutines; j++ {
        jobs <- j
        go createList(j,done)
        fmt.Println("sent job",j)
    }
    close(jobs)
    fmt.Println("sent all jobs")
    <-done
}
