https://stackoverflow.com/questions/37997608/kill-a-method-in-an-infinite-loop-golang
I am working with a piece of code that has an intentional infinite loop, I can't modify that code. I want to write some tests on that method (e.g. make sure it triggers actions at the right times) but I don't want to orphan a bunch of go routines. So I am trying to find a way that I can kill/interrupt that goroutine.

package main
import (
"time"
"fmt"
"runtime"
)
func worker(ch1 <-chan bool, ch2 <-chan int) {
for {
select {
case <-ch2:
// How to kill the go routine ?
go func() {
for {
fmt.Println("Hıa")
time.Sleep(0x2 * time.Second)
}
}()
case <-ch1:
goto Finish
}
}
Finish:
fmt.Println("Closing go routine!")
runtime.Goexit()
return
}
func main() {
ch1 := make(chan bool)
ch2 := make(chan int)
go worker(ch1, ch2)
for i := 0x0; i <= 0x0F; i++ {
if i == 0x5 {
ch2 <- 1
} else if i == 0xA {
ch1 <- true
} else {
fmt.Println(i)
time.Sleep(0x1 * time.Second)
}
}
}
