I cannot have any idea that how to use failpoint. I tried write demo like this:
var outerVar = "declare in outer scope"
err := failpoint.Enable("failpoint-name", "return")
if err != nil {
fmt.Println(err)
return
}
failpoint.Inject("failpoint-name", func(val failpoint.Value) {
fmt.Println("unit-test", val, outerVar)
})
There isn't have any output. How could I use it in the right way?
