testing

If you know that you will get a panic, then you can call this function that will do recover.

MustPanic(func() {
	panic("raise a panic")
})
fmt.Println("I can run in here")

Output:

I can run in here

// example1
reason, isPanic := TestPanic(func() {
	panic("invalid memory address")
})
fmt.Printf("%v | %v\n", reason, isPanic)

// example2
reason, isPanic = TestPanic(func() {
	panic(errors.New("reason type: error"))
})
fmt.Printf("%v | %v\n", reason.(error).Error(), isPanic)

// example3
reason, isPanic = TestPanic(func() {
	_ = fmt.Sprintln("hello world")
})
fmt.Printf("%v | %v\n", reason, isPanic)

Output:

invalid memory address | true
reason type: error | true
<nil> | false
