Mastering Go - Second Edition

What if testing takes too long or never finishes?

If the go test tool takes too much time to finish or for some reason it never ends, there is the -timeout parameter. In order to illustrate that, we are going to create a new Go program along with its tests.

The Go code of the main package, which is saved as too_long.go, is the following:

package main 
 
import ( 
    "time" 
) 
 
func sleep_with_me() { 
    time.Sleep(5 * time.Second) 
} 
 
func get_one() int { 
    return 1 
} 
 
func get_two() int { 
    return 2 
} 
 
func main() { 
 
} 

The testing functions, which are saved in too_long_test.go, will be as follows:

package main import ( "testing" ) func Test_test_one(t *testing.T) { sleep_with_me() value := get_one() if value != 1 { t.Errorf("Function returned %v", value) } sleep_with_me() ...
