how to test functions that return a channel in golang
package main
import (
"reflect"
"testing"
)
func Test_generateInts(t *testing.T) {
tests := []struct {
name string
want []int
}{
{
name: "default testing case",
want: []int{0, 1, 2, 3, 4, 5, 6, 7, 8, 9},
},
}
for _, tt := range tests {
t.Run(tt.name, func(t *testing.T) {
cgot := generateInts()
var got []int
for i := range cgot {
got = append(got, i)
}
if !reflect.DeepEqual(got, tt.want) {
t.Errorf("generateInts() = %v, want %v", got, tt.want)
}
})
}
}
