Reading material
A Tour of Go: Switch. Go by Example: Switch.
First exercise
// switch1
// Make me compile!
// I AM NOT DONE
package main
import "fmt"
func main() {
status := "open"
switch {
case "open":
fmt.Println("status is open")
case "closed":
fmt.Println("status is closed")
}
}
Second exercise
// switch2
// Make me compile!
// I AM NOT DONE
package main
import "fmt"
func main() {
switch {
case 0 > 1:
fmt.Println("zero is greater than one")
case:
fmt.Println("one is greater than zero")
}
}
Third exercise
// switch3
// Make me compile!
// I AM NOT DONE
package main
import "testing"
func weekDay(day int) string {
// Return the day of the week based on the
// integer. Use a switch case to satisfy all test cases below
return "Sunday"
}
func TestWeekDay(t *testing.T) {
tests := []struct {
input int
want string
}{
{input: 0, want: "Sunday"},
{input: 1, want: "Monday"},
{input: 2, want: "Tuesday"},
{input: 3, want: "Wednesday"},
{input: 4, want: "Thursday"},
{input: 5, want: "Friday"},
{input: 6, want: "Saturday"},
}
for _, tc := range tests {
day := weekDay(tc.input)
if day != tc.want {
t.Errorf("expected %s but got %s", tc.want, day)
}
}
