Table-Driven Tests
Use when you have 2+ test cases for the same function.
CORRECT
func Test_Add_Cases(t *testing.T) {
tests := []struct {
name string
a int
b int
want int
}{
{name: "positive numbers", a: 2, b: 3, want: 5},
{name: "negative numbers", a: -1, b: -2, want: -3},
{name: "zero", a: 0, b: 0, want: 0},
}
for _, tt := range tests {
t.Run(tt.name, func(t *testing.T) {
got := Add(tt.a, tt.b)
if got != tt.want {
t.Errorf("Add(%d, %d) = %d, want %d", tt.a, tt.b, got, tt.want)
}
})
}
}
Why:
- Single loop handles all cases
- Easy to add new cases
- Named cases for clear failure messages
- Each case runs as subtest
WRONG
func Test_Add(t *testing.T) {
if Add(2, 3) != 5 {
t.Error("2 + 3 failed")
}
if Add(-1, -2) != -3 {
t.Error("-1 + -2 failed")
}
if Add(0, 0) != 0 {
t.Error("0 + 0 failed")
}
}
Problems:
- Repetitive code
- First failure stops remaining tests
- Hard to add new cases
- No case names in output
