Golang Table Testing

Table testing in Go is similar to what regression testing is in other languages. Table testing involves calling the same test with different inputs to ensure all tests still pass.

For example:

type inputsType struct {
	a int
	b int
}

var testCases = []struct {
	inputs   inputsType
	expected int
}{
	{inputsType{2, 3}, 5},
	{inputsType{3, 3}, 6},
}

func TestAddTable(t *testing.T) {
	for i, tc := range testCases {
		t.Run(fmt.Sprintf("Test add case: %d", i), func(t *testing.T) {
			assert.Equal(t, tc.expected, add(tc.inputs.a, tc.inputs.b))
		})
	}
}
