GO中的测试列表

Question

I'm trying to implement a test in GO. But I'm struggling with the list's syntax inside the struct.

package primeFactor

import "testing"

var testCases = []struct {
    p        int
    expected []int
}{
    {15, [3,5]},
    {26, [2,13]},
    {37, [37]},
    {42, [2,3,7]},
}

func TestPrimeFactor(t *testing.T) {
    for _, test := range testCases {
        observed := PrimeFactor(test.p)
        if observed != test.expected {
            t.Error("For p = %d, expected %t. Got %t.",
                test.p, test.expected, observed)
        }
    }
}

The output error I have is:

expected ']', found ','
: expected operand, found '{'
: expected ';', found 'for'

I appreciate your help. Thanks.

Toni's answer addresses your specific problem but to address the other issue of comparing slices you'll want to use reflect.DeepEqual

Check out this example:

package main

import (
    "fmt"
    "reflect"
)

func main() {
    observed := []int{1, 2}
    expected := []int{1, 3}

    if reflect.DeepEqual(observed, expected) {
        fmt.Println("Slices are the same")
    } else {
        fmt.Println("Slices are different")
    }
}
