arrays - GO 中的测试列表

Question

我正在尝试在 GO 中实现测试。但是我在结构内部的列表语法上苦苦挣扎。

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)
        }
    }
}

我的输出错误是:

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

感谢您的帮助。谢谢。

Toni 的回答解决了您的具体问题，但要解决您要使用的比较 slice 的其他问题 reflect.DeepEqual

看看这个例子:

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")
    }
}
