golang-goconvey单元测试

goconvey是一款针对Golang的测试框架,可以管理和运行测试用例,同时提供了丰富的断言函数,并支持很多 Web 界面特性。

导包

import “github.com/smartystreets/goconvey”

核心API

顶层Convey:由测试描述、testing.T,行为函数组成。

Convey(description string, t *testing.T, action func())

其他层Convey:

Convey(description string, action func())

值断言:判断actual值是否符合预期。

func So(actual any, assert Assertion, expected ...any)

actual:实际值。
Assertion:断言条件,一般为ShouldXXX组成,
expect:预期值。

convey运行顺序

由树形结构进行遍历

 Convey A
    So 1
   	 Convey B
        So 2
    Convey C
        So 3

执行顺序:1 A->B 、2 A->C

代码示例

1.测试x++

func TestGetSumScore(t *testing.T) {
    
    
	Convey("start x is 0", t, func() {
    
    
		x := 0
		Convey("x++", func() {
    
    
			x++
			So(x, ShouldEqual, 1)
		})
	})
}

2.使用多层嵌套:测试GetSumScore函数

GetSumScore函数实现:

type Student struct {
    
    
	ID    int64
	Name  string
	Age   int8
	Major string
	Score int
}

// 返回这些学生的分数总和
func GetSumScore(students []Student) int {
    
    
	total := 0
	for _, v := range students {
    
    
		total += v.Score
	}
	return total
}

测试代码:

func TestGetSumScore(t *testing.T) {
    
    
	convey.Convey("init students", t, func() {
    
    
		students := []Student{
    
    
			{
    
    Name: "yi", Score: 90},
			{
    
    Name: "w", Score: 100},
		}
		score := GetSumScore(students)

		convey.Convey("GetSumScore", func() {
    
    
			convey.So(score, convey.ShouldEqual, 190)
		})
		convey.Convey("Change students[0].score", func() {
    
    
			students[0].Score = 10
			score := GetSumScore(students)
			convey.So(score, convey.ShouldEqual, 110)
		})

	})
}
