Golang测试框架goconvey进行单元测试流程介绍

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)
})
})
}
