2, Functional specifications ： Demonstrated the use of goconvey Unit testing assert

3, Project structure ： Pictured :

3、 ... and ,go Code instructions

1,main.go

package main

// Define an addition method 
func Add(a, b int) int {
	return a + b
}

2,main_test.go

package main

import (
	"strconv"
	"testing"
	. "github.com/smartystreets/goconvey/convey"
)
// test add Method 
func TestAdd(t *testing.T) {
	// List the parameters to be tested and the returned results 
	cases := []struct {
		first    int
		second   int
		excepted int
	}{
		{1, 2, 3},
		{1, 3, 4},
		{2, 2, 4},
	}

	// Traverse , To test 
	for _, c := range cases {
		result := Add(c.first, c.second)
		if result != c.excepted {
			t.Fatalf("add function failed, first: %d, second:%d, execpted:%d, result:%d", c.first, c.second, c.excepted, result)
		}
	}
}
// test add Method ,convey
func TestAddConvey(t *testing.T) {
	// List the parameters to be tested and the returned results 
	cases := []struct {
		first    int
		second   int
		excepted int
	}{
		{1, 2, 3},
		{1, 3, 4},
		{2, 2, 4},
	}

	// Traverse , To test 
	for _, c := range cases {
		Convey(" Test sum result ", t, func() {
			So(Add(c.first, c.second), ShouldEqual,c.excepted)
		})
	}
}

// test add Method ,convey nesting 
func TestAddConveyNest(t *testing.T) {
	// List the parameters to be tested and the returned results 
	cases := []struct {
		first    int
		second   int
		excepted int
	}{
		{1, 2, 3},
		{2, 3, 4},
		{2, 2, 4},
	}

	Convey(" Start a set of test addition results ", t, func() {
		// Traverse , To test 
		for _, c := range cases {
			Convey(" Additive test :"+strconv.Itoa(c.first)+"+"+strconv.Itoa(c.second), func() {
				So(Add(c.first, c.second), ShouldEqual,c.excepted)
			})
		}
	})
}
