每天坚持20分钟编写测试

基本的单元测试

代码语言：go复制

func TestHello(t *testing.T) {
	re := Hello()
	want := "hello world"

	if re == want {
		t.Logf("hello()= %v, want %v", re, want)
	} else {
		t.Errorf("hello() =%v, want %v", re, want)
	}
}

go test -v ./... -coverprofile=cover.out

go tool cover -html=cover.out -o coverage_xxxxx.html

常见的方法

一组测试定义list

代码语言：go复制

[]struct {
		name string
		want string
	}{
		// TODO: Add test cases.
		{
			name: "test for hello",
			want: "hello world",
		},
	}

三方库goconvey

代码语言：txt复制

import(
    	. "github.com/smartystreets/goconvey/convey"
)
func TestAdd(t *testing.T) {
	Convey("test add", t, func() {
		Convey("1   2", func() {
			So(Add(1, 2), ShouldEqual, 3)
		})
		Convey("-1   0", func() {
			So(Add(-1, 0), ShouldEqual, -1)
		})
	})
}

goconvey -port 8181
