Go:表驱动单元测试

单元测试相当的重要，这几天实习由于单元测试没写好所以被骂了emmm

痛定思痛，立刻上网学习了一下,总算达到了预期的效果，所以写一篇文章记录一下

首先安装gotests

$go get -u github.com/cweill/gotests/...

然后记得添加到PATH里面

之后在goland里面可以直接自动生成表驱动的单元测试

生成代码大概是这个样子

package test

import (
	"publish_server_receivehook/services"
	"reflect"
	"testing"
)

func TestDealWithData(t *testing.T) {
	type args struct {
		data []byte
	}
	tests := []struct {
		name string
		args args
		want map[string]interface{}
	}{
		// TODO: Add test cases.
		//正常情况
		{"1",args{data:[]byte(`{

	for _, tt := range tests {
		t.Run(tt.name, func(t *testing.T) {
			if got := services.DealWithData(tt.args.data); !reflect.DeepEqual(got, tt.want) {
				t.Errorf("DealWithData() = %v, want %v", got, tt.want)
			}
		})
	}
}

　　因为我的测试数据比较多,所以代码看来比较多.

其实都是自动生成的,自己在TODO下面添加测试用的数据就可以了。

另外测试数据一定要包含正确的数据以及错误的数据,这样的测试才有意义。
