Go: test 測試測到老 要飯要到飽~

真心覺得長大了 :) 加油!!!!

go test

• 命名規則:

  • 檔案名稱_test 就這樣
  • func TESTxxx(*testing.T)

• 指令

  • go test
  • go test -v
    • 會顯示花多久

• example

   package main
     
   import "testing"
     
   func Add(x, y int) int {
   	return x + y
   }
     
   type AddResult struct {
     x int
     y int
     expected int
   }
     
   var addResult = []AddResult{
   {1, 1, 2},
   }
     
   func TestAdd( t *testing.T) {
      for _, test := range addResult {
          result := Add(test.x, test.y)
          if (result != test.expected) {
              t.Fatal("Expected Result Not Given!")
          }
      }
   }
  

  • cmd result

Go Api test:

• example
  • "net/http"
  • "net/http/httptest"
  • "github.com/stretchr/testify/assert"
  • "testing"

func TestCustomer(t *testing.T){
   w := httptest.NewRecorder()
                          // method    url     body
   req, _ = http.NewRequest("GET", "/customer", nil)
   router.ServeHttp(w, req)
              //    expected              messages    
   assert.Equal(t, 200, w.Code, "return status code should be 200")
}

概念就是:

• httptest.NewRecorder: 幫我記錄我寫的 API(GIN) 回傳內容
• http.NewRequest: 送出 request 去吃我寫的API
• router 就是我用 gin 寫的 api
  • 用 gin 的 ServeHttp Run 起來
• asseet: 再來用直接看回傳的內容是不是預期的樣子

整個感覺就很美～

postman

• Test scripts

pm.test("Status test", function () {
    pm.response.to.have.status(200);
});

let jsonData = pm.response.json();

console.log(jsonData)

pm.test("[GET]", function () {
    pm.expect(jsonData[0].uuid).to.eq("c439f7a8-ec2e-41cc-9e61-6f973a7f952a");
    pm.expect(jsonData[0].len).to.eq(1);
    pm.expect(jsonData[0].name).to.eq("tim");
});

Reference:

• https://www.katalon.com/resources-center/blog/api-testing-tips/

• Positive test
  • Verify that the API receives input and returns the expected output as specified in the requirement.
  • Verify that the response status code is returned as specified in the requirement, whether it returns a 2xx or error code.
  • Specify input with minimum required fields and with maximum fields.
• Negative test
  • Verify that the API returns an appropriate response when the expected output does not exist.
  • Perform input validation test.
  • Verify the API’s behaviors with different levels of authorization.
