Advantage Usage

package main

import (
	"testing"
)

func Test_Request(t *testing.T) {
	host := "https://example.com"
	client := httptesting.New(host, true)

	t.Run("GET /api/json", func(t *testing.T) {
		request := client.New(t)
		request.WithHeader("X-Mock-Client", "httptesting")

		// assume server response with following json data:
		// {"user":{"name":"httptesting","age":3},"addresses":[{"name":"china"},{"name":"USA"}]}
		request.GetJSON("/api/json", nil)

		// verify http response status
		request.AssertOK()

		// verify http response header
		request.AssertHeader("X-Mock-Client", "httptesting")

		// verify http response body with json format
		request.AssertContainsJSON("user.name", "httptesting")

		// for array
		request.AssertContainsJSON("addresses.1.name", "USA")
		request.AssertNotContainsJSON("addresses.2.name")

		// use regexp for custom matcher
		request.AssertMatch("user.*")
	})

	t.Run("POST /api/json", func(t *testing.T) {
		request := client.New(t)
		request.WithHeader("X-Mock-Client", "httptesting")

		payload := struct {
			Name string `json:"name"`
			Age  int	`json:"age"`
		}{"httptesting", 3}

		// assume server response with following json data:
		// {"data":{"name":"httptesting","age":3},"success":true}
		request.PostJSON("/api/json", payload)

		// verify http response status
		request.AssertOK()

		// verify http response header
		request.AssertHeader("X-Mock-Client", "httptesting")

		// verify http response body with json format
		request.AssertContainsJSON("data.name", "httptesting")
		request.AssertContainsJSON("data.age", 3)
		request.AssertContainsJSON("success", true)

		// use regexp for custom matcher
		request.AssertNotMatch("user.*")
	})
