How to mock Response without executing a request?

[smiklosovic]

Hey,

I want to test my unmarshalling logic and I do not want to make a call to server, I just want to pretend I already got some response. body is package private in Response so how should I set that one?

@smiklosovic you could use any http mocking library with Resty to mock request. for e.g. readme reference

I'm closing this one.

@jeevatkm no worries, I did this for reference

client.testResponse = &resty.Response{
        RawResponse: &http.Response{
            Body:       ioutil.NopCloser(bytes.NewReader([]byte(`{ "my": "json"}`))),
            Status:     "200 OK",
            StatusCode: 200,
    },
}

Then I have some logic around that in my client ..

@smiklosovic when you set a http.Response as a RawResponse, it wouldn't be taken into account e.g. by resty.Response.String().

This quirk makes resty.Response untestable... Illustration:

package main

import (
	"fmt"
	"io"
	"net/http"
	"strings"

	"github.com/go-resty/resty/v2"
)

func mockResponse(status int, body string) *resty.Response {
	rawResponse := new(http.Response)
	rawResponse.StatusCode = status
	rawResponse.Body = io.NopCloser(strings.NewReader(body))

	response := new(resty.Response)
	response.RawResponse = rawResponse

	return response
}

func main() {
	response := mockResponse(200, "body")
	body := response.String()

	fmt.Printf("Response body is: %v\n", body)
}

Have you managed to work around this somehow?

@Kolyunya @smiklosovic I have added Response.SetBody(b []byte) will be released in v2.10.0. I should have done it earlier.
Currently, it's available in v2.10.0-rc.2.

@jeevatkm thanks for a quick fix!
