httpmock Build Status

Simple Example:

func TestFetchArticles(t *testing.T) {
    httpmock.Activate()
    defer httpmock.DeactivateAndReset()

    httpmock.RegisterResponder("GET", "https://api.mybiz.com/articles.json",
        httpmock.NewStringResponder(200, `[{"id": 1, "name": "My Great Article"}]`))

    // do stuff that makes a request to articles.json
}

Advanced Example:

func TestFetchArticles(t *testing.T) {
    httpmock.Activate()
    defer httpmock.DeactivateAndReset()

    // our database of articles
    articles := make([]map[string]interface{}, 0)

    // mock to list out the articles
    httpmock.RegisterResponder("GET", "https://api.mybiz.com/articles.json",
        func(req *http.Request) (*http.Response, error) {
            resp, err := httpmock.NewJsonResponse(200, articles)
            if err != nil {
                return httpmock.NewStringResponse(500, ""), nil
            }
            return resp, nil
        },
    )

    // mock to add a new article
    httpmock.RegisterResponder("POST", "https://api.mybiz.com/articles.json",
        func(req *http.Request) (*http.Response, error) {
            article := make(map[string]interface{})
            if err := json.NewDecoder(req.Body).Decode(&article); err != nil {
                return httpmock.NewStringResponse(400, ""), nil
            }

            articles = append(articles, article)

            resp, err := httpmock.NewJsonResponse(200, article)
            if err != nil {
                return httpmock.NewStringResponse(500, ""), nil
            }
            return resp, nil
        },
    )

    // do stuff that adds and checks articles
}
