/* Package httpmock provides tools for mocking HTTP responses. Simple Example: func TestFetchArticles(t *testing.T) { httpmock.Activate() defer httpmock.DeactivateAndReset() // Exact URL match httpmock.RegisterResponder("GET", "https://api.mybiz.com/articles", httpmock.NewStringResponder(200, `[{"id": 1, "name": "My Great Article"}]`)) // Regexp match (could use httpmock.RegisterRegexpResponder instead) httpmock.RegisterResponder("GET", `=~^https://api\.mybiz\.com/articles/id/\d+\z`, httpmock.NewStringResponder(200, `{"id": 1, "name": "My Great Article"}`)) // do stuff that makes a request to articles // get count info httpmock.GetTotalCallCount() // get the amount of calls for the registered responder info := httpmock.GetCallCountInfo() info["GET https://api.mybiz.com/articles"] // number of GET calls made to https://api.mybiz.com/articles info["GET https://api.mybiz.com/articles/id/12"] // number of GET calls made to https://api.mybiz.com/articles/id/12 info[`GET =~^https://api\.mybiz\.com/articles/id/\d+\z`] // number of GET calls made to https://api.mybiz.com/articles/id/ } Advanced Example: func TestFetchArticles(t *testing.T) { httpmock.Activate() defer httpmock.DeactivateAndReset() // our database of articles articles := make([]map[string]any, 0) // mock to list out the articles httpmock.RegisterResponder("GET", "https://api.mybiz.com/articles", func(req *http.Request) (*http.Response, error) { resp, err := httpmock.NewJsonResponse(200, articles) if err != nil { return httpmock.NewStringResponse(500, ""), nil } return resp, nil }, ) // return an article related to the request with the help of regexp submatch (\d+) httpmock.RegisterResponder("GET", `=~^https://api\.mybiz\.com/articles/id/(\d+)\z`, func(req *http.Request) (*http.Response, error) { // Get ID from request id := httpmock.MustGetSubmatchAsUint(req, 1) // 1=first regexp submatch return httpmock.NewJsonResponse(200, map[string]any{ "id": id, "name": "My Great Article", }) }, ) // mock to add a new article httpmock.RegisterResponder("POST", "https://api.mybiz.com/articles", func(req *http.Request) (*http.Response, error) { article := make(map[string]any) 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 } */ package httpmock
