/*
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/<any-number>
}
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
}
