gtester is a box of utils for testing Golang codes.

CheckeQueue is designed to be a checking execution container, and run them successively, stop and return the error after the first fail execution.
Simple example
import (
"fmt"
"github.com/Focinfi/gtester"
)
func main() {
base := 0
cq := gtester.NewCheckQueue()
cq.Add(func() error {
base++
return nil
}).Add(func() error {
base++
return fmt.Errorf("check2")
}).Add(func() error {
base++
return fmt.Errorf("check3")
}).Run()
gtester.AssertEqual(t, len(cq.Checks), 3)
gtester.AssertEqual(t, cq.Err.Error(), "check2")
gtester.AssertEqual(t, base, 2)
}mockhttp provide a container for a http.Handler, and a series of methods to access this Handler and return a reponse for testing.
Simple example
import (
"encoding/json"
"net/http"
"github.com/Focinfi/gtester/httpmock"
)
func main() {
respJson, _ := json.Marshal(map[string]string{"hello": "world"})
handler := func(wr http.ResponseWriter, req *http.Request) {
wr.WriteHeader(http.StatusOK)
fmt.Fprint(wr, string(respJson))
}
mux := http.NewServeMux()
mux.HandleFunc("/hello", handler)
// set mux as http.Handler to httpmock for later testing
httpmock.ListenAndServe("hello.com", mux)
// request a GET /hello/1 with a empty body
response := httpmock.GET("/hello/1", nil)
// we can check the response to test the mux
response.Code == http.StatusOK // true
response.Body.String() == string(respJson) // true
}Besides httpmock.GET(), httpmock has other convenient methods to make requesting easier, use a map[string]interface{} as parameters or form values. Note that the interface{} only accepts string and int, ortherwise error will not be nil.
PATCH(urlStr string, form map[string]interface{}) (*Recorder, error)
POSTForm(urlStr string, form map[string]interface{}) (*Recorder, error)
PUT(urlStr string, form map[string]interface{}) (*Recorder, error)Also, if you wanna use a customized body, use the POST()
POST(urlStr string, body io.Reader) *Recorder
DELETE(urlStr string, body io.Reader) *Recorder
