Overview ¶
Package httptest provides utilities for HTTP testing.
Index ¶
Examples ¶
Constants ¶
const DefaultRemoteAddr = "1.2.3.4"
DefaultRemoteAddr is the default remote address to return in RemoteAddr if an explicit DefaultRemoteAddr isn't set on ResponseRecorder.

Types ¶
type ResponseRecorder ¶
type ResponseRecorder struct {
Code int // the HTTP response code from WriteHeader
HeaderMap http.Header // the HTTP response headers
Body *bytes.Buffer // if non-nil, the bytes.Buffer to append written data to
Flushed bool
// contains filtered or unexported fields
}
ResponseRecorder is an implementation of http.ResponseWriter that records its mutations for later inspection in tests.
Example ¶
package main
import (
"fmt"
"log"
"net/http"
"net/http/httptest"
)
func main() {
handler := func(w http.ResponseWriter, r *http.Request) {
http.Error(w, "something failed", http.StatusInternalServerError)
}
req, err := http.NewRequest("GET", "http://example.com/foo", nil)
if err != nil {
log.Fatal(err)
}
w := httptest.NewRecorder()
handler(w, req)
fmt.Printf("%d - %s", w.Code, w.Body.String())
}
Output: 500 - something failed
func NewRecorder ¶
func NewRecorder() *ResponseRecorder
NewRecorder returns an initialized ResponseRecorder.
func (*ResponseRecorder) Header ¶
func (rw *ResponseRecorder) Header() http.Header
Header returns the response headers.
func (*ResponseRecorder) Write ¶
func (rw *ResponseRecorder) Write(buf []byte) (int, error)
Write always succeeds and writes to rw.Body, if not nil.
func (*ResponseRecorder) WriteHeader ¶
func (rw *ResponseRecorder) WriteHeader(code int)
WriteHeader sets rw.Code.
type Server ¶
type Server struct {
URL string // base URL of form http://ipaddr:port with no trailing slash
Listener net.Listener
// TLS is the optional TLS configuration, populated with a new config
// after TLS is started. If set on an unstarted server before StartTLS
// is called, existing fields are copied into the new config.
TLS *tls.Config
// Config may be changed after calling NewUnstartedServer and
// before Start or StartTLS.
Config *http.Server
// contains filtered or unexported fields
}
A Server is an HTTP server listening on a system-chosen port on the local loopback interface, for use in end-to-end HTTP tests.
Example ¶
package main
import (
"fmt"
"io/ioutil"
"log"
"net/http"
"net/http/httptest"
)
func main() {
ts := httptest.NewServer(http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
fmt.Fprintln(w, "Hello, client")
}))
defer ts.Close()
res, err := http.Get(ts.URL)
if err != nil {
log.Fatal(err)
}
greeting, err := ioutil.ReadAll(res.Body)
res.Body.Close()
if err != nil {
log.Fatal(err)
}
fmt.Printf("%s", greeting)
}
Output: Hello, client
func NewServer ¶
NewServer starts and returns a new Server. The caller should call Close when finished, to shut it down.
func NewTLSServer ¶
NewTLSServer starts and returns a new Server using TLS. The caller should call Close when finished, to shut it down.
func NewUnstartedServer ¶
NewUnstartedServer returns a new Server but doesn't start it.
After changing its configuration, the caller should call Start or StartTLS.
The caller should call Close when finished, to shut it down.
func (*Server) Close ¶
func (s *Server) Close()
Close shuts down the server and blocks until all outstanding requests on this server have completed.
func (*Server) CloseClientConnections ¶
func (s *Server) CloseClientConnections()
CloseClientConnections closes any currently open HTTP connections to the test Server.
