Challenge Test Server

The challtestsrv package offers a library/command that can be used by test code to respond to HTTP-01, DNS-01, and TLS-ALPN-01 ACME challenges. The challtestsrv package can also be used as a mock DNS server letting developers mock A, AAAA, and CAA DNS data for specific hostnames.

Important note: The challtestsrv command and library are for TEST USAGE ONLY. It is trivially insecure, offering no authentication. Only use challtestsrv in a controlled test environment.

For example this package is used by the Boulder load-generator command to manage its own in-process HTTP-01 challenge server.

Usage

Create a challenge server responding to HTTP-01 challenges on ":8888" and DNS-01 challenges on ":9999" and "10.0.0.1:9998":

  import "github.com/letsencrypt/pebble/challtestsrv"

  challSrv, err := challtestsrv.New(challsrv.Config{
    HTTPOneAddr: []string{":8888"},
    DNSOneAddr: []string{":9999", "10.0.0.1:9998"},
  })
  if err != nil {
    panic(err)
  }

Run the Challenge server and subservers:

  // Start the Challenge server in its own Go routine
  go challSrv.Run()

Add an HTTP-01 response for the token "aaa" and the value "bbb", defer cleaning it up again:

  challSrv.AddHTTPOneChallenge("aaa", "bbb")
  defer challSrv.DeleteHTTPOneChallenge("aaa")

Add a DNS-01 TXT response for the host "_acme-challenge.example.com." and the value "bbb", defer cleaning it up again:

  challSrv.AddDNSOneChallenge("_acme-challenge.example.com.", "bbb")
  defer challSrv.DeleteHTTPOneChallenge("_acme-challenge.example.com.")

Get the history of HTTP requests processed by the challenge server for the host "example.com":

requestHistory := challSrv.RequestHistory("example.com", challtestsrv.HTTPRequestEventType)

Clear the history of HTTP requests processed by the challenge server for the host "example.com":

challSrv.ClearRequestHistory("example.com", challtestsrv.HTTPRequestEventType)

Stop the Challenge server and subservers:

  // Shutdown the Challenge server
  challSrv.Shutdown()
