+# [acme-challenge-test](https://git.rootprojects.org/root/acme-challenge-test.js.git) | a [Root](https://rootprojects.org) project
 
-The test harness you should use when writing an ACME challenge strategy
+Test harness for ACME http-01 and dns-01 challenges for Let's Encrypt Free SSL integration.
-for [Greenlock](https://git.coolaj86.com/coolaj86/greenlock-express.js) v2.7+ (and v3).
 
-All implementations MUST pass these tests, which is a very easy thing to do (just `set()`, `get()`, and `remove()`).
+This was specificially designed for [ACME.js](https://git.coolaj86.com/coolaj86/acme-v2.js) and [Greenlock.js](https://git.coolaj86.com/coolaj86/greenlock-express.js), but will be generically useful to any ACME module.
 
-The tests account for single-domain certificates (`example.com`) as well as multiple domain certs (SAN / AltName),
+> If you are building a plugin, please let us know.
-wildcards (`*.example.com`), and valid private / localhost certificates. As someone creating a challenge strategy
+> We may like to co-author and help maintain and promote your module.
-that's not something you have to take special consideration for - just pass the tests.
 
-## Install
+This package has been split in two for the purpose of keeping the documentation clear and concise.
 
-```bash
+## ACME http-01
-npm install --save-dev acme-challenge-test@3.x
-```
 
-## Usage
+Use this for quick-and-easy, average-joe kind of stuff.
 
-```js
+- See <https://git.rootprojects.org/root/acme-http-01-test.js>
-var tester = require("acme-challenge-test");
 
-//var challenger = require('acme-http-01-cli').create({});
+## ACME dns-01
-//var challenger = require('acme-dns-01-cli').create({});
-var challenger = require("./YOUR-CHALLENGE-STRATEGY").create({});
 
-// The dry-run tests can pass on, literally, 'example.com'
+Use this for wildcards, and private and local domains.
-// but the integration tests require that you have control over the domain
-var domain = "example.com";
 
-tester.test("http-01", domain, challenger).then(function() {
+- See <https://git.rootprojects.org/root/acme-dns-01-test.js>
-	console.info("PASS");
-});
-```
 
 ## Reference Implementations
 
 These are plugins that use the v2.7+ (v3) API, and pass this test harness,
 which you should use as a model for any plugins that you create.
 
-- [`acme-http-01-cli`](https://git.rootprojects.org/root/acme-http-01-cli.js)
+- http-01

+You can find other implementations by searching npm for [acme-http-01-](https://www.npmjs.com/search?q=acme-http-01-)
+and [acme-dns-01-](https://www.npmjs.com/search?q=acme-dns-01-).
 
-See `example.js` (it works).
+## Starter Template
 
-## Overview
+Just so you have an idea, this is typically how you'd start passing the tests:
-
-Here's a quick pseudo stub-out of what a test-passing plugin object might look like:
 
 ```js
-tester.test('http-01', 'example.com', {
+var tester = require('acme-challenge-test');
-  set: function (opts) {
-    var ch = opts.challenge;
-    // { type: 'http-01' // or 'dns-01'
-    // , identifier: { type: 'dns', value: 'example.com' }
-    // , wildcard: false
-    // , token: 'xxxx'
-    // , keyAuthorization: 'xxxx.yyyy'
-    // , dnsHost: '_acme-challenge.example.com'
-    // , dnsAuthorization: 'zzzz' }
 
-    return API.set(...);
+// The dry-run tests can pass on, literally, 'example.com'
-  }
+// but the integration tests require that you have control over the domain
-, get: function (query) {
+var domain = 'example.com';
-    var ch = query.challenge;
-    // { type: 'http-01' // or 'dns-01', 'tls-alpn-01', etc
-    // , identifier: { type: 'dns', value: 'example.com' }
-    //   // http-01 only
-    // , token: 'xxxx'
-    // , url: '...' // for testing and debugging
-    //   // dns-01 only, for testing / dubgging
-    // , altname: '...'
-    // , dnsHost: '...'
-    // , wildcard: false }
-    // Note: query.identifier.value is different for http-01 than for dns-01
 
-    return API.get(...).then(function (secret) {
+tester
-      // http-01
+  .testRecord('http-01', domain, {
-      return { keyAuthorization: secret };
+    set: function(opts) {
-      // dns-01
+      console.log('set opts:', opts);
-      //return { dnsAuthorization: secret };
+      throw new Error('set not implemented');
-    });
+    },
-  }
-, remove: function (opts) {
-    var ch = opts.challenge;
-    // same options as in `set()` (which are not the same as `get()`
 
-    return API.remove(...);
+    remove: function(opts) {
-  }
+      console.log('remove opts:', opts);
-}).then(function () {
+      throw new Error('remove not implemented');
-  console.info("PASS");
+    },
-});
+
+    get: function(opts) {
+      console.log('get opts:', opts);
+      throw new Error('get not implemented');
+    }
+  })
+  .then(function() {
+    console.info('PASS');
+  });
 ```
-
-Note: The `API.get()`, `API.set()`, and `API.remove()` is where you do your magic up to upload a file to the correct
-location on an http serever, set DNS records, or add the appropriate data to the database that handles such things.
